Es-Seyyid Abdullah Efendi d. 1731
Abdullah of Yedikule was the favourite pupil of the celebrated calligrapher Hafiz Osman Efendi, and we know from the register of calligraphers that he received his icazet in 1102 H. He achieved great beauty and perfection in his use of Thuluth and Naskhi and was awarded both praise and protection by Sultan Ahmed Ill. He produced twenty-four Qur’ans as well as a number of Enams, Evrads, Kit’as, Murak’kas and Hilye-i Serifs. He had a large number of pupils. Most of his works are preserved in the Nuruosmaniye Library. Abdullah Effendi was greatly loved and admired by his teacher. He used the name Seyyid to indicate that he was descended from the family of the Prophet. He bid farewell to this transitory world in 1144 H.
