I was reminded of Al Beruni the Iranian scholar from the ninth century. Al Beruni had visited India and was a known Sanskrit scholar. He had written one of the most comprehensive books on india of that period - Tarikh al-Hind that roughly translates to Chronicles of India. He had also translated some mathematical work by Indian mathematicians.Indian mathematics made its way to europe through the arabs and the persians. Globalization of science!!!
