Many western people believe that David Pingree proved that Vedic Astrology came from Greece, without critically looking at why. Below, based on the Yavana Jataka notes of David Pingree, is a comparison of techniques found in the Sanskrit Yavana Jataka and other Greek/Latin Astrological Literature. The large amount of common Indian techniques in the Yavana Jataka not found anywhere in Greek or Latin sources does not prove anything came from Greece, but instead that Greece was a much later recipient of Classical Astrology from Babylonians, Egyptians and India.  The final argument that there are some Greek words in Indian texts, written at a time period when Greek was an international language and there was a large thriving Indo-Greek Kingdom in Afganistan does not prove Vedic culture sourced material from the Greeks over their Babylonian neighbors. The facts reveal themselves when you study the chart below which is based on Pingree's own notes to Yavana Jataka.
