Which historical artist designs Leonardo's flying machine in Assassin's Creed II?

Leonardo da Vinci designs the flying machine used by Ezio in Assassin's Creed II.

In the game's Renaissance setting, Leonardo is Ezio Auditore's friend, inventor, and technical adviser. He studies Codex pages associated with Altaïr and creates or improves equipment that helps Ezio, including the flying machine used during a mission over Venice.

The machine is fictionalized for gameplay, but it draws on Leonardo's genuine interest in flight. His surviving notebooks contain studies of wings, air, and mechanical devices, although no working human-carrying aircraft is known to have been built by him. The game turns that historical interest into a playable sequence.

Leonardo's role is broader than the flying-machine mission. He helps decipher Codex pages, maintains Ezio's equipment, and provides context for the advanced designs hidden in the manuscripts. The character therefore connects real Renaissance science and art with the series' fictional First Civilization technology.
