In Greek mythology, Echidna (; Greek: Ἔχιδνα, "She-Viper") was a monster, half-woman and half-snake, who lived alone in a cave. She was the mate of the fearsome monster Typhon and was the mother of many of the most famous monsters of Greek myth.
A sprite is a supernatural entity in European mythology. They are often depicted as fairy-like creatures or as an ethereal entity.
The word sprite is derived from the Latin spiritus ("spirit"), via the French esprit. Variations on the term include spright and the Celtic spriggan. The term is chiefly used with regard to elves and fairies in European folklore, and in modern English is rarely used in reference to spirits.
