One of my favorite things to do is research Islamic history. I thought I'd share:


The foundation of this legacy was the astonishing achievements of Muslim scholars, scientists, craftsmen, and traders during the two hundred years or so that are called the Golden Age. During this period, from 750 to 950, the territory of the Muslim Empire encompassed present-day Iran, Syria, Iraq, Egypt, Palestine, North Africa, Spain, and parts of Turkey and drew to Baghdad peoples of all those lands in an unparalleled cross-fertilization of once isolated intellectual traditions.

Unlike the Byzantines, with their suspicion of classical science and philosophy, the Muslims were enjoined by the Prophet to "seek learning as far as China" - as, eventually, they did. In the eighth century, however, they had a more convenient source: the works of Greek scientists stored in libraries in Constantinople and other centers of the Byzantine empire. In the ninth century the Caliph al-Mamun, son of the famous Harun al-Rashid, began to tap that invaluable source. With the approval of the Byzantine emperor, he dispatched scholars to select and bring back to Baghdad Greek scientific manuscripts for translation into Arabic at Bayt al-Hikmah, "the House of Wisdom."
