The skeletal image shown in this article is from a dig at Balathal in Rajasthan. It was taken by Dr. Vasant Shinde of the Department of Archaeology at Deccan College and dated by Dr. Gwen Robbins to the 6th cen BCE. I reference this image and dig in an article on the roots of samādhi burial coming out in the spring issue of Oxford Journal of Hindu Studies. The issue itself is part of a special double issue on samādhis, tombs, and relics co-edited by Brian Hatcher, Abhishek Amar and myself.
