Architectural decoration

Early Islamic architecture is most original in its decoration. Mosaics and wall paintings followed the practices of antiquity and were primarily employed in Syria, Palestine, and Spain. Stone sculpture existed, but stucco sculpture, first limited to Iran, spread rapidly throughout the early Islamic world. Not only were stone or brick walls covered with large panels of stucco sculpture, but this technique was used for sculpture in the round in the Umayyad palaces of Qaṣr al-Ḥayr West and Khirbat al-Mafjar. The latter was a comparatively short-lived technique, although it produced some of the few instances of monumental sculpture anywhere in the early Middle Ages. A variety of techniques borrowed from the industrial arts were used for architectural ornamentation. The mihrab wall of Kairouan’s Great Mosque, for example, was covered with ceramics, whereas fragments of decorative woodwork have been preserved in Jerusalem and Egypt.
