Because it functions as the focal point in prayer ritual, its decoration was and continues to be executed with great skill and devotion.Examples:Iran, Mihrab from the Madrasa Imami in Isfahan, 755 AH / c. 1354 CE, mosaic of monochrome-glaze tiles on composite body set on plaster, 11 feet 3 inches x 7 feet 6 inches (343.1 x 288.7 cm), Metropolitan Museum of Art, NY.Egypt, Cairo, Mihrab and Minbar of the Mosque of Sultan Hasan, 1356-1360.
