Building Baghdad

Damascus, Baghdad and Cordoba were not built out of enthusiasm. They were built out of specific, removable ingredients — a language of administration, a supply of Greek texts, Syriac translators, Persian bureaucracy, Indian numerals, cheap paper, and someone willing to pay. Switch them on and off and see which books get written. Then watch the sting: the arrangements that let the caliph govern an empire are the ones that eventually take it away from him.
