[1] In the Mahabharata, the sage Lomasha narrates the legend of the daityas called Ilvala and Vatapi to the prince Yudhishthira.
The elder of the brothers, Ilvala, is stated to have once begged a Brahmin hermit to grant him a son equal to that of the deity Indra.
He turned Vatapi into a lamb or a goat, cooked his meat, and served him to the Brahmin.
When Ilvala summoned Vatapi after being swallowed by the sage, the latter informed him that his brother had been digested by him.
[2][3] In the Ramayana, Ilvala is stated to have attacked Agastya after his brother's death, after which he was also slain by the sage's glance.
