Biography
Little is known about him, the inscriptions of the Tower of San Pancrazio and the Tower of the Elephant of Cagliari, where he's defined Architector optimus, are the only direct sources available. For Dionigi Scano it was of Sardinian origin, being his surname often found "in the toponymy and topography" of Sardinia. According to Salvatore Rattu he was specifically from Cagliari.On the other hand, his training as an architect is clearer, which is certainly Tuscan, as evidenced by the style of his works.
