Sirona is a Celtic goddess worshipped in Gaul; she was frequently accompanied by a consort, most often Grannus (Apollo Grannus). She was often associated with sacred springs and healing waters and was honored at a number of shrines and temples.
Depictions of Sirona in art indicate that she is also a goddess concerned with fertility: she has been shown carrying eggs, wheat and fruit. She is often shown with a snake, which may reflect her status as a healer.
Sirona was worshipped at numerous temples and shrines, where she received votive and dedicatory offerings. Otherwise little is known of the specifics of her cult.
Several different origins have been suggested for the name “Sirona.” It may have been derived from the Proto-Celtic *ster- or “star”; it may also have come from the older Proto-Indo-European *sti-, a word with uncertain watery connotations; finally, the Proto-Indo-European *ster- or “heifer” is a possibility. I have most often seen the “star” interpretation, although there is no direct connection between that and her known attributes.
Tribal and other associations
Sirona was extremely popular among the Treveri, whose territories were centered in the modern city of Trier in Germany, and included what is now Luxembourg, as well as portions of Belgium and Germany. However, she was not strictly a tribal goddess and was honored well beyond that region, including within territories of numerous other tribes.
While Sirona’s worship was particularly common in the territories of the Treveri and in north-eastern Gaul, she was worshipped far and wide; her shrines appaear as far east as Hungary.
