The essay examines the way F. Anstey s A Fallen Idol (1886) and Richard Marsh s The Mahatma s Pupil (1893) dramatise the relationship between a Tibetan Theosophical mahatma and a western disciple through the use of cartographic imagery that ultimately subverts colonial hierarchies and exposes western religious anxieties. The novels are characterised by a "cartography of the supernatural" that derives from nineteenth-century scientific and occult ideas of spatiality, that is, both from new fin-de-siècle communication technologies connecting the mainland with colonies, and from the contemporary radical theorisation of occult communication between the east and the west. I argue that the novels effect a radical socio-political restructuration by building on this underlying cartographic imaginary to achieve subversive spatial re-mappings for a western audience. A crucial aspect of this narrative manoeuvre can be seen in the way the novels establish a parallel between the disciple s spatial bafflement surrounding the geographical remoteness of Theosophy and the western failure at grasping the spiritual depths of this colonial faith. The novels therefore ultimately offer a commentary on the desiccated state of western religiosity and the alternative templates of the miraculous offered by the colonial occult. © 2019 Victorian Popular Fiction Association.
