 Hades with Cerberus - Pluto Carricci painting | Cerberus is a well known creature in ancient mythology. Hades’ loyal guard dog, Cerberus only had an appetite for living flesh and so would only allow dead spirits to pass, while consuming any living mortal who was foolish enough to come near. Cerberus was the offspring of the monsters Echidna and Typhon, and was usually described as having a serpent for a tail, and snakes protruding from his body.  |
 | Cerberus is best known as the twelfth and final labor of Heracles. Heracles must enter the underworld, wrestle the beast using no weapons, and then bring Cerberus to the surface world, alive, to present to the Mycenaean king Eurystheus. Although Eurystheus commanded him to bring back Cerberus, it was not from any desire to see Cerberus, but only because Eurystheus thought that the task was impossible. Heracles made his descent into the underworld through an entrance at Tainaron, the most famous of the various Greek entrances to the underworld. It took its name from the mythical son of Zeus, Taenarus, who built a town named Taenarum after himself. A cave network was believed to be an entrance to Hades. This gate was guarded by Cerberus, a beast that prevented the dead from escaping and the living from entering. |
 | Heracles tackled the beast, throws it over his shoulder and drags him to the mortal world. Upon seeing Cerberus, Eurystheus was so terrified that he hid in a large vase and begged Heracles to return the hell hound back to Hades. |  |
 | The domain of Hades in Greek mythology was not only hell, but was the whole of the afterlife. The realm was Tartarus (hell), the Asphodel Meadows (nothingness), and the Elysian Fields (paradise). |  |
