Mars Grabovius is the second member of the Grabovian triad of Iguvium, corresponding to the Roman Mars in his double character as god of war and of the protection of the fields and the community. In the lustration of the people he receives three oxen before the Tesenacan Gate. Alongside his martial aspect, the Iguvine cult also knows a closely related figure, Çerfus Martius ('the growth-god of Mars'), whose Çerfian deities frame the agrarian and apotropaic side of the same ritual complex. His shared epithet Grabovius binds him with Jupiter and Vofionus as the three gate-gods who guard the sacred circuit of the city.
