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 "Great 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.
