Meaning of the Name
Senuna was a Celtic Goddess worshipped in Roman Britain. Her name appears in various forms on the votive plaques, namely Senuna, Sena and Senua, that were discovered 2002 in an excavation. Conceivably it might be related to the Proto-Celtic *seno- ‘old’.
She may have been a water Goddess local to the region. Perhaps she presided over a sacred spring or was a river Goddess.
The name Senua was possibly wrongly attributed by River Senua mentioned in the Ravenna Cosmography.
