Kaluyan

Kaluyan, called Kaluyan al-Qunawi in Arabic sources, was an architect active in medieval central Anatolia. His name appears on the Köşkmedrese near Kayseri, the khanqah built in 1339 by Eretna in memory of his consort Suli Pasha; he may have been Armenian.

Turkish tradition also credits him with major Seljuk buildings, including the Gök Medrese at Sivas. He is said to have been born a Christian and a follower of the Sufi poet Rumi before converting to Islam.
