Abbot of Amboise
From Tardis Wiki, the free Doctor Who reference
The Abbot of Amboise was the right-hand man of the Cardinal of Lorraine, religious leader of the Catholics in France, and strongly anti-Huguenot. He was a member of the conspiracy to assassinate Admiral Gaspard de Coligny. When the plan failed, Marshal Gaspard de Saux-Tavannes blamed him for it and had him executed. His death was blamed on Huguenots.
The Abbot was a physical double of the Doctor, and Steven initially thought that the Abbot was the Doctor in disguise. (DW: The Massacre of St Bartholomew's Eve)
