The minber dates from 1400, and was carved by Antepli Hacı Mehmed bin Abdulâziz el Dukki, a renowned woodcarver from Gaziantep (on the Syro-Turkish border). His name is mentioned in one of the inscriptions on the pulpit. Sultan Yıldırım Beyazıt knew about him, because this artist had carved (in 1376) another marvelous pulpit for the Ulu Cami in Manisa, the capital of the Saruhanlı Principality, that Beyazıt conquered in 1390.
This minber is made of walnut that has been darkened with black paint. It is a splendid example of the transition from late-Seljuk style to early-Ottoman.
The ‘kündekari’ technique has been used: pieces of different sizes are worked separately, and then assembled (like a big jigsaw puzzle), without using any glue, split pin or nail. This technique is extremely difficult.
