Rig Veda III.16.1, dedicated to AGNI, says:
ayamaghniḥ suvīryasyeśe mahaḥ saubhaghasya | rāya īśe svapatyasya ghomata īśe vṛtrahathānām ||
The translation of this mantra by H.H. Wilson(P.12) is as follows:
This AGNI is the lord of heroism and of great good fortune; he is the lord of wealth comprising progeny and cattle; he is the Lord of slayers of VRITRA
In Rig Veda it was mentioned at many places that Indra eliminated VRITRA.
In the mantra in question, it was mentioned that AGNI was the Lord of slayers of VRITRA. Please note that it was mentioned as slayers of VRITRA and that AGNI was eulogised as Lord of slayers of VRITRA. In Rig Veda it was mentioned that VISHNU only assisted Indra in slaying VRITRA.
My questions are:
Who are the other slayers of VRITRA, other than INDRA?
Why was AGNI was eulogised as Lord of slayers of VRITRA?
