2000 year old tradition. Read some poetic drops from Sangam Literature on Jallikattu.
We would have had numerous chances to make fun of Ramarajan taming the wild bull in Jallikattu with Illayraja’s pechi pechi song. It was a cult it. But even more surprising was a reference in Kalithokai of angry elephant (usually in rut – Madha yanai) which couldnt be controlled by its gad (pagan) getting mellow down and tamed with music of harp (yaazh).
