One of the most beautiful and enigmatic objects in the Courtauld Gallery's collection is the so-called "Courtauld wallet," a brass container richly inlaid with gold and silver, imitating a lady's textile or leather bag. Decorated all round with courtly figures and on the top with an elaborate banqueting scene featuring an enthroned couple, it has long been recognized as a masterpiece of Arab metalwork, probably made in Mosul in northern Iraq around 1300—yet no other object of this kind is known. This beautifully illustrated catalogue explores the origins, function, and iconography of this remarkable piece, as well as its cultural context. The essays here consider topics ranging from Mosul under Mongol governorship to music at the Mongol court, from Mongol marriage customs to the role of women under the Ilkhanids.
