The name of the steel, however, is a reference to the city of Damascus, the capital of Syria, where the swords were either sold or directly forged at some time in the past. mysteries of wootz. There are numerous early literary references to steel from India from Mediterranean sources including one from the time of Alexander (3rd c.
