↑ After much uncertainty, Piero's birth date was identified in the parish reconds of San Lorenzo by Dennis Geronimus, "The Birth Date, Early Life, and Career of Piero di Cosimo", The Art Bulletin 82.1 (March 2000:164-170); Geronimus was able to rely on the consistency of Lorenzo di Piero d'Antonio's reports of his children's ages at the catasti of 1469 and 1480, and a new database of Florentine baptismal records.
