The Colchian dragon, known as Drakôn Kolkhikos (Greek: Δρακων Κολχικος). This immense serpent, a child of Typhon and Echidna, guarded the Golden Fleece at Colchis. It was said to never sleep, rest, or lower its vigilance. According to Ovid's Metamorphoses, the monster had a crest and three tongues. When Jason went to retrieve the Fleece, the witch Medea put the dragon to sleep with her magic and drugs, or perhaps Orpheus lulled it to sleep with his lyre. Afterwards, Medea herself had dragons pull her chariot.
