Taranit, Taranis

"In Celtic mythology, Taranis is the god of thunder, who was worshipped primarily in Gaul and Hispania but also in the Rhineland and Danube regions, amongst others. . . Many representations of a bearded god with a thunderbolt in one hand and a wheel in the other have been recovered from Gaul, where this deity apparently came to be syncretised with Jupiter."
