Gorgons, Ancient G is a creature in Greek mythology. Gorgons occur in the earliest examples of Greek literature. While descriptions of Gorgons vary, the term most commonly refers to three sisters who are described as having hair made of living, venomous snakes and horrifying visages that turned those who beheld them to stone. Traditionally, two of the Gorgons, Stheno and Euryale, were immortal, but their sister Medusa was not[1] and was slain by the demigod and hero Perseus.
