Stheno and Euryale

In Greek mythology, Stheno (/ˈsθiːnoʊ/ or /ˈsθɛnoʊ/; Greek: Σθενώ, translit. Sthenṓ, lit. "forceful") and Euryale (/jʊəˈraɪəli/ yoor-EYE-ə-lee; Ancient Greek: Εὐρυάλη, romanized: Euryálē, lit. 'far-roaming') were two of the three Gorgons, along with Medusa, sisters who were able to turn anyone who looked at them to stone. When Perseus beheaded Medusa, the two Gorgons pursued him but were unable to catch him.
