Medusa Graffiti Optical Illusion

In flags and emblems
The head of Medusa is featured on some regional symbols. One example is that of the flag and emblem of Sicily, together with the three legged trinacria. The inclusion of Medusa in the center implies the protection of the goddess Athena, who wore the Gorgon's likeness on her aegis. Another example is the coat of arms of Dohalice village in the Czech Republic.
