Over time gods or, groups of gods might be consolidated or split, and it is unclear that there were ever any strict separations of all function. The sovereign function (1) embodied in Jupiter entailed omnipotence; thence, a domain extended over every aspect of nature and life. The three functions are interrelated with one another, overlapping to some extent; the sovereign function, although including a part that is essentially religious in nature, is involved in many ways in areas pertaining to the other two.
