The Colchian dragon in Greek mythology was a fire-breathing giant serpent that guarded the Golden Fleece. The Golden Fleece was the prize the Greek hero Jason and his crew of Argonauts were after. With the help of the witch Medea, Jason managed to overcome the guarding monster and take the Fleece. It was put to sleep by the witch and it was left alone or slain by the hero. Dragons were common creatures in Greek mythology. Besides the Colchian dragon and Python, another famous monster was Ladon. This creature was a serpent-like dragon that twined and twisted around the tree in the Garden of the Hesperides, guarding the golden apples. According to one version of the myth, the monster was killed with a bow and arrow by Heracles when he came to collect the golden apples in his eleventh labor.
