Gilt bronze head from the cult statue of Sulis Minerva. In localised Celtic polytheism practised in Britain, Sulis was the goddess of the thermal springs that still feed the spas at Bath - which the Romans called Aquae Sulis. Celtic deities often remained to the end associated with a specific place, often a cleft in the earth, a spring, pool or well. The romans were syncretic, linking local gods to their own and built a temple to Sulis Minerva in Bath. Roman Baths Museum.
