Four Wooden Roundels

wood, carved in champlevé, with gilt inscriptions on painted ground, over a layer of gesso

diameter 60cm

Ottoman mosque architecture was dominated
 by central domes, the pendentives of which
 often bore roundels, of painted wood or tilework,
 with the names of God, Muhammad, Abu Bakr,
 ‘Uthman, ‘Umar and ‘Ali, and sometimes the 
names of Hasan and Husayn too, and appropriate 
prayers for each. The most famous, and the
 largest, are those designed by the 19th-century 
calligrapher, Mustafa ‘Izzet in the mosque of
 Ayasofya (converted from the great Byzantine
 church of Hagia Sophia) in Istanbul.

The four roundels in the Khalili Collection are inscribed with the names of God (MXD 265a), Abu Bakr (MXD 265b), ‘Uthman (MXD 265c) and Hasan (MXD 265d).
