Another example of luxury objects being employed to ease diplomatic relations is at the court of Badr al-Din Lu’lu’, an Armenian convert to Islam. He was a Zangid vizier, and then an independent ruler of Mosul in Northern Iraq from 615–57 / 1218–59. Badr al-Din Lu’lu’ took a great interest in inlaid metalwork. A number of brass vessels inlaid with gold and silver and bearing his name survive. These valuable vessels were probably used as a replacement for gold and the fact that Lu’lu’ has included his name on them is testimony to their function as ambassadorial gifts.
