Rare first edition – printed on blue paper – of this treatise by the Venetian physician Giovanni Calderia, possibly composed in 1457, and posthumously edited by Michelangelo Biondo, author of Della nobilissima pittura (see no. 108). The edition is dedicated by him to Francesco Donà.
Calderia wrote the Concordantiae Poetarum Philosophorum et Theologorum for his beloved daughter Cateruzza, in order to remove her from her excited religiousness: in fact, in 1451, Guarino Veronese's son asked for Cateruzza's hand in marriage but the pious sentiment of the girl, supported by her mother, caused the negotiations to fail. The work guaranteed to its author a certain reputation as a Platonic philosopher during the subsequent centuries.
This copy offered here was once owned by one of the greatest collectors of blue paper books: Raoul Chandon de Briailles, who may have purchased it from the library of Andrea Tessier, sold in Munich in 1900 by the bookseller Jacques Rosenthal, which contained a copy “tiré sur papier bleu” (lot 519, in the section “Particularités. Imprimées sur vélin, sur papier bleu. Elzevier non rognés. Minuscules etc”).
