If you’ve traveled to Sicily, you’ve likely seen, on flags, ceramics and souvenirs, a strange-looking representation of a female head with three legs attached to it, flexed to form a triangle. That’s the symbol of Sicily, adopted by the island many centuries ago, when it was dominated by the Greeks, now used in the official Sicilian flag. The symbol is known as Trinacria, a Greek word that means ‘three pointed;’ it recalls the shape of the island, which resembles a triangle. Trinacria was the earliest known name of the island of Sicily.
The head refers to Greek mythology, it is said to be Medusa, a gorgon (monstrous creature) with a head of snakes, a beautiful woman seducing men who, upon looking at her, were turned into stone. In the past, it was customary to place a trinacria behind the home’s door as a symbol of protection for the house - the Medusa would have turned to stone whoever wanted to hurt the family living inside.
