Mog Ruith
Legendary Irish magician from Munster, who was linked in Ireland to biblical and apocryphal traditions, notably as a pupil under Simon Magus and as one responsible for the beheading of John the Baptist. He appears in Irish genealogies as a descendant of Medb and her lover Fergus mac Roích and as an ancestor for Fir Maige Féine, in the area about present-day Fermoy.
