Bertani was a painter and architect from Mantua who worked with Giulio Romano from 1531. His first documented work is the exterior decoration of the Palazzina Paleoga in the Palazzo Ducale. He succeeded Giulio as the main architect in Mantua. His major commissions were at the Ducal Palace and in the Church of Santa Barbara.
