Gorgons

    The Gorgons were a trio of monsters in Greek mythology. They were sisters who were legendary for their horrible faces (and bodies), and ancient Greek artists seemed especially fond of depicting the Gorgons as grotesque creatures. And because of their terrifying appearance and abilities, these mythic monsters were the perfect beings to play evil enemy to a host of Greek heroes.
    One of our best primary sources for information about the Gorgons comes from the Theogony of Hesiod. In this poem that describes the birth of the Greek gods and goddesses, we learn that the Gorgons were the daughters of Phorcys and Ceto.
    So from this passage in the Theogony, we know that the Gorgons were the sisters of the Graiae; that they lived in the far West; that they were named Stheno, Euryale, and Medusa; and that two of the sisters - Stheno and Euryale - were immortal, while the third - Medusa - was mortal and therefore could be killed (and indeed, Medusa, as the sole mortal sister, is most famous in mythology for the story of her tragic life and death).
    As was previously mentioned, the Gorgons are also notorious for their distinctive appearance. According to ancient Greek artists, these monsters were not just ugly - they were hideous. The Gorgons are commonly portrayed in ancient art with snakes for hair, enormous tongues, teeth that would make a boar blush with envy, and a stare that could literally petrify. However, it is also worth noting that in some versions of the myth of the Gorgons, Medusa is described as a beautiful woman who makes the unfortunate mistake of comparing her beauty to that of the goddess Athena - see the page about Medusa for more details.
