Blacas ewer
The Blacas ewer is a brass ewer, inlaid with silver and copper, made by an esteemed man, Shuja' ibn Man'a al-Mawsili in Mosul in April or May 1232 (Rajab, 629 AH). One of the most important and well-known pieces of metalwork from Mosul, it was likely commissioned for Badr al-Din Lu'lu', who was already the de facto ruler of Mosul when the ewer was made and who officially became ruler one year later. Until 1997, the Blacas ewer was the only known piece of metalwork with an inscription explicitly saying it was made in Mosul.: 12 : 23 Because of this inscription, it forms one of the core items of the contested "Mosul School" of metalwork, since its Mosuli provenance is undisputed.: 23, 30
