In Greek mythology, Echidna (also spelled “Ekhidna” or “Ekhidne”) was a fearsome monster, known as the “Mother of all monsters” and one of the children of the primordial sea gods, Ceto and Phorcys. She was half woman and half serpent, and was said to dwell in a cave in the wilderness. Echidna was said to be the mother of many famous monsters such as the Nemean Lion, Cerberus, the Hydra, the Sphinx, and the Chimera.

Echidna’s story is often seen as a symbol of the dangers and mysteries of the wild, and the power of the ancient monsters that ruled over it. She was also seen as a representation of the unknown and the fear of the unknown. In addition, Echidna’s story has been retold in various literary works and art forms over the centuries, and has been interpreted in different ways.
