The Fountain of Diana (Fontana di Diana) is in the center of Piazza Archimede in Syracuse on the east coast of Sicily. It is also known as the Fountain of Artemis, as the original Greek name for the Roman goddess Diana was Artemis. map
Diana is the goddess of the hunt, wild animals and wilderness, childbirth and virginity, and was often shown carrying a bow and arrow. She was the daughter of Zeus and twin sister of Apollo, the god of music, truth and prophecy.
The fountain was created by Giulio Moschetti in 1907 using reinforced concrete.
The fountain includes a triton and a mermaid with a child on her lap riding sea monsters, and also includes Arethusa and Alpheus (Diana is helping Arethusa to escape unwanted attention from Alpheus, who fell in love with her after seeing her bathing nude in a stream).
