The growing literature on the Indian Ocean in historical perspective is thick with accounts and interpretations of trade, routes, circulations of material objects, people, and ideas. There is even the notion of a Carceral (colonial) Indian Ocean, as in Clare Anderson's work. Though distinctly religious issues have hardly been neglected - after all, various inter-linked Islamic networks have arguably first constructed the space of the Indian Ocean almost as it now stands - it is all the same interesting to note that they are mostly relegated to a special domain. Namely, the ocean would be first and foremost that historically constructed via trade, material objects, people, routes, colonial and other networks. Ideas of course also circulate in the oceanic space, but they do not per se constitute it.
