Donatello
Early life

Donatello was born in Florence, probably in 1386, based on his own later statement in his catasto tax declaration; he claimed to be 41 years old in July 1427. He was the son of Niccolò di Betto Bardi, who was a "wool-stretcher" (tiratore di lana) and member of the Florentine Arte della Lana, the wool workers guild, which probably provided a good income.

Donatello's actual surname was therefore Bardi, but if he was related to the well known Bardi family of bankers, it seems to have been rather distantly. The banker Bardis were still wealthy and powerful, despite the default of Edward III of England in 1345 having caused the failure of their bank. After Contessina de' Bardi married Cosimo de' Medici around 1415, any connection he had might still have been useful to Donatello. However, Donatello's father did have a connection with the powerful Buonaccorso Pitti, whose diary records a fight in Pisa in 1380 in which Niccolò intervened, giving Pitti's opponent a fatal blow.

Vasari's claim that Donatello was raised and educated in the house of the prominent Martelli family is probably baseless, and given for literary, even political reasons. They were certainly later keen patrons of Donatello, and also commissioned work from Vasari himself.
