The third and revised Valgrisi edition of Boccaccio's masterpiece, lavishly illustrated, and edited for the Venetian printing house by Girolamo Ruscelli (ca. 1518-1566). The first Decameron from the press of Valgrisi – the famous printer of French origin, active in Venice from 1540 'all'insegna d'Erasmo' – had appeared in 1552, and was intended to rival the successful Giolito editions. The work is supplemented by Ruscelli's Vocabolario generale di tutte le voci usate dal Boccaccio, while the preliminary leaves contain, as an introduction, La vita di messer Giouan Boccaccio, written by Francesco Sansovino (1521-1586). The Valgrisi Decameron is one the finest editions of Boccaccio's work produced in the sixteenth century and is rightly famous for its handsome full-page illustrations introducing each giornata, all newly designed and mentioned – as “figure nuoue & bellissime” – on the title-page. Each woodcut is framed within an architectural border including putti, grotesque figures, antique vases, and floral motifs, and depict scenes from the life at the villa of the brigata of young men and women who had fled from Florence during the plague. The success of the publication was immediate, and Valgrisi re-issued Boccaccio's work in 1554, 1555, and 1557, thereby establishing a new iconography of the Decameron in print. The blocks and borders were later re-used by other Venetian printers, including Agostino Zoppino, Onofrio Farri, and Alessandro Vecchi.
The Valgrisi Decameron presented here is in a fine contemporary French binding. The covers bear at the centre the device of three interlaced crescents, a feature which might suggest the binding was executed for Diane de Poitiers (1499-1566), mistress of King Henry II of France and from 1548 duchess of Valentinois, who used the triple-crescent device. The exquisite library assembled by this femme bibliophile remained in her Château d'Anet until its sale in 1724. For a similar binding on a copy of Cardanus's De subtilitate (1561) see The Michel Wittock Collection. Part I: Important Renaissance Bookbindings, lot 30. It is noticeable that the crescents also appear on bindings from the King's own library.
