rosmerta
In Gaulish Celtic mythology, Rosmerta was the goddess of fire, warmth, and abundance. A flower queen and hater of marriage, Rosmerta was also the queen of death. A Celtic goddess of fertility and wealth, whose cult was widely spread in Northeast Gaul. Rosmerta was the wife of Esus, the Gaulish Hermes. Her attributes are a cornucopia and a stick with two snakes.
The name is Gaulish, and is analysed as ro-smert-a. Smert means ‘provider’ or ‘carer’ and is also found in other Gaulish names such as Ad-smerio, Smertu-litani, Smerius, ΣμεÏο, Smertae, Smertus, etc. (Delmarre p.277). Ro- is a modifier meaning ‘very’ ‘great’ or ‘most’ as found in Ro-bili (‘most-good’), Ro-cabalus (‘great horse’), Ρο-βιος (‘great life’) (Delmarre pp. 261-2). The -a ending is the typical Gaulish feminine singular nominative. The meaning is thus ‘the Great Provider’ and this accords well with her attributes.
