Aswatahama [written aswathama in IndiaLIT]
do you know Aswa: horse in present day usage in India and uma: horse in present day usage in Japan.
Is it possible Aswa-t-uma [aswa-bat-uma=an aswa like a uma] points to a hi-breed of two kinds of horses?

It can also [from how its pronunciated be said like aswa to uma aswa and uma].

So I guess it does not prove that such hi-breeds were there 2000 yrs ago [or as Indian myth lovers would say 5000 years ago] but possible that it was so 300-800 or more years ago. Because myth has a way of entering 50 years ago and claiming 500 years ago. Its myth. Its mythya [=false in Indian, and my etymoana says ya denotes "in relation to" in Indian/sancrit]. In-fact in Sancrit [I am not writing sanscrit] ja/ya/ia are variants from degradation [one linguistic insight is when degradation ]
