Which historical artist helps Ezio Auditore in Assassin's Creed II?

Leonardo da Vinci helps Ezio Auditore in Assassin's Creed II.

Leonardo is portrayed as a close friend and inventive ally of Ezio. He deciphers pages from Altaïr's Codex and uses his engineering skills to improve Ezio's equipment. His workshop becomes an important resource as Ezio's journey moves through Renaissance Italy.

The game uses real historical figures within a fictional conspiracy narrative. Leonardo's appearances are set before and during his better-known period of artistic and scientific activity, and the game presents a dramatized relationship between him and Ezio rather than a documented historical friendship.

Leonardo also designs a flying machine that Ezio uses during a mission in Venice. Michelangelo, Raphael, and Botticelli were also major Renaissance artists, but they are not the artist who serves as Ezio's principal inventor and technical ally in Assassin's Creed II.
