Arc Silt Dive is about the work of Sheba Chhachhi; it maps her methods, the modes of address and inquiry in her photographs, animated lightboxes, videos and installations. Translating the rich immersive experience of multidimensional installations into flat images, prose text and verbal description was a challenge. Yet this change of medium need not be reductive; rather, it may be seen as a bound moment in the peripatetic trajectory of installations which are frequently reworked and retested at different sites, and face new formal and contextual dilemmas in each. The artworks reproduced in the book are not sequenced chronologically; rather, following arcs of connectivity and unexpected conjunction, they are reclustered thematically and visually, re-installed along some of their own overlaps, intersections or displacements. The installations convey a sense of recursive reflection in the circulation of images, concepts, concerns, in which little seems to be permanently abandoned and much is reworked, often in technological mediums falling into market-induced obsolescence.
