Collection of 42 letters and documents written to Piero Chiarini (sometimes referred to as Pietro or Perugino) from various members of the Chiarini family between 1390 and 1399. The senders include Piero's great-uncle, Marco, from Florence; Piero's father, Bernardo, his uncle Bartolomeo, and his brother Antonio, who were all residing in Split (referred to as Spalato, a mostly independent city in Croatia, with a strong presence of Italian migrants); Piero's brother-in-law Rosso di Andreozzo (also referred to as de Orlandi), who lived in Florence but also spent time in Padua; and many personal or family friends of Piero, including Pietro Paolo de' Gualdi, Archdeacon of Split; Lorenzo di Pacino; and others. Most of the letters contain brief exchanges of information concerning family matters, with some short passages dedicated to business and political affairs. The tone of the correspondence is always informal and affectionate, and sometimes also nostalgic or melancholic, for example when they discuss the death of a relative, Brother Angelo Chiarini (letter no. 33, written in Latin). Two legal documents in Latin (no. 7-8) are powers of attorney concerning Piero Chiarini and his wife Elisabetta Baldasari. References to many other family members and friends are also frequent, as well as numerous details of everyday life in the Chiarini households around Italy and in Croatia. 2 letters are crossed out (no. 62, no. 176). Front flyleaf is made of modern paper with title Spalato in pencil.
