Question: what mythology are ogres from?
Answer: Ogre could possibly derive from the biblical Og, last of the giants (or from the Greek river god Oiagros, father of Orpheus). The word ogre came into wider usage in the works of Charles Perrault (1628–1703) or Marie-Catherine Jumelle de Berneville, Comtesse d' Aulnoy (1650–1705), both of whom were French authors.
