Papers of members of the Gondi family, dealing with numerous aspects of their private lives (including correspondence between family members and with other Florentine and French aristocrats; wills and dowries; and real estate dealings); public positions (including diplomatic correspondence with the grand-ducal administration and the French court); and economic activities (including financial documents related to the textile and silk trade; commercial agreements with the Florentine guilds; records of loans; and farm management transactions) for the years 1418-1753. The documents that comprise the collection are divided into three series, the first dedicated to papers of individual family members, the second to documents grouped by topic, and the third to filze, miscellanies primarily of business documents. The papers of individuals, arranged alphabetically by name, then chronologically for each person, comprise documents pertaining to about 30 different Gondi family members, the most important being the senator and ambassador Giovanbattista Gondi, the grand-ducal officer Lorenzo Gondi, and the bankers Giuliano and Antonio Gondi. The Subjects series, arranged alphabetically by subject, and chronologically within each subject, is comprised, for the most part, of numerous kinds of financial documents (including accounts, receipts, orders, payments, etc.) related to manufacturing, textile and silk trade, and other commercial activities; other miscellaneous documents are related to different aspects of rural life and farm management. The Filze series consists of four disbound miscellanies arranged alphabetically by the letter that appears on the original binding of the filza. Within each filza, the gatherings are arranged according to the order and page number in which they were bound. The Oversize series consists of larger items pertaining to various members of the Gondi family (such as Giovanbattista and Federigo Gondi) as well as documents that were previously bound with the filze.
