Tomb of Ludovico il Moro and Beatrice d'Este, Pavia
Cristoforo Solari (c. 1460–1527), also known as il Gobbo (the hunchbacked), was an Italian sculptor and architect. He was the brother of the painter Andrea Solari.
Among his work, one of the most famous is the tomb of the dukes Ludovico il Moro and Beatrice d'Este for the Certosa di Pavia, carved between 1497 and 1499.
For a while people thought he had sculpted the Pietà, causing Michelangelo to break into the church and chisel his name on it.
