References to India occur in Greek writings (and Alexander came all the way to its borders), an Indian system of medicine is called Yunani (from Ionian), and so forth, but these are not the oldest contacts with India: Indians were already trading with the Sumerians some millenium and a half before Alexander (though, of course, they were not called Indians then).
