The German journal London und Paris called James Gillray 'the foremost living artist in his genre, not only amongst Englishmen, but amongst all European nations'. Despite the scholarly attention he has attracted, many of Gillray's individual works have yet to receive rigorous analysis. One such neglected print is National Conveniences (1796), assumed to be a crude, straightforward expression of national supremacy. However, a closer reading shows Gillray employing the ideas of Jean-Jacques Rousseau both to undermine notions of English superiority and to assail a particular personal adversary. With this reading in mind, we can reassess references to Rousseau in Gillray's other prints, and propose a new direction from which to approach his greater oeuvre.
