In Assassin's Creed II, which Renaissance artist helps Ezio by designing a flying machine?

Leonardo da Vinci helps Ezio by designing a flying machine in Assassin's Creed II.

Leonardo appears as Ezio Auditore's friend, inventor, and technical adviser. He deciphers pages from Altaïr's Codex and uses their designs to improve Ezio's equipment. His flying machine allows Ezio to cross Venice during a memorable story sequence.

The historical Leonardo da Vinci lived from 1452 to 1519 and was a painter, engineer, anatomist, and inventor. Assassin's Creed II places a fictional friendship with Ezio within the real cultural world of Renaissance Italy.

The game also features other famous artists, which can cause confusion. Michelangelo appears in the broader Ezio story, but Leonardo is the artist directly associated with the flying machine in Assassin's Creed II.
