Florence, trial records, 18 December, 1517, 5 November, 17 November, 24 November, 1 December 1518.  Related to Rosso’s indebtedness to the Florentine citizen, Jacopo di Leonardo da Colle.  Unfortunately, as Franklin (1987, 659, and 662, Appendix B; and 1994, 52) pointed out, we do not know from these documents why Rosso owed this money, nor who Jacopo di Leonardo da Colle was.
