1505

In 1505, the Fourth Doctor arrived at Leonardo da Vinci's studio from the year 1979 seeking clues to Count Scarlioni's plot to steal the Mona Lisa in that year. Leonardo, the Doctor discovered, was painting copies of his most famous work for his new patron, Captain Tancredi. He learned Scarlioni and Tancredi were temporal splinters of the same person, Scaroth, last of the Jagaroth. After being briefly captured and interrogated by Tancredi, the Doctor escaped back to 1979, after writing "This is a fake" on Leonardo's canvasses in felt tip (DW: City of Death).
