Journalist and author Sowmiya Ashok’s new book, ‘The Dig: Keeladi and the Politics of India’s Past’, looks into the study of archaeology and history not just at that particular site but in today’s India as a whole, ranging from the methods used and the wide spectrum of people involved to the interpretations that can be both scientific and socio-cultural. She speaks to The Wire’s Jahnavi Sen about her research, why interpretations of history have become so contentious, and the findings at Keeladi.
