The target audience of natural history was French polite society, evidenced more by the specific discourse of the genre than by the generally high prices of its works. Naturalists catered to polite society's desire for erudition many texts had an explicit instructive purpose. However, natural history was often a political affair. As E. C. Spary writes, the classifications used by naturalists "slipped between the natural world and the social ... to establish not only the expertise of the naturalists over the natural, but also the dominance of the natural over the social". The idea of taste (le gout) was a social indicator: to truly be able to categorize nature, one had to have the proper taste, an ability of discretion shared by all members of polite society. In this way natural history spread many of the scientific developments of the time, but also provided a new source of legitimacy for the dominant class. From this basis, naturalists could then develop their own social ideals based on their scientific works.

By the end of the regal period Rome had developed into a city-state, with a large plebeian, artisan class excluded from the old patrician gentes and from the state priesthoods. The city had commercial and political treaties with its neighbours; according to tradition, Rome's Etruscan connections established a temple to Minerva on the predominantly plebeian Aventine; she became part of a new Capitoline triad of Jupiter, Juno and Minerva, installed in a Capitoline temple, built in an Etruscan style and dedicated in a new September festival, Epulum Jovis. These are supposedly the first Roman deities whose images were adorned, as if noble guests, at their own inaugural banquet.
At the end of the regal period, what class was kept out of the state political and priesthood arenas?
