Andrea (c.1290–c.1348) and Nino, his son (died c.1368), Italian sculptors. Andrea created the earliest pair of bronze doors for the baptistery at Florence (completed 1336). Nino was one of the earliest to specialize in free-standing life-size figures.
Two Italian sculptors, Nicola(c.1220–c.1278) and his son Giovanni(c.1250–c.1314). Nicola's work departed from medieval conventions and signalled a revival of interest in classical sculpture. His most famous works are the pulpits in the baptistery at Pisa and in Siena cathedral. Giovanni's works include the richly decorated facade of Siena cathedral.
