A collection of contracts involving Carlo Bernardo Alamanni de' Medici, most concerning property and goods, but many also concerning debts, sales, purchasing of titles, and inheritances. Some regard ecclesiastical properties. The title page (f. i recto) contains a later list of revised deeds, organized by year and page number, dated 1656. Divided into sections based on date, from 1552 to 1569. Most of the interactions and goods described are located near or in Florence. Many concern Giovanni Baptista Detti, Camillo de' Medici, Francisco from the ship Decumano, and a Bartolomeo. Many of the properties have been entrusted to Carlo de' Medici, who then rented them out. Details included about the various properties regard crops, houses, the kinds of trees on a property, barrels for wine, and so on. Last quire is detached from the rest of the codex. Contains marginal notes, mostly in Italian summarizing the Latin text, throughout, as well as a few notarial signets. Notaries include Franciscus de Jordanis (f. 14r), Joannes Baptiste de Jordanis (f. 14r), and Sebastian de Franceschis Vicchi (f. 15r).
