"Mitra (1822-91) is famous for his publications on Orissan antiquities (1875, 1880), Bodh Gaya (1878) and a two-volume collection of essays (1881) dealing with different aspects of material life in ancient India. In his Odisha volumes he strongly advocated the independent origin of Indian stone architecture and earned the wrath of James Fergusson, the most established architectural historian of India of that time. In the volume on Bodh Gaya he argued for the existence of true arch in an early context in the Mahabodhi temple, and among his essays on the ancient Indian material life he cited copious data on beef- eating and the practice of spirituous drinking in ancient India."
