Why a collection of artists' letters?

How to explain the reasons for the appearance of Giovanni Gaetano Bottari's Raccolta, the first collection of artists' letters, in 1754? Giovanna Perini Folesani [40] saw in it the culmination of a XVII-Century tradition of collecting the letters of the artists, which dated back to Bellori (1613-1696) and Malvasia (1616-1693), or to art writers whom Bottari appreciated as absolute reference points of his aesthetics: it is not by chance that one of the two characters of his Dialoghi sopra le tre arti del disegno (Dialogues above the three arts of drawing) published in 1754 was Bellori, while Malvasia was continually cited in that work.

According to the scholar, there was evidence that Bellori made a first attempt to publish his collection of letters in 1665 [41]. In his speech on the Idea of 1664, moreover, he inserted a letter by Guido Reni. As for Malvasia, he had arranged a collection of letters from artists (including 150 from Albani and 60 from the Carraccis) and tried, in vain, to publish it in 1672, as an independent (parallel) project to the Felsina Pittrice. In fact, Malvasia had reserved a key role to letters also in his Felsina: "Indeed, for the lawyer Malvasia, now dressed in the toga of the historian, the written document (the letter in particular) was, like a verbal testimony, a voice that dialogued with other favourable or adverse views, an element on which a closing statement in front of the court might rest or that, conversely, had to be refuted: with a declared aim to obtain a hopefully favourable judgment” [42].

According to Ms Perini, Bellori and Malvasia would therefore be the true first creators of a collection of artists' letters, while Bottari had ‘only’ the merit to be the first to implement a project in reality planned in the previous century. Why did Bellori’s and Malvasia’s projects not materialize, while the one of Bottari did so? In the XVII Century, in her view, the time to publish a collection of letters was not yet ripe: she wrote that letters, ultimately, are "self-referential documents, free from a biographical individuality to be historically ascertained or from a theory to be implemented or refuted” [43]. In other words, for writers with a strong aesthetic identity such as Bellori and Malvasia, writing a ‘simple’ collection of neutral texts without a uniform orientation would have made no sense. In addition (as already mentioned in the first part of this post), while compiling an anthological history of poetry did not pose problems of unrepresented authors, writing an art history through the letters of the artists was intricate, because it clashed with the absence of documents for many of the major artists, and their abundance for some minor authors. For Ms Perini, thus, one should wait for the "historiography of weak profile” [44], typical of the XVIII Century (i.e. a phase in which simple erudition was really the exclusive end goal of historical research), before a collection of artists' letters could appear: "In short, it is not fortuitous that the first collection of artist's letters was released in the mid-XVIII Century and not before: its heterogeneity, additivity and apparent objectivity corresponded to a level of pure documentation, of teleological indifference, or at least of attraction, impossible to implement within the context of theoretical motivation and concrete polemics of XVII Century historiography” [45].

I would like to disagree, in particular, with the idea that Bottari's Raccolta was born in an environment of 'weak thought', to use this poststructuralist concept of last century’s philosophy. What has just been mentioned about the 'ideological' reasons of the instrument of historical sources by the Jansenists would oppose, in my opinion, the thesis of Ms Perini Folesani. Furthermore, the significance of the Raccolta could not be fully understood, if one did not consider that the epistolary form imposed itself, in late XVII-Century Europe, as a key instrument of communication between those who were interested in culture; this did not take place exclusively as a private contact, but also as a testimony destined to a wider circulation.

It goes without saying, of course, that Bottari made systematic use (as a source for the Raccolta, especially in Tome V of 1766) of the many Venetian ‘cinquecentine’ which offered series of letters by famous men (published and edited, among the others, by Paolo Manuzio, Paolo Gherardo, Ludovico Dolce, Dionigi Atanagi, Bernardino Pino and Francesco Turchi) and did certainly not ignore the conceptualization of the epistolary instrument already widespread in the early XVII Century (think of "The idea of ​​various letters used in the secretariat of every prince, and lord with different conceptual principles, and purposes of the missive" by Benedetto Pucci, published in 1608). And yet, precisely in the XVIII Century, the letter became a fundamental tool not only for bilateral communication, but also for the dissemination of knowledge. Since 1684 we have been speaking, not surprisingly, of République des Lettres, with the expression coined by Pierre Bayle (1647-1706). The main men of culture wrote and retained their correspondence, also in the perspective of publication. Also in the case of art, with the circulation of magazines debating on artistic themes, the publication of the letters became a privileged form of aesthetic discussion [46].

A second process - contemporary to the first one - was the diffusion of the collections of texts. In France, the Recueil des plus belles pièces des Poètes français, tant anciens que modernes (Collection of the most beautiful pieces of French Poets, both ancient and modern) in five volumes attributed to Bernard Le Bouyer (or Bovier) De Fontenelle, (1657-1757), was released in 1692. The first Italian anthology of modern times was the Scelta di sonetti e canzoni de' più eccellenti autori d'ogni secolo (Choice of sonnets and songs by the most excellent authors of every century), published as a posthumous work by Agostino Gobbi (1684-1708) between 1709 and 1711. It was an anthological story of Italian poetry in four volumes (the first volume about poetry up to 1550, the second about the following centuries and the last two with the works of living poets).

Bottari himself participated to this 'anthological' movement; in his thirties, in fact, he contributed in Florence to the Raccolta Di Prose Fiorentine (Collection of Florentine Prose, 1716-1745) in 5 volumes and to the Latin collection Carmina illustrium poetarum italorum (Collection of Illustrious Italian Poets, 1719-1726) in 11 volumes. As for the first series of volumes, it was the continuation of a collection begun in Mid-1600 by the Florentine philologist Carlo Dati [47] (1619-1676) and interrupted at his death; Bottari participated in the XVIII-Century extension of the work together with Tommaso Buonaventuri [48] (1675-1731) and Rosso Antonio Martini (1696-1762), within the Accademia della Crusca. As for the second series, edited by Bottari always with Tommaso Buonaventuri, it was a collection of Italian poetry in Latin, where the authors were reported (from the first volume) in alphabetical order: this means that the immense wealth of poetry had already been ordered before the publication’s start.

Obviously, there had been collections of literary texts (starting from the "Parnasse des poètes françois modernes" of 1571) already in previous centuries. And yet, from the end of the XVII Century, literary anthologies flourished everywhere, consolidating as a massive phenomenon in the XVIII Century. What are the reasons of this proliferation? Italian scholars seem to have ignored the question. French [49] and German [50] studies on the subject identified at least three, often closely interrelated causes. First of all, the increasing diffusion of repertoires to support scholarship from the end of the XVII Century (it is the erudite element already identified by Ms Perini, which should however not be interpreted as an expression of a minor culture, but on the contrary conceived of as one of the earliest expressions of encyclopaedism); then the explosion of publishing and of the number of books, which made it necessary to offer the reader new tools to be able to selectively approach literature without having to fill the houses with volumes and spend excessive amounts; finally, the affirmation of a more 'ideological' vision of the history of literature, which pushed to 'codify' the literary heritage according to a coherent interpretative thesis going, in reality, beyond the production of a simple anthology of texts. For example, Fontenelle compiled an anthology of French poetry to demonstrate the superiority of moderns over the ancients, while Gobbi wanted to proclaim the primacy of petrarchism through the centuries, up to its contemporaries. It is evident - in the work on the Latin literature of Bottari and Buonaventuri - the desire to demonstrate the continued vitality of the use of Latin in the world of letters in Italy, starting from Petrarch and Poliziano up to the XVIII Century. The accentuation of the three factors (erudition, publishing and ideology) would make the anthology one of the most successful genres of the following century, the XIX Century.

The Florentine origins of the Raccolta

We have already said in the first part of this post that Bottari edited a proto-anthology, which preserved some historical elements of erudite repertoires, displaying however some characteristics of the first anthologies. Moving from theory to practice, and therefore from the theory of the anthological form to historical reality, I am absolutely convinced that the roots of the Raccolta date back to the years when Bottari was still active as an intellectual in Florence (and participated - together with Rosso Antonio Martini and Tommaso Buonaventuri - to the already mentioned collections of Florentine prose and Latin poetry). An important source (in fact, one of the letters contained in the Tome II of the Raccolta) illustrates what happened. Francesco Maria Niccolò Gabburri (1675-1742) wrote a very long letter to Pierre-Jean Mariette on October 4, 1732, and told him about a first project to publish artists’ letters, which was interrupted by the death of Abbot Antonio Maria Salvini [51] (1653-1729). Three years had passed and a group of Florentine scholars wanted to relaunch that project. Gaburri wrote about Rosso Antonio Martini’s intention of publishing a tome of "Letters of Painters, Sculptors, and Architects", and explained that he himself had contributed by providing him some interesting letters from Salvator Rosa. He added he was hoping to collect other letters from Bolognese correspondents and asked Mariette to try searching in Paris letters of French painters; he explained, finally, that everything had to be ultimately forwarded to Martini as coordinator of the work. Rosso Antonio Martini (also called the 'Ripurgato') was an academic of the Crusca since 1719, chief officer of the Royal Printing (where also Bottari worked with a managerial role in those years) and director of the archives of the Academy. He was a central figure to organize the systematic sieve of the great Florentine archives and to identify letters of artists. So the origins of the collection were Florentine and dated back to the years between the second and third decades of the XVIII Century.

In addition to the letter from Gabburri, the Raccolta offered us other testimonies of the search for artists' letters ("lettere pittoresche"), which became object of intense letter exchanges just around 1732. The network of correspondents was going beyond Tuscany and included direct relations between Paris and Bologna, at the search of written evidence about the Emilian painters of the early XVII Century. The Bolognese designer and expert Giampietro Zannotti informed Mariette on June 3 that he owned some letters from Albani, Guido Reni, Algardi, Ludovico Carracci and others (and he stated he would agree in principle to let copy them for circulation and publication); he then added that one of his 'friends' had also many Albani’s letters (originally owned by Malvasia), although he had no idea of ​​their content (and could not verify it because his friend was out of town). On 5 August Zanotti wrote to the Florentine Gabburri to rectify the information: Albani’s letters - which he hoped to find at his friend’s house - were no longer to be found, and he could only provide a copy of his owns; on September 6 he sent a copy of the letters to Florence, admitting that he had overestimated the number of artists' letters in his possession (many had been lost in a move). Other letters were sent on October 4th. All in all, however, the search for texts in Bologna had - at least for the moment - limited fortune.

In 1754 Bottari will confirm in the introduction of the Raccolta that the 'primeval' collection was ready many years before. He will then mention the centrality of the Tuscan friends, thanking first of all Rosso Antonio Martini, but also the painter Ignazio Enrico Hugford (1703-1778), born in Tuscany but of English origin. It must be said from now on that the two will continue to support Bottari's effort for decades: traces of Martini's contribution will be found until Tome III (1759), to which he contributed with sixty-five letters from the XVI Century in Tuscany, while Hugford’s support will include around one hundred letters sent by many senders to Gabbiani and Gabburri, published in Tome II (1757). Hugford will be still thanked in Volume V (1766) for the 'many letters' he collected and published there and will finally appear as a direct correspondent in Tome VI (1768).


Bottari as an art writer in the 1750s

So, what was Bottari's intention when he resumed, in the 1750s, the work which Salvini, Gaburri and Rosso Martini has started twenty years earlier? According to Serenella Rolfi Ožvald [52], far from wanting to assemble texts for mere reasons of scholarship, he aimed at affirming a new way of narrating the history of art, alongside the consolidated mechanism of the biographical story (which he knew perfectly, preparing to take care of the first commented edition of Vasari's Lives in 1759 -1760, and having already mentioned with great abundance both Vasari’s Lives of Vasari and Malvasia’s Felsina Pittrice in his own Dialogues above the three arts of drawing of 1754). He privileged, in fact, the modern method of setting up a chronological collection of the letters of the artists, letting “professori” (the artists) and/or “personaggi” (the broader connoisseurs) speak directly. Ms Rolfi Ožvald noted that the Raccolta not only contained letters from the past (taken from archives and libraries, to which Bottari had privileged access both because of her professional position and thanks to a very large network of friends who supported him in the research) but, starting from his transformation from a single volume (1754) into a series of texts (1757 onwards) also included the letters that Bottari himself was exchanging with other protagonists of the aesthetic debate, such as the aforementioned Mariette. Some letters (for example that sent by Luigi Crespi to Bottari himself on the life of his father Giuseppe Maria, probably dating back to 1756 and published in Tome III, and that of the decorator Giovanni Battista Ponfredi (or Ponfreni) (1714-1795) to Count Nicola Soderini on the life of his teacher, the painter Marco Benefial, published in Tome V and dated 1764) were nothing other but substitutes for the lives of artists, according to the ancient Vasari model. Following the fashion of the time, some texts published in essays or in magazine articles of the time were even artificially 'converted' by Bottari into letters in order to appear in the Raccolta. These were not manipulations or fakes, but the expression of the passion of those years for all what is literary, in the original sense of the term 'letter'.

A reading of the Raccolta as a new form of story in the history of art was also proposed in 1984 by Paola Barocchi: "All this is made possible by a balanced historical consciousness that, while drawing on the most famous literary anthologies, did not let itself be tempted by the abstractness of the ekphrasis, but was concerned with enhancing, through the testimonies of connoisseurs, collectors and scholars, the fortunes of artists and works and their contexts. In this sense, the simultaneity of the Collection of Letters and of Vasari’s re-edition drew full coherence in the evident opposition to the popularizing and reductive aspirations of the contemporary Abecedari. Thus a sort of history of history was born within the artistic epistolography, which in a certain way anticipated the great history of Lanzi and its dual interest for the ancient and the modern” [53]. Collecting the letters meant, at the same time, to verify from direct sources the narrative of the biographers (Vasari, Baldinucci, Malvasia and many others) [54] and to be confronted directly with the world of the artists. Even the early emulators of Bottari (including Ticozzi and Gualandi, with the exclusion however of Gaye and, I would add, also of Guhl, both impregnated with elements of positivism thanks to their studies in Berlin) did not therefore fully realize, according to Ms Barocchi, the methodological novelty of the anthological genre. In fact, Bottari’s work offered a new tool for understanding the socio-cultural context within which the artists were moving.


Looking for an interpretation: the Dialogues above the three arts of drawing (1754)

Let us consider again a central question: was the collection of letters just a (highly laudable) scholarly collation or was there a silver threat going beyond the assembly of texts? To try and answer this question, I also read the Dialogues on the three arts of drawing, prepared and published by Bottari in parallel with the 1754 Raccolta. The two virtual characters of the Dialogues were Giovanni Pietro Bellori (1613-1696) and Carlo Maratta (1625-1713), or two central figures of the Roman artistic life who had passed away when Giovanni Gaetano was only seven and twenty-four years respectively. Both of them had been exponents of that way of thinking about art that is often cited as Roman classicism. The Dialogue had therefore the tone of a conversation between friends who did not need, in fact, to convince each other of their correctness, sharing the same fundamental views (in short, there were no particularly aggressive tones in their conversations).

It must be said, first of all, that the Dialogues proved to be well written, revealing still today, in my opinion, a great ease of writing, almost three hundred years after the text had been drafted. Unlike what I expected, it was neither a text of aesthetics on beauty nor a discussion on style (as the presence of Bellori would have suggested). Nor was it a conversation about painting technique, as the choice of giving the word to a painter like Maratta might have suggested. The central theme of the five virtual conversations was, in fact, the difficulty - I would almost say the absolute impossibility - for the artists (here called ‘professors’, the same term used in the 1754 Raccolta) to be understood by their interlocutors, with the exception of a small group of 'experts'.

In short, the Dialogues dealt with a very modern theme: the artist would be alone, misunderstood, and a victim of the arrogance of the powerful and the ignorance of most; he would be trapped by aesthetic evaluations most often conceived in the past and unhelpful to understand the present (and which, therefore, would hinder the renewal of the arts). Nothing could be further from the neoclassical assessment that true artists should assert themselves as the champions of the imitation of the past according to precise canons. According to Giovanni Gaetano, instead, the past events of the artists’ lives could not but confirm the miseries of the present. In short, the many quotations in the texts of art writers of the past (taken from the art writings of authors like Vasari, Baldinucci, Malvasia, and Ridolfi) never aimed at confirming the neoclassical obligations of sticking to past standards, but served to confirm that the weakness of the artist’s human condition had always been persistent (and this perhaps explains why Winckelmann had an opinion negative on the Dialogues, which he considered "silly, dry and childish” [55]). For this reason the Dialogues ended in a substantially pessimistic tone, as stated by Maratta: there would perhaps be no hope – also in the future –  for artists to be completely understood.

The frontispiece - while containing the reference to the title in the base of the altar - was taken from a much earlier image, designed by Niccolò Berrettoni (1637-1682) and engraved by Benoît Farjat (1646-1724). Berrettoni and Farjat collaborated with Carlo Maratta, one of the protagonists of the Dialogues.

The first two dialogues were all centred on the theme of the relationship between artist and power. In the first one, the conversation was supported by numerous and long quotations of Vasari's Lives, all of which were demonstrating how even the greatest painters and sculptors (like Michelangelo himself) were confronted with the greatest difficulty to gain and preserve their room of autonomy from powerful politicians. The arbitrary decisions of people detaining power often put the artists in extreme difficulty. In the second dialogue the presence of Vasari continued, but their quotations were progressively more and more juxtaposed by passages of other art writers from Tuscany (Baldinucci) or Emilia (Carlo Cesare Malvasia, the contemporary Giampietro Zanotti, the latter mentioned three times) or antiquity (the Latin Vitruvius), as if there were an implicit hierarchy in their entrance on stage. The prevailing theme of the injustice of the potent vis-à-vis artists did not vary, but it was here extended to architecture. The powerful were paying a miserable income to valuable architects (like Brunelleschi) and covered with gold those who worked badly. For fear of costs, the tasks were assigned to secondary architects, for projects whose final price was double compared to the beginning. Even the best ones (like Bernini) were victims of envy. A chronological progression led Bellori and Maratta even to touch recent themes for Bottari, such as the useless polemics about the solidity of St. Peter's dome in Rome that developed between 1742 and 1753 (when both Bellori and Maratta had already died for decades) [56]. Obviously, Bottari reserved himself the right to violate any temporal coherence to urge the reader's attention to current and urgent matters. From a geographical point of view, the discussion between the two virtual protagonists arose on Florentine themes, but then developed on Roman issues and finally widened to the difficulties encountered by architects in Venice and Mantua, in a kind of tour touching all the major schools. Finally, the dialogues turned back to discussing art in Rome, to focus once again on the difficulties of building St. Peter's (Bottari let Maratta say words that were not very generous towards the façade of Maderno, as it was not very respectful of Michelangelo's original plans). Then Bottari introduced contemporary themes, like the reconstruction of the façade of Villa Medici in 1741. The discussants concluded that good taste was running out and that architects were less and less capable.

Also the third dialogue was all about architecture and the very difficult equilibrium that was always required between engineering skills (which must be learned) and design (which are innate in the artist): due to this mix, being an architect would be a difficult and professionally risky job. The leitmotiv of the conversation was, once again, the impossibility of communicating: "Those who study architecture do not profess it, and those who profess it do not study it” [57]. The two protagonists discussed, first of all, the merits of an architecture based on good construction practices (and mentioned the case of Brunelleschi, who managed to build the dome despite the exceptional technical difficulties, and of Domenico Fontana, which raised the Antonina Column solving a series of contingencies through last minute solutions). The discussants praised then Alessandro Galilei and - among the technically most educated architects - Borromini. Architecture was seen as a logical exercise (and compared to the game of chess). As bad architects did not know the technique, they were making buildings that would collapse during construction; with their inexperience, they were causing serious accidents at work, which they charged to the insufficient skills of the workers. The mastery of the techniques, however, would be a necessary, but not sufficient condition: some technically perfect works would be horrible from an aesthetic point of view (and here Bottari made a new leap forward in time, dedicating a solemn crunch to the Trevi Fountain started by Nicola Salvi in ​​1731 and still under construction in the years of publication). The primacy of good taste would explain the large number of good architects who were, first of all, painters or sculptors (Michelangelo, Bernini and many others). Many others copied them, but produced buildings without grace (and many churches whose façades were, in the opinion of the dialogues, unacceptable, such as that of St. Peter); the exceptions of good 'pure architects' who were not universal artists themselves were few (Brunelleschi, Buontalenti, Borromini, Vignola) and in any case always interpretable. As for the sources of art history mentioned here, Bottari returned to the Latin classics (Pliny and Vitruvius) and to Vasari.

The fourth dialogue returned to the late XVI Century and the Baroque (with frequent quotations from Malvasia, Baldinucci and Ridolfi): the victims of the patrons’ incomprehension of the clients were prominent names such as Titian, Correggio, Paolo Veronese, Agostino and Annibale Carracci, Guido Reni, Poussin, Taddeo Zuccari, Domenichino, but also less-known artists such as Fabrizio Boschi, Simone Cantarini, Angelo Michele Colonna and Agostino Mitelli. In some cases their works were distorted because of absurd requests, in others the artists were underpaid, in others patrons preferred to them second-class colleagues (Spagnoletto and Lanfranco, whom clearly Bottari disliked, were preferred to Domenichino). In particular Annibale Carracci and Domenichino were seen as the prototype of the artist victim of a cruel fate, as well as of ignorance and human envy.

The fifth and last dialogue was a variation on the theme, always supported by multiple citations from writings of Malvasia, Baldinucci and Ridolfi. As a good Jansenist, Bottari did not believe in papal infallibility (even in terms of art) and paid particular attention to cases where the popes made sensational mistakes. Sixtus IV (1414-1484) paid much more Cosimo Rosselli than Perugino or Luca Signorelli for the frescoes in the Sistine Chapel; also Sixtus V (1521-1585) and Paul V (1550-1621) let secondary artists decorate the Vatican library and forgot the Carraccis and their school in Bologna. The Dominicans in Bologna preferred a fresco maker of poor quality, like Giovanni Valesio (1579 - 1650) to Tiarini, but the result was so disappointing that the painter was forced to cover his entire work with lime in one single night. Artists could also be a victim of bad luck: the disappearance of works was often a consequence of negligence or poorly made restorations (and here Bottari quoted, with Giotto, for the first time an artist of the Middle Ages; the most serious case was however the loss of the frescoes by Guido Reni at S. Michele in Bosco in Bologna) or of wall collapses and other technical incidents. An inexperienced chief engineer determined the vanishing of the frescoes by Agostino Carracci in the Capuchin convent of Parma, accelerating his death. Incidents and bad luck persecute Cigoli and Giulio Romano. Then there were works of the greatest artists of the past (like Raphael and Michelangelo) who would require urgent rescues. The work ended in a tone of deepest disappointment and pessimism.

It remains to say that Bottari’s Dialogues (now almost forgotten) had a respectable fortune for centuries. A new "corrected and augmented" version were brought out already in Florence in 1770 and in Naples in 1772 (therefore with Bottari still alive). In 1804 also a Spanish edition appeared (Dialogos Sobre Las Artes del Diseño). New Italian editions were printed in Reggio Emilia 1826, 1832 and 1845. Evidently the text was well suited to the concerns of the "romantic" era and to the idea of the accursed artist, who prevailed in the readers' fashion during the decades of the new XIX Century editions. Another indication corroborates the, perhaps daring, hypothesis of the Bottari’s pre-Romantic suggestions (although he certainly belonged to the classicist world): it was the friendship between Bottari and Piranesi [58], a rebel spirit who interpreted love for ancient architecture in a completely different sense from that of Winckelmann.

The Dialogues confirmed the idea - which is in line with the idea of Bottari as 'committed intellectual' and proponent of a minority religious tendency (Jansenism) in Italy - of a challenging and complex vision of the relationship between art and society. Bellori and Maratta did not talk about abstract issues or general principles, but about people's destiny. They basically posed behavioural and ethical questions: Who depends on whom? Who has the fault of what? How can we defend ourselves against the wrongs suffered? Obviously, many of their conversations re-presented arguments and rhetorical figures that were not original. For example, the question of what would account more for good architecture (i.e. whether technical-engineering knowledge or the artist's creativity), went back to Vitruvius, as documented by long quotations; moreover, both Vasari and Malvasia had already documented numerous cases in which artists were the victims of an ignorant or stupid client. And yet Giovanni Gaetano also wanted to convey to the reader a precise idea: artists are men who are able to take a risk but are often unsuccessful. Failing is possible and it is an inevitable part of life. Fortune can come to artists very soon or only posthumously, but it never depends solely on their qualities.

The Raccolta in the edition of 1754

Let's try to use what has been learned about the Dialogues to read the volume of the Collection of letters on painting, sculpture and architecture in the version prepared in the thirties of the XVIII Century, presented to the authorities in 1751 and printed in 1754. On that date Giovanni Gaetano, most likely, intended to print a single volume only; he structured it so that it would offer a cohesive idea of the epistolary writings by the artists.

The Raccolta was dedicated to Silvio Valenti Gonzaga (1690-1756), Secretary of State of Benedict XIV (and therefore, in fact, number two of the political structure of the state). Valenti was very interested in art (he founded the Capitoline Art Gallery and collected "a treasure of prints, drawings, and paintings to envy a Monarch" [59]). It must be said that Bottari had dedicated to him, six years before, one of his writings on science, and notably on earthquakes: "Three Lessons over Earthquakes dedicated to the most eminent and prince cardinal Silvio Valenti, chamberlain of the Holy Church, and secretary of state" (1748).

As for the structure of the Raccolta, Bottari apparently stated in the introduction that there was really no order: "While one could make an attempt to observe the existence of an order in arranging the letters, this could not be entirely precise, since it was not necessary, nor would it had been possible, since I received many letters during the printing process” [60]. However, I would consider this statement as too defensive and not accurate: while in a (few) cases the letters were badly placed in order, in most cases the chronological structure held.

The volume contained 203 letters. The first was from 1504, and it was in truth the only one of the early years of the XVI Century, traced in the Gaddi archive in Florence: it was a letter to Piero Soderini (1450 -1522), Gonfalonier of the Republic of Florence, which Giovanna da Montefeltro delle Rovere (1463 -1513) would have sent to recommend a young, twenty-one old, Raphael. It would reveal itself, with the passing of centuries and studies, as a fake. The Raccolta did not include any previous text, not only because Bottari did not seem interested in the primitives, but probably also because the availability of texts of those years was much more scarce in the Florentine and Tuscan archival collections to which the anthologizer had access. The most recent letter was from 1665 and was sent by Salvator Rosa to his friend Giovanni Battista Ricciardi (1623-1686), a poet, playwright and philosopher from Pisa; it was the latest in a long series of letters that Rosa had sent to the same recipient since 1652.


A collection of letters identified by Bottari sorting the archival funds of the recipients

The letters were presented in chronological order, but in a very curious way. Instead of being listed and proposed according to the senders, they were organized according to the recipients. Considering the people to whom the letters were sent, there seem to be five groups of letters: those to the humanist Benedetto Varchi (1503-1565); to the secretary of Cosimo I Jacopo Guidi (1514-1588); to the notable, writer and collector Ferrante Carlo (1578 - 1641) (it was the pseudonym of Ferdinando Carli [61]); to the scholar and art patron Cassiano dal Pozzo (1588-1657); and finally to the playwright Giovanni Battista Ricciardi (1623-1686) [62]. With the exception of the letters sent to Varchi (in the context of the discussion on the comparison of the arts) the letters did not discuss issues of aesthetics.

In some cases, the letters documented true friendships between the correspondents and some artists (Cassiano dal Pozzo and Nicolas Poussin, Giovanni Battista Ricciardi and Salvator Rosa); more often the letters referred however to commissions, business transactions and differences of opinion on the orders, often revealing the dependence of the artist both from the taste and the power of the client, even if in different forms: Jacopo Guidi was in condition to dictate his conditions to the artists, because he decided the artists’ access to the Medici’s commissions; Ferrante Carlo, an unsuccessful poet who worked for cardinals first in some towns of the Po Valley and then in Rome, was not only an intermediary of Ludovico Carracci and Giovanni Lanfranco and other artists, but also their confidant; Cassiano dal Pozzo was a great intellectual who created - for reasons linked to his desire to document knowledge - one of the major libraries in Rome and, above all, a huge collection of prints (the Paper Museum), and had either more friendly or more formal relationships with several artists (including female artists, like Giovanna Garzoni and Artemisia Gentileschi). In short, the letters bore witness to what Bellori and Maratta had discussed in a pleasant way in the Dialogues: artists depend on the counterparts, both for good and for bad. Well, it is not surprising that the German translator of the letters in the mid-XIX Century, Ernst Guhl, saw in the missives above all an instrument to study the evolution of the relationship of power between artists and society and that many of the letters belonging to Bottari’s Raccolta were considered with great attention by scholars of art patronage such as Francis Haskell.

An important exception, in which clearly the work of Bottari had started from the archive of a sender, and not of a recipient, was represented by the twenty-one letters signed by Vincenzo Borghini (1515-1580), philologist, scholar and great friend of Giorgio Vasari, whom he helped both in the editing of the Lives and in the preparation of iconographic programs. The numerous texts actually revolved around a fifty-page letter of his (and, therefore, in fact more a report than a letter) addressed to the Grand Duke on the occasion of the wedding celebrations of Francesco I dei Medici with Johanna of Austria. Giovanni Gaetano added Borghini’s letters to many other artists (Vasari, Bronzino, Buontalenti, Caccini) engaged in the same festivities, in which Borghini revealed himself as a man of great inventiveness as an organizer of parties and proposed themes and solutions.


Parallelisms between Dialogues and Raccolta in the letters of Tuscan artists of the XVI Century

Considering the 'Florentine' section of the volume (roughly eighty letters), the parallels with the first of the five Dialogues were numerous. The letters of Michelangelo to Vasari documented the difficulties or even the impossibility of the great artist to convince the authorities about the goodness of his projects: Pope Julius III del Monte on the chapel for his family; Paul III Farnese on Saint Peter’s construction; Cosimo I dei Medici on a (later not used) project for the construction of the Church of San Giovanni dei Fiorentini in Rome. Similar were Michelangelo’s difficulties with colleagues like Bartolomeo Ammannati in the case of the staircase of the Laurentian Library in Florence. Compared to what was written in the Dialogues, the Raccolta added new episodes of incomprehension between Michelangelo and the papacy.

Obviously, the link was not simply univocal (from the Dialogues to the Raccolta). It is obvious that it is entirely legitimate to investigate the inverse relationship: if Bottari chose the theme of the dependence of artists from power as the focal point of the fictitious conversations in the Dialogues, it did it also because he was inspired by the misadventures witnessed in the Florentine letters he had consulted already for decades; after all, he put in the mouths of the two protagonists of the Dialogues the same words he was reading in the letters. It is therefore not surprising that the symmetry between Dialogues and Raccolta was particularly pronounced in the Tuscan section.


Parallelisms concerning the Emilian artists of the early XVII Century

The Raccolta of 1754 hosted forty letters from Emilian artists, with Ludovico Carracci (1555-1619) as the main protagonist. He signed sixteen letters to Ferrante Carlo (from 1608 to death) and received two letters from his own cousin Hannibal. Giovanni Lanfranco (1582-1647) also wrote to Ferrante with ten letters from 1636 to 1641. The presence of other Bolognese school painters such as Guido Reni (two letters), Guercino (1591-1666) and Lavinia Fontana (1552-1614) was smaller.

On the left and in the center, in the Dialogues on the three arts of drawing (with quotations from Malvasia and Bellori). On the right, in the Collection of letters on painting, sculpture, and architecture.


Here too there were parallels: we have already said that the Bolognese art entered in the Dialogues in the second fictional conversation between Bellori and Maratta, and then became predominant in the fourth dialogue, when the quotes from Vasari's Lives were first placed side by side and then replaced (in extension and intensity) by those taken from Malvasia’s Felsina Pittrice. In short, the two works defined the same chronological sequence of artistic literature, which saw Bologna (Malvasia and letters of Carracci / Lanfranco and others) as the new art centre after Florence.

In line with the same themes already dealt with respect to Florentine artists, in the Dialogues the two fictitious interlocutors exchanged information on the cases in which the Bolognese were victims of commercial exploitation, and spent a lot of time in particular on Domenico Zampieri, known as Domenichino (1581-1641). They recounted in detail the case of the chapel and dome of San Gennaro in Naples, which was documented in numerous passages of the Dialogues with a quote from Malvasia [63] and one from Bellori [64]. It is by far the worst case of exploitation documented by Bottari: the frescoes in the Chapel of the Treasure of San Gennaro were made by Domenichino under the threat of local painters, who even forced him to escape; in the story told by Malvasia and Bellori, the Bolognese painter died of a broken heart in Naples because he had been replaced by Lanfranco, after his frescoes had been covered with lime. The case returned in the Raccolta: in a letter dated 23 January 1632 and addressed to Cassiano del Pozzo, the painter himself informed the scholar about the unfair conditions imposed to him for the execution of those Neapolitan works [65].

The opposite situation was that of the Bolognese engraver and painter Giovanni Valesio (1579 - 1650), who was described in the Dialogues as the prototype of an incompetent taking advantage of the ignorance of the clients (specifically the Dominican Fathers in Bologna, who prefer him to Tiarini). I do not think it is a coincidence that the Raccolta included a letter from Valesio to Ferrante Carlo (in itself completely devoid of content): it offered an opportunity to talk about Valesio in both texts.


The letters of the Baroque artists working in Rome and Naples

The last eighty letters of 1754’s Raccolta were dedicated to the Baroque, and among them sixty were received by Cassiano dal Pozzo (1588-1657). In the introduction to the Raccolta Giovanni Gaetano thanked Cardinal Albani for placing at his disposal Cassiano’s library and papers: "I still have to give due praise to the most eminent Mr. Cardinal Alessandro Albani, possessor, and high expert of the rarest antiquities, and lover and promoter with all his strengths of the three fine arts, who kindly authorised me to extract from his copious library all those letters, which I would find appropriate, and which he owned in the books of the already famous Cassiano del Pozzo” [66].

Cassiano’s correspondents included Nicolas Poussin (1594-1665) with twenty-three letters concentrated between 1641 and 1642, Artemisia Gentileschi (1593-1654) with six letters between 1630 and 1637, Pietro da Cortona (1596-1669) with six letters between 1641 and 1646 and finally Pietro Testa (1612-1650) with three letters between 1632 and 1637. There were also missives by lesser-known artists, such as the miniaturist Giovanna Garzoni (1600-1670) with four letters from 1630-1631 or artisans today practically forgotten, like the Augustinian Father Giovani Saliano, whose date of birth and death are unknown. Implicitly, the Raccolta thus offered a coherent idea of ​​the Roman Baroque art, based on the network of knowledge and aesthetic preferences of a single protagonist (who clearly preferred a baroque style of classicism).

The only case relevant to this period, outside Cassiano’s correspondence, was that of the 16 letters sent by Salvator Rosa (1615-1673) to the aforementioned Giovanni Battista Ricciardi. In the Dialogues he was considered an erratic but brilliant artist (the source from which Bottari drew on his personality was Baldinucci).


What was missing in 1754’s Raccolta compared to the Dialogues?

If we consider the content of the Dialogues as an expression of Bottari's taste (and therefore as a paradigm of good taste), what was missing in the Raccolta published the same year? Evidently, the architecture's coverage in the collection of letters had a much reduced coverage compared to the long fictitious conversations on it between Poussin and Maratta. Some of the 'masters of painting', such as Guido Reni, were underrepresented: in the Dialogues Reni was exalted as the greatest artist of all time, in the Raccolta he was present with only two letters (one, very short, to an unknown interlocutor [67] and the other to Count Bolognese Count Antonio Galeazzo Fibbia, in which he discussed exclusively monetary aspects). And obviously there were no living artists, those with whom Giovanni Bottari might have had personal acquaintance.

Did these gaps perhaps solicit the continuation of the work? We will see it in the third part of this post.
