Drakaina (mythology)
In Greek mythology, a drakaina is a female serpent or dragon, sometimes with humanlike features.Mythology
Examples of the drakaina included Campe, Delphyne, Echidna and Sybaris.
Python, slain by Apollo, and the earliest representations of Delphyne are shown as simply gigantic serpents, similar to other Greek dragons. However, although the word "drakaina" is literally the feminine form of drakon, most drakainas had some features of a human woman. Lamia, Campe, Echidna, and many representations of Ceto, Scylla and Delphyne had the head and torso of a woman.
The drakaina was a monster generally slain only by gods or demigods. Zeus slew Delphyne and Campe, Apollo slew Python, and Argus Panoptes slew Echidna.
Echidna was the mate of Typhon and the mother of a huge brood of monsters, including other dragon-like creatures. According to Hesiod, Echidna gave birth to Cerberus, Orthrus, the Chimera, the Nemean lion, the Sphinx and the Hydra.
