Leonardo da Vinci

"Ezio! So good to see you! How can I help you?."

- Leonardo's greeting to Ezio

Leonardo di ser Piero, better known as Leonardo da Vinci (April 15, 1452 – May 2, 1519) was an Italian polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, botanist and writer in the Italian Renaissance. He is generally considered the most talented person who ever lived.

Trivia

 * All of Leonardo's modifications on previously existing assassin gear are designs created by Altaïr. Leonardo just follows the designs detailed in Altaïr's codex, which only he and Giovanni Auditore can decipher and translate. It is probably from these that da Vinci designed some of his other inventions. Perhaps Ezio allowed Leonardo to experiment with the Apple himself, giving birth to some of his other inventions.
 * Like other main characters, Leonardo's appearance does not change throughout the 23 years he is shown in the game, from his first encounter to the decoding of the the Codex in the villa in 1499.
 * Unless it is a Codex page or something important to the story, such as the design for two hidden blades, the cutscene is the same when Ezio visits Leonardo each time (even after Leonardo moves to Venice).
 * Leonardo's last name isn't actually da Vinci, he was adopted by a prostitute (courtesan), and Vinci being the town he was born in, he took on the name Leonardo da Vinci (meaning Leonardo of Vinci).
 * According to the database, Leonardo was most likely homosexual, and his apprentice, a boy he nicknamed Salai ("little Satan"), was likely his lover.
 * Ironically, in Dan Brown's book The Da Vinci Code, it is speculated that Leonardo da Vinci was the Grand Master of a secret society known as The Priory of Sion, an organization that was alleged to have Templar connections.
 * Also ironically Leonardo would later become a close friend and military engineer for Cesare Borgia, son of Rodrigo Borgia.
 * In AC II's first DLC, the Battle of Forlì, Leonardo was resistent to the Piece of Eden's powers, like the Assassins.
