Sowmiya Ashok's book, 'The Dig,' explores the archaeological findings at Keeladi, a Sangam-era site in Tamil Nadu. The excavations, particularly carbon dating placing cultural deposits in the 6th century BCE, have been described as history-altering. The book situates these discoveries within India's contemporary political and cultural landscape, noting how Keeladi has become a symbol of pride and a point of contention amidst language and cultural debates.
