Mythical creatures and monsters
Orthos
In Greek mythology, Orthos represents the two-headed dog. He was the son of the giant Typhon and Echinda.
Orthos lived on the island of Erytheia (near present-day Gibraltar), where he and the giant Eurythion protected the herds of the giant Géryonēs. But when the hero Héraklés arrived on the island, they were unable to protect the herds. Héraklés was ordered by the Mycenaean king Eurystheus to steal the entire herd on the island and kill all its guards, including Géryonēs. And he succeeded.
Orthos had several siblings, who were Kerberos (a three-headed dog), Chimera (a monster with the body of a lion, the middle of a goat and the back of a dragon, which breathed fire with three mouths), Sphinx (a monster with the head and chest of a naked woman, the body of a lion, the tail of a snake and the wings of an eagle) and Hydra (a monster with the body of a snake and nine dragon heads).
