Which Renaissance artist creates inventions for Ezio in Assassin's Creed II?

Leonardo da Vinci creates inventions for Ezio in Assassin's Creed II.

In the game, Leonardo is portrayed as a friend and technical ally of Ezio Auditore. He helps interpret pages from the Codex left by Altaïr and develops equipment based on the designs. His workshop becomes an important place in Ezio's travels through Renaissance Italy.

The game uses Leonardo's real historical reputation as a painter, engineer, anatomist, and inventor. It also presents fictionalized versions of ideas associated with him, including a flying machine that Ezio uses during a mission in Venice.

Leonardo should not be confused with the game's other famous Renaissance figures. Michelangelo is represented in the Florence setting, while Machiavelli becomes a major Assassin ally. The story freely dramatizes history, so the character's interactions with Ezio are fictional rather than documented events.
