Tropical Topographies: Mapping the Malarial in The Calcutta Chromosome

Abstract

This paper reads colonial archives of malaria in conjunction with Amitav Ghosh’s futuristic medical thriller The Calcutta Chromosome (1995) and contends that the novel, loosely based on Sir Roland Ross, ruptures narratives of colonial expertise. The colonial expertise on malaria is embodied by Ross, an officer in the Indian Medical Service; this is in contrast with the model of expertise proposed by the novel. While Ross’s expertise is predicated on the domination of nature and controlling diseased tropical landscapes, the novel resists imperial strategies of mapping and disease control. This paper argues that The Calcutta Chromosome presents an alternative attempt to map the malarial, rewriting history by displacing actors such as Ross and instead placing two colonial subjects, Murugan and Mangala, at the centre of new mapping practices. The novel further questions the notion of ‘colonial improvement’ which malaria facilitated in imperial regimes. Deviating from the colonial history of improving the native body and landscape as a cure for malaria, the novel foregrounds subjugated subjects working at the peripheries of laboratories and scientific practices and thus subverts the notion of the ‘improved subject’ by proposing the idea of the mutational, transformational ‘Calcutta chromosome.’
