Mabon Ap Modron

Mabon ap Modron is a prominent figure from Welsh literature and mythology, the son of Modron and a member of Arthur's war band. Both he and his mother were likely deities in origin, descending from a divine mother–son pair. His name is related to the Romano-British god Maponos, whose name means "divine son"; Modron, in turn, is likely related to the Gaulish goddess Dea Matrona. He is often equated with the Demetian hero Pryderi fab Pwyll, and may be associated with the minor Arthurian character Mabon fab Mellt.
