04The myths

3 myths, each traced to its primary text and corpus sources.

Echidna joined with Typhon and bore a brood of monsters. Typhon was an enormous hybrid with prodigious strength. He had a hundred serpent heads, dark tongues, fiery eyes, and voices that sounded like many kinds of animals. In some tellings, serpents formed his feet and hair. Poison-spitting bristles covered him, and countless arms extended from his body. Echidna was described as a creature with the form of a beautiful woman above and a serpent below, and she lived in a cave.

Their brood included Cerberus, the three-headed hound of the Underworld, and Orthrus, the two-headed hound of Geryon. They also bore the Hydra, a many-headed water-serpent that lived at Lerna. The Chimaera had a lion’s head, a goat’s body, and a serpent’s body. It breathed fire. The lion, goat, and serpent also marked the three parts of the year, with each creature representing one season.

In one telling, Orthrus later lay with Echidna, his own mother, and fathered the Sphinx and the Nemean Lion. In another telling, Orthrus also fathered the Chimaera and the Hydra on Echidna. This gave the monstrous brood another set of family ties, while Cerberus remained the hound most closely linked with the Underworld.

The Dorians linked Cerberus with the dog-headed Egyptian god Anubis, who conducted souls to the Underworld. Another telling made Cerberus an earlier form of the death-goddess Hecate or Hecabe, who took the form of a bitch because dogs ate the flesh of corpses and howled at the Moon. Other tellings gave Echidna and Typhon further monstrous offspring, including the Caucasian Eagle, Ladon, and the Crommyonian Sow. The brood therefore extended beyond the hounds, serpents, and fire-breathing Chimaera.

  3. 3Greek Mythology – August 2018T1

Echidna emerged as a serpent woman, with the upper body of a maiden and the lower body of a snake. One telling placed her in a cave. A description called her partly lovely despite her monstrous nature. Another tradition made her larger and more savage than her mother, the original serpent woman Ceto.

Hesiod named Phorcys and Ceto as Echidna’s parents. They were sea deities. Other genealogies named Tartarus and Gaia, or Chrysaor and Callirrhoe. Some tellings made Echidna the wife of Typhon. Together, Echidna and Typhon produced a dreadful brood. Their children included Cerberus, the three-headed hound of the Underworld, Orthrus, the two-headed hound of Geryon, the Hydra of Lerna and the Chimaera, a fire-breathing creature with a lion’s head, a goat’s body and a serpent’s form.

Their offspring also included the Nemean Lion, the dragon of the Hesperides and the Colchian dragon. Other tellings added the Sphinx, Scylla, a Gorgon and the eagle that fed on Prometheus’ liver. The accounts differed over Orthrus. In one telling, Typhon and Echidna produced him, and he became Cerberus’s brother. In another, Orthrus lay with Echidna and fathered the Sphinx and the Nemean Lion.

Echidna treated Cerberus tenderly as her pup, and he adored her. Typhon threatened to kill his latest offspring, but he knew what Echidna could do when angered. He left after warning that he would never return. Echidna had heard such threats for a hundred years and expected to hear them for a hundred more. Cerberus was born with three heads. Hades admired the monstrous family and sent gifts whenever one of Echidna’s eggs hatched. The brood continued to emerge from Echidna and Typhon.

  3. 3War in Greek MythologyT1

Travellers passing through the Arimoi came within reach of Echidna, who lived in a cave and seized those who went by. She devoured them there. Apollodorus names her as the daughter of Tartaros and Ge, and says that she made a practice of snatching away passers-by. Her death came when Argus found her asleep.

Argus was the son of Agenor and the grandson of Ecbasos. He was called Panoptes, or All-Seeing, because eyes covered his body. He also possessed exceptional strength. Before facing Echidna, he had killed the bull that was bringing ruin to Arcadia and had worn its hide. When a Satyr mistreated the Arcadians and stole their cattle, Argus confronted and killed him. He later avenged the death of Apis by killing those responsible.

Argus watched Echidna and waited until she was asleep. He then killed her in the cave. The account presents the killing as an act of vigilance against the creature who had been taking travellers from the road. It does not describe a contest between them while she was awake. Echidna was destroyed when Argus found the moment at which she could not resist him.
