Mangala’s Cult and the Posthuman Body: Troubling Life, Death, and Human/Nonhuman Boundaries in "The Calcutta Chromosome"

Abstract

              This study examines how Amitav Ghosh’s "The Calcutta Chromosome" reconfigures the human body through Mangala’s subaltern scientific cult, positioning embodiment as a posthuman process rather than a fixed biological fact. In the novel, Mangala and her followers develop practices of bodily transfer that use malaria parasites, ritual, and secrecy to move consciousness between bodies, thereby challenging Western biomedical models that define the self as discrete, autonomous, and bounded by mortality. By reading Mangala’s experiments through posthumanist and new materialist frameworks, the paper argues that Ghosh disrupts the Enlightenment binaries of human/nonhuman, self/other, and life/death that underwrite colonial science. The analysis first situates Mangala’s work as “counter-science,” a subaltern epistemology that treats the "Plasmodium" parasite and the mosquito not as objects of study but as collaborators in knowledge production. Drawing on Rosi Braidotti’s concept of zoe and Stacy Alaimo’s trans-corporeality, it shows how Ghosh presents the human body as porous, entangled with microbial and nonhuman agencies that co-author identity and history. The cult’s manipulation of the “Calcutta chromosome” further illustrates a posthuman re-engineering of life itself, where immortality is achieved not through technological mastery but through inter-species symbiosis and ritual transfer. Second, the paper contrasts Mangala’s practice with Ronald Ross’s colonial malaria research to reveal competing ontologies of science. Whereas Ross’s Nobel-winning work depends on extracting knowledge from nonhuman nature, Mangala’s cult depends on becoming-with the parasite, dissolving the subject/object distinction. This contrast exposes how Western humanism secures its authority by denying agency to subaltern and nonhuman actors alike. Ultimately, the study contends that "The Calcutta Chromosome" theorizes a posthuman body that is multiple, transferable, and temporally non-linear. Mangala’s cult does not simply invert colonial science but proposes an alternative ethics of entanglement in which survival requires surrendering the fantasy of human exceptionalism. The novel thus anticipates contemporary Anthropocene concerns by suggesting that rethinking embodiment is essential to decolonizing knowledge and confronting ecological crisis.
