This talk will focus on the tale of the horse’s tour in Yudhisthira’s asvamedha (horse sacrifice) in book 14 of the Mahabharata, the first time such a literary project was attempted in Sanskrit literature. We look at how vedic ideas were reworked in the Mahabharata’s asvamedha. We also consider the actual journey the horse takes, which ultimately involves an approximate circumferencing of ‘India’. I shall suggest that while the Mahabharata makes use of the cosmology of the horse’s journey in the vedas, by giving the tour concrete geographic definition, the Mahabharata‘s horse sacrifice becomes a vehicle for a expressing the possibility of India as a potential sovereign unit. Again, this appears to be a peculiarly Mahabharata innovation that reflects the cultural ambitions of its authors.
