Schilling and Capdeville counter that it is his function of presiding over the return to peace that gave Janus this epithet, as confirmed by his association on 30 March with Pax, Concordia and Salus, even though it is true that Janus as god of all beginnings presides also over that of war and is thus often called "belliger", bringer of war as well as "pacificus". This use is also discussed by Dumézil in various works concerning the armed nature of the "Mars qui praeest paci", the armed quality of the gods of the third function and the arms of the third function.
