 One Western scholar claims that, in the Vedas, the epithet 'hero' ("sura") is itself almost exclusively reserved for "Indra", while in the Avesta it is applied to "Thraetaona" and other non-divine figures.The term "victorious" is not restricted to "Verethragna", but is also a property of a number of other figures, both divine and mortal, including "Thraetaona".Then, while in the Vedas it is "Indra" who discovers Soma, in the Avesta it is humans who first press Haoma and "Thraetaona" is attributed with being the "inventor of medicine".
