(b Florence, c. 1380–85; d Florence, 1421). Italian sculptor. His father, Antonio di Banco (d 1415), a stone-carver at Florence Cathedral with whom he trained, was married in 1368, which provides a terminus post quem for Nanni’s birth. On 2 February 1405 Nanni matriculated in the Arte di Pietra e Legname, the masons’ guild, presumably to allow him into the cathedral workshops. He is first documented there on 31 December 1407, working with his father on the archivolt sculpture of the Porta della Mandorla.
