Abstract
The article studies the library of Teofilo Calcagnini, a prominent member of Borso d’Este’s court in Ferrara. Calcagnini is already well-known as the person who commissioned the famous manuscript of the Decameron now in the Bodleian Library, MS Holkham misc. 49. On the basis of an investigation of heraldic and archival sources, the article attributes various extant manuscripts to Calcagnini as their commissioning patron but it also describes the connections he had with artistic projects in the Estense court, thus shedding new light on luxury book production in Ferrara in the 1460s.
