Leonardo da Vinci

Leonardo da Vinci was an Italian Renaissance polymath known for his painting and inventions. The diary of the renegade Time Lord known as the Monk recorded a meeting with Leonardo in which he claimed to have provided the inspiration for at least some of da Vinci's inventions which would later seem so advanced for their time.

Circa 1505, da Vinci was hired by a new patron he knew as "Captain Tancredi", in reality, Scaroth of the Jagaroth. Tancredi asked him to paint six extra copies of his most famous work, the Mona Lisa. In 1505 the Doctor arrived from 1979 Paris to seek clues to the plot of Count Scarlioni (another of Scaroth's time-splintered selves) to steal the Mona Lisa from the Louvre. After being briefly captured and interrogated by Tancredi wrote "This is a fake" on Leonardo's canvasses in felt tip before returning to the future to try to stop Count Scarlioni.

 * Although the Doctor did not meet Leonardo in person in that period, he did leave him a note which suggested a degree of familiarity already existed, and that perhaps the two had previously met, or would meet in the future.
