Echidna
A half-woman, half-serpent monster mother whose offspring in Hesiod lead toward later heroic trials.

Overview
Echidna stands near the centre of Hesiod’s monster genealogy as a mother of later terrors, not as one isolated creature defeated in a single exploit. Through her line, figures such as Cerberus, the Hydra and the Chimaera become part of a connected monster tradition that later heroes must face. Pseudo-Apollodorus also preserves a parentage in which Gaia and Tartarus produce her, tying Echidna to earth, depth and the old powers beneath heroic adventure. Her importance is genealogical: she explains how primordial danger becomes a family of monsters.
