Rosmerta was a Celtic goddess of fertility and abundance, her attributes being those of plenty such as the cornucopia.
She was often depicted with Mercury as her consort, but is sometimes found independently. Twenty-seven inscriptions to Rosmerta have been found distributed in France, Germany and Luxembourg, corresponding mainly to the Roman provinces of Gallia Belgica and Germania Superior. An additional two inscriptions are known, one from Roman Dacia.
