salamander

At Satan's Ball Margarita sees a salamander-magician who was not burning in the fireplace. In medieval lore salamanders were thought to survive fires.

Some considered the salamander to be like Christ, because he passed through the fires of hell unharmed.

Another interesting connection: the fireproof salamander was the symbol of the French King François I, who was the grandfather of Marguerite de Valois and the brother of Marguerite de Navarre!
