Andrea da Pisa (Andrea Pisano)
sculptor and architect ; b. 1270; d. 1349.
He received his training in Pisa, Italy, probably from Giovanni da Pisa. Before going to Florence Andrea worked in Venice, where he is supposed to have assisted in the decoration of the Church of S. Marco and the Doge's palace. The only work which can with certainty be ascribed to him is the first bronze door which was made for the Florentine Baptistery between 1330 and 1336. At the death of Giotto, in 1337, Andrea was appointed architect of the Campanile and built the two stories of niches above the work of Giotto. From 1347 to 1349 he was chief architect of the Cathedral of Orvieto. The beautiful reliefs of the "Genesis" on the fašade of that building are supposed to show his influence.
Campedroni was born in the island of Majorca (Spain), and learned sculpture from his father Francisco. In 1330 he was appointed chief sculptor of the decoration of the cathedral of Palma (Majorca).
