King of the Fairies, whose wife was Titania. Shakespeare introduces both O'beron and Titania, in his Midsummer Night's Dream. (Auberon, anciently Alberon, German Alberich, king of the elves.)
O'beron the Fay.
A humpty dwarf only three feet high, but of angelic face, lord and king of Mommur. He told Sir Huon his pedigree, which certainly is very romantic. The lady of the Hidden Isle (Cephalonia) married Neptanebus, King of Egypt, by whom she had a son called Alexander the Great. Seven hundred years later Julius Caesar, on his way to Thessaly, stopped in Cephalonia, and the same lady, falling in love with him, had in time another son, and that son was Oberon. At his birth the fairies bestowed their gifts—one was insight into men's thoughts, and another was the power of transporting himself to any place instantaneously. He became a friend to Huon (q.v.
), whom he made his successor in the kingdom of Mommur. In the fulness of time, falling asleep in death, legions of angels conveyed his soul to Paradise. (Huon de Bordeaux
, a romance.)
