What is depicted on the national flag of Sicily?

The flag of Sicily (Sicilian: Bannera dâ Sicilia; Italian: Bandiera della Sicilia) shows a triskeles symbol (a figure of three legs arranged in rotational symmetry), and at its centre a Gorgoneion (depiction of the head of Medusa) and a pair of wings and three wheat ears.The flag is characterized by the presence of the triskeles in its middle, the (winged) head of Medusa and three wheat ears, representing the extreme fertility of the land of Sicily.

The triskelion symbol is said to represent the three capes (headlands or promontories of the island of Sicily), namely: Pelorus (Peloro, Tip of Faro, Messina: North-East); Pachynus (Passero, Syracuse: South); and Lilybæum (Lilibeo, Cape Boeo, Marsala: West), which form three points of a triangle from the historical three valli of the island.
