Moving on to the Cizre Ulu Mosque Door Wings and Knocker from the Artuklu Period in the 13th century, the door, adorned with bronze plates on a wooden frame, is ornamented with three medallions on each wing, featuring a twelve-pointed star at the center. The intricate geometric design, extending to the edges of the door, creates an impression of infinite continuation. The bronze relief inscription in thuluth calligraphy on the wings reads "May God give strength to Ebul Kasim Mahmud Sencer Shah."
A special feature of the collection is the presence of a knocker that is part of the double-winged door of the Cizre Ulu Mosque, with the other identical knocker being housed at the David Samling Museum in Copenhagen, following its theft in 1969. The mallet of the knocker, crafted through casting and adorned with intricate engravings, consists of a composition of two dragons and a lion head at the center, displaying pointed ears, almond eyes, and wings. The bodies of the dragons, covered with snake scales, are entwined in a spiral form, while their tails culminate in the shape of an eagle's head. It is believed that these mallets were designed based on drawings by Cezeri, adding an engaging historical context to these exceptional artifacts.
