Frederick III of Aragon, King of Sicily (1296–1337). Frederick III of Aragon was the third king of the Aragonese dynasty on the throne of Sicily. He ruled from 1296 to 1337 and he was the only Aragonese king of Sicily who made a significant use of his image. In particular, we have four official (namely, commissioned directly by him or his entourage) representations of him: the royal seal, the billon silver denaro coin, the lost mosaic from the Church of Santa Maria della Valle (known as Badiazza) near Messina, and the mosaic in the Cathedral of Messina.
