Among the Corsiniana’s manuscript holdings is a parchment codex produced in Florence after 1487, closely connected to the circle of Lorenzo il Magnifico. It contains a work by Cristoforo Landino, the refined Tuscan intellectual who lived and worked at the Medici court: De Vera Nobilitate, a philosophical treatise presented as a dialogue between two imagined Greek characters conversing in the house of the Magnifico – a highly important and symbolic location for Florentine culture of the period. The exquisitely illuminated opening page is attributed by most scholars to the collaboration of the miniaturists Boccardino the Elder and Attavante degli Attavanti.
