Bonanno Pisano (Pisa), active in the 1170s and 1180s, was an Italian sculptor, mixing Byzantine and classical elements. Giorgio Vasari wrongly attributed the realisation of the Leaning Tower of Pisa to him in his Vite. Pisano was born in Pisa and worked there most of his life. In the 1180s, he departed for Monreale, in Sicily, where he completed the doors to the cathedral before returning to Pisa, where he died. Pisano was buried at the foot of the leaning tower, where his sarcophagus was discovered in 1820.
