In Celtic mythology, Dea Matrona was the goddess of the river Marne in Gaul. In many areas she was worshipped as a triple goddess, and known as Deae Matres, with a wider sphere of believed[who?] influence. This triadic deity is well attested throughout northern Europe, not just in Celtic areas, and was similar to the Fates, Furies, Norns, and other such figures. The Gaulish theonym M tr-on- is interpreted to mean "great mother". The name of Welsh mythological figure Modron, mother of Mabon is derived from the same etymon.
