The GaulishtheonymMātr-on-ā signifies "great mother", and the goddess of the Marne has been interpreted to be a mother goddess. Many Gaulish religious images—including inexpensive terracottas mass-produced for use in household shrines—depict mother goddesses nursing babies and/or holding fruits, other foods, or small dogs in their laps. In many areas, such Matronae were depicted in groups of three (or sometimes two) (see Matres and Matronae for the triads of mother-goddesses well attested throughout northern Europe).
The name of Welsh mythological figure Modron, mother of Mabon is derived from the same etymon. By analogy, Dea Matrona may conceivably have been considered the mother of the Gaulish Maponos.
