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.
Daemon is the Latin word for the Ancient Greek daimon (δαίμων: "god", "godlike", "power", "fate"), which originally referred to a lesser deity or guiding spirit such as the daemons of ancient Greek religion and mythology and of later Hellenistic religion and philosophy.
The word is derived from Proto-Indo-European *daimon "provider, divider (of fortunes or destinies)," from the root *da- "to divide". Daimons were possibly seen as the souls of men of the golden age acting as tutelary deities, according to entry δαίμων at Liddell & Scott.
