In Assassin's Creed II, which Renaissance inventor helps Ezio by providing weapons and equipment?

Leonardo da Vinci helps Ezio by providing weapons and equipment in Assassin's Creed II.

Leonardo is portrayed as Ezio's close friend and a brilliant inventor. He deciphers pages from Altaïr's Codex and uses the information to improve Ezio's gear, including the hidden blade and other tools. His workshop therefore connects Renaissance science and engineering with the Assassin conflict, while also giving the player access to important upgrades.

The historical Leonardo da Vinci was a painter, engineer, anatomist, architect, and inventor who lived from 1452 to 1519. Assassin's Creed II places him in real Italian cities and incorporates recognizable elements of his life, but the game fictionalizes his direct involvement with Ezio. Michelangelo and Raphael were also major Renaissance artists, yet neither performs Leonardo's equipment-maker role in the game.
