This canard was first challenged by Marshall Hodgson in The Venture of Islam(1974). He believes that the brilliant works, in architecture, philosophy, andthe visual arts, created during the sixteenth century-in Isphahan, Istanbul,Delhi and Agra-were not inferior to the masterpieces of the Italian Renaissance.
The scientific work did not face sudden death either. In fact, George Saliba, inA History of Arabic Astronomy, extends Islam's golden age to thefifteenth century. After the Mongols are supposed to have devastated EasternIslam, major observatories were being set up as late as the fifteenth century.The astronomical tables computed at these observatories, together with the workof Ibn-Shatir (d. 1375), a time-keeper in the central mosque of Damascus, werepassed on to Europe, and are believed to have contributed to the Copernicanrevolution.
