The French-language Malagasy texts by Rakotoson, Raharimanana and Ravaloson depict the underside of the earth through the image of characters being buried in mines or under waste. But they also evoke other under ground spaces : caves, underground water... How can an ecopoetics of the deep help us understand the recurrence of these buried places ? The underworld, as a space of exploitation and catabasis, seems far from the « deep » that Glissant defines as « that which, from below, links together all the here » . Howerever, the underside can become the deep when a « reso nance » occurs, one that lies in the concrete experience a subject has with the place. The underworld is then no longer to be conceived as a resource to be exploited – which condemns it to silence – nor as a mystical depth – which condemns the resonance to being only internal – but can then establish a concrete and « responsive » Relation with the subjects and between the worlds.
