The Ancient Greek: δαίμων, pronounced daimon or daemon, originally referred to a lesser deity or guiding spirit such as the daimons of ancient Greek religion and mythology and of later Hellenistic religion and philosophy.
The word is derived from Proto-Indo-European daimon "provider, divider ," 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. See also daimonic: a religious, philosophical, literary and psychological concept.
