Although early reviewers of Edwin Abbott’s Flatland recognized the novel as a fictional travelogue, the travelogue aspect of the novel remains underexamined. This essay examines Flatland as a travelogue and as a work of ethnographic criticism in relation to the emergence of Victorian anthropology as a science. Situating Flatland in relation to the emergence of Victorian anthropology as a science and in relation to Notes and Queries on Anthropology, For the Use of Travellers and Residents in Uncivilized Lands (1874)—in particular to its concerns with the dangers of cultural assumptions—provides a means of tackling the problem both early reviewers and more recent scholars have noted concerning the marked differences between the novel’s two parts and the difficulties of making sense of the novel as a whole.
