The Chinese traveler Xuanzang (Hiuen Tsang) described a ritual organized by Emperor Shiladitya (identified with Harsha) at the confluence of two rivers, in the kingdom of Po-lo-ye-kia (identified with Prayaga). He also mentions that many hundreds took a bath at the confluence, to wash away their sins. According to some scholars, this is earliest surviving historical account of the Prayaga Kumbh Mela, which took place in Prayaga in 644 CE.
