This article discusses how women’s travels in the early imperial period threatened the ‘natural’ socio-cultural hierarchy of the Roman upper-classes. In a first part, the main threads of the ideological discourse on female mobility will be mapped by means of an examination of a senatorial debate during the reign of Tiberius in Tacitus’ Annals, uncovering layers of meaning that have remained unnoticed. The second and third parts will be devoted to literary motifs that have shaped the characterizations of men and (...) women travellers to illustrate the extents to which Roman travel is gendered. Central to this examination is the Roman elite’s fear of the corrupting and disrupting power of the exotica of foreign nations and its effects on men’s and women’s Romanness. (shrink)
