Out of ten telhis (memorandum) copied in the Veliyyuddin mecmua, three are part of Koçi Bey’s treatise. According to Rhoads Murphey, the form and style of the telhis show that they may in great probability be attributed to Koçi Bey (Rhoads Murphey, “Dördüncü Sultan Murad’a sunulan yedi telhis”, VIII. Türk Tarih Kongresi, Ankara: 11-15 Ekim 1976. Kongreye sunulan bildiriler, vol. 2, Ankara 1981, 1096). At any rate, they are to be counted among a prolific production of memoranda by middle-rank clerks, some of which were indeed read by the Sultan, became verbatim Imperial orders or otherwise contributed to Murad’s actual policy.
