Dumézil maintains that Jupiter is not himself a god of war and agriculture, although his actions and interest may extend to these spheres of human endeavour. His view is based on the methodological assumption that the chief criterion for studying a god's nature is not to consider his field of action, but the quality, method and features of his action. Consequently, the analysis of the type of action performed by Jupiter in the domains in which he operates indicates that Jupiter is a sovereign god who may act in the field of politics (as well as agriculture and war) in his capacity as such, i.e. in a way and with the features proper to a king. Sovereignty is expressed through the two aspects of absolute, magic power (epitomised and represented by the Vedic god Varuna) and lawful right (by the Vedic god Mitra). However, sovereignty permits action in every field; otherwise, it would lose its essential quality. As a further proof, Dumézil cites the story of Tullus Hostilius (the most belligerent of the Roman kings), who was killed by Jupiter with a lightning bolt (indicating that he did not enjoy the god's favour). Varro's definition of Jupiter as the god who has under his jurisdiction the full expression of every being (penes Iovem sunt summa) reflects the sovereign nature of the god, as opposed to the jurisdiction of Janus (god of passages and change) on their beginning (penes Ianum sunt prima).Varro apud Augustine De Civitate Dei VII 9.
