ezioauditore-s:BOTTEGA DI LEONARDO (1499-1506) In 1499, after being forcibly recruited by the Papal Captain General Cesare Borgia, Leonardo began to design and create weapons and war machines for the Borgia forces. As such, by 1500, he had relocated his workshop to Rome. He remained there even after Cesare’s fall from power, and in 1506, Leonardo spent much of his time in his workshop studying Pythagoras and the Pythagorean temple, as well as working on his latest painting, the Mona Lisa. -- source link
