In Assassin's Creed II, which historical artist becomes Ezio Auditore's close ally?

Leonardo da Vinci becomes Ezio Auditore's close ally in Assassin's Creed II.

Ezio meets Leonardo in Florence, where the artist helps him understand and use pages from Altaïr's Codex. Leonardo's inventions and technical skills support Ezio throughout the game, including the development of equipment and the interpretation of ancient designs.

The historical Leonardo was a painter, engineer, inventor, anatomist, and theorist associated with the Italian Renaissance. Assassin's Creed II fictionalizes his relationship with Ezio but places him among real cities, rulers, artists, and political events.

The other names are also Renaissance artists, which makes them plausible distractors. Michelangelo appears in the broader Ezio trilogy, including Brotherhood, but Leonardo is the recurring inventor and confidant who works directly with Ezio in Assassin's Creed II.
