Records say that this Festival Indra Vizha was introduced by an early Chola King Thodithol Chola at the behest of Sage Agastya.

I had shown Sage Agastya’s date to be around 5000 years earlier, based on the movement of Star Canopus, Agastya Nakshatra.

I shall write more on the antiquity of Tamil Kings.

The Cholas lineage is from the Puranic times and the Cholas were related to Virata Kings( Currently the area is Rajasthan).
