The arithmetic book of Filippo Calandri (original title: Trattato di aritmetica ) is an arithmetic book for merchants, which was printed in 1491. A richly illustrated codex of this arithmetic book, handwritten on parchment , is now kept in the Biblioteca Riccardiana in Florence .

The work

The trattato was commissioned for Lorenzo il Magnifico , who wanted his son Giovanni to be trained in commerce and especially in banking, which the Medici operated in Florence and far beyond its walls. Giovanni later became Pope Leo X.

The manuscript of the Biblioteca Riccardiana ( Ricc. 2669 ) consists of 122 sheets; his numerous miniatures and jewelry come from the workshop of Giovanni Boccardo, known as Boccardino Vècchio (1460–1529), an Italian illuminator who later also worked for Pope Leo X.

The manuscript does not name an author. Your attribution was based on the incunabulum , which was printed in Florence by Lorenzo Morgiani and Johannes Petri and is dated January 1, 1491-92. The print includes a reference to the manuscript and is dedicated to Giovanni de Medici.
