( fl 1419–35). Italian sculptor. He was the son of a Fra Bartolo. From 1419 to 1424 he worked on various figures for the façade and campanile of Florence Cathedral. In July 1419, with Pietro Uberti Baldassarre degli Albizzi as his guarantor, he was commissioned to sculpt a figure for the cathedral façade, which was completed in March 1420. Its subject is not stated, but it may perhaps be identified as the St John the Baptist (Florence, Mus. Opera Duomo). On 30 April 1420 Nanni was asked to complete a statue of Joshua begun by Bernardo Ciuffagni in 1415 for the east side of the campanile. The identity of this figure is uncertain.
