The flag of Sicily shows a triskeles symbol, and at its center a Gorgoneion with a pair of wings and three wheat ears.
In the original flag, the wheat ears did not exist and the colors were reversed. The original flag was created in 1282 during the rebellion of the Sicilian Vespers.

A triskelion or triskeles is an ancient motif consisting either of a triple spiral exhibiting rotational symmetry or of other patterns in triplicate that emanate from a common center.
The spiral design can be based on interlocking Archimedean spirals, or represent three bent human legs. It occurs in artifacts of the European Neolithic and Bronze Ages with continuation into the Iron Age – especially in the context of the La Tène culture and of related Celtic traditions.
The actual triskeles symbol of three human legs is found especially in Greek antiquity, beginning in archaic pottery and continued in coinage of the classical period.
