In the Surva Siddhanta is contained a system of trigonometry which not only goes beyond anything known to the Greeks, but involves theorem which were… - Mountstuart Elphinstone in India, 1796-1818

Lord Mountstuart Elphinstone (1779-1859) in comparing the ancient Greeks with the ancient Hindus, says: "Their (Hindus) general learning was more considerable; and in the knowledge of the being and nature of God, they were already in possession of a light which was but faintly perceived even by the loftiest intellects in the best days of Athens."

The common origin of the Sanscrit language with those of the west leaves no doubt that there was once a connection between the nations by whom they are used; but it proves nothing regarding the place where such a connection subsisted, nor about the time, (…) To say that it spread from a central point is a gratuitous assumption.

It is opposed to their foreign origin, that neither in the code of Manu nor I believe in the Vedas, nor in any book that is certainly older than the code, is there any allusion to a prior residence or to a knowledge of more than the name of any country out of India. Even mythology goes no further than the Himalayan chain in which is fixed, the habitation of Gods. It is unthinkable and beyond all canons of logic and common sense that the Hindus had forgotten their original home even at the time of the composition of the earliest Vedas. Christians look to Jerusalem for the origin of their religion, Muslims to Arabia, and Jews to Palestine, but the Hindus have all their sacred places within India itself. If they really had come from outside India, they should have some place of pilgrimage like Mecca or Benares. "To say that it (emigration) spread from a central point is a gratuitous presumption and even contrary to analogy for emigration and civilization have not spread in a circle but from east to west."
