The dim but focussed lighting in a gallery choreographs a viewer’s ushering into an incremental conquest of secrets. Objects of long ago queue up for delight and heed; periods in history flow out of their temporal bounds; and the current-ness of a restored piece reminds us of shared responsibility. Conserving The Collection: 7 Years of ConservArte, an ongoing exhibition at Chhatrapati Shivaji Maharaj Vastu Sangrahalaya (CSMVS), touches on these intents while unspooling the philosophy of conservation — a modification on a relic should come undone in need. Watch the objects narrate the hows and whys of that process.
