The remaining Greek scholars moved to Jundi Shapur. Jews joined them, as did a group of Christians called Nestorians, who had their own ancient and scholarly traditions. Persians added their voices, and one of their learned doctors set off for what is now India, to gather and translate the wisdom of the Hindus. The school created the very first teaching hospital in the world, a place where the sick were treated and young doctors learned their craft, as well as a fine observatory to track the heavens. At Jundi Shapur the best scholars west of China all gathered to think and study together. –Sugar Changed the World,
