Cerberus

In Greek mythology, Cerberus is the guardian of Hades and is usually described as a bizarre looking monster that looks like a dog with three heads and a tail whose end is a dragon s head. According to the ancient tragedian Aeschylus, Cerberus was born from the union of two monsters, the giant Typhon and Echidna, which would make Cerberus brother of the Lernaean Hydra. Cerberus is not considered an evil creature that hurts people intentionally, but a creature that ensures the arrival of the dead to the underworld and prevents the living from entering Hades. Cerberus is also often described in myth as one of the most loyal guards in history and is often mentioned in Homer s epics.
