From Puranas, we will come across incarnations of Vishnu, Shiva, etc.
I would like to know whether the Vedic God Indra took any incarnations, as per Rig Veda or commentaries on Rig Veda?
An extract from this book says that Rishi Savya was an incarnation of Indra.
Savya is the rishi in Rig Veda and Sama Veda. His Richas and mantras are collected in Rig Veda 1:51 - 57 and in Sama Veda 373,376 and 377. He belongs to Angirasa Gotra.
Acharya Sayana has explained that Savya was an incarnation of God of Gods Indra. So he is called Aindra.
Of the sage Angiras, who wished for a son like Indra, the bolt-bearer himself became the son, having assumed the form of Savya.
