Can a word that's self-explanatory possibly be surprising? Turns out, in the case of "petroglyph" that literally translates to stone carving, there's so much to offer — and that too close to home.

Since the 1990s, locals in the Konkan spotted carvings on structures and viewed them as objects of worship or incorporated them in modern rituals. They, and the world at large, knew little about its significance until Maharashtra state government's department of archaeology and museums was alerted about it in 2017. And a talk at the Asiatic Society this evening by Dr Tejas Garge, the director of the body, will let you in on this adventure.
