Fonds contains a volume of receipts for various supplies received by the financial official of the cathedral chapter of Pisa, the monastery of San Lorenzo, and by other religious houses and individuals. The volume was begun by Captain Antonio Fantoni.
Fonds consists of contemporary manuscript copies of various legal records and instruments relating to the Capacci family. Includes one manuscript written on parchment in pale brown ink, ruled in pale brown ink, and bound in full contemporary blind tooled calf with laid paper endpapers and remnants of ties on covers, as well as a smaller booklet, written on parchment glued into a laid paper wrapper. Documents appear to be dated between 1556 and 1583 and are written in Latin and Italian (sometimes alternating within document). The legal instruments appear chiefly related to the dowry of Orietta Capacci (the dowry is also referenced in an Italian note in a later hand (1650?) inside front cover). Some names found throughout the documents include Orietta Capacci (or Orietta de Capacci) and Annibale (or Anibal) Camillo de Capacci.
