PRAKASH JHA’s GangaaJal. And the odd put-down: "Nautanki mat karo". Those are virtually the only arenas where the folk theatre form survives today. With the last of the great performers on their way out, Nautanki is yet another indigenous art on the verge of getting lost. Reason enough for the chroniclers to uncap their pens and rescue some truly remarkable figures from oblivion. Figures like the late Gulab Bai, the first woman Nautanki artiste, and the only one to receive the Padmashree, in 1980. And through her, recreate the glory days of the art form that enraptured the rural populace long before cinema became a synonym for mass entertainment. ‘‘Gulab Bai was a pioneer,’’ says Delhi-based author, researcher and social activist Deepti Priya Mehrotra, 42. Her book, tentatively titled Gulab Bai: A Life in Nautanki, is scheduled to be published by Penguin later this year. Mehrotra first heard of the artiste while documenting an NGO play on Nautanki in 1997. ‘‘Gulab Bai had died the previous year and Tripurari Sharma, the director and playwright, kept referring to her,’’ says Mehrotra. She found a sponsor for her research in the Indian Foundation for Arts and now Gulab Bai is ready to reclaim her place in the sun.
