Bandua is closely associated with Roman Mars and less frequently worshipped by women. The religious nature of Cosus had many similarities with that of Bandua. Bandua had a warlike character and a defender of local communities. The worship of these two gods do not overlap but rather complement each other, occupying practically the whole of the western territory of the Iberian Peninsula. Supporting the idea, no evidence has been found of any women worshipping at any of the monuments dedicated to Cosus. Cosus sites are found near settlements, such as in Sanfins and the settlement near A Coruña.
