i'm not familiar with this source, but if you want something that's not me, this discusses an academic source that has traced greek influence on the development of buddhist thought.

i understand that buddhism traces itself to before alexander, and i don't dispute that, but the earliest actual writings we have were created during the period of hellenic influence and they really do seem to have a distinctively greek style to them. it's actually very easy to believe, without getting technical about it.
