The frontispiece of the fine 15th-century Ottoman manuscript Sulayman-Name. At the top sits Prophet Sulayman, known as King Solomon to Christians. Around and below him are attendants, soldiers, and even monsters. Sulayman wears the costume of an Ottoman sultan. The fifth row depicts the Prophet-King's army. Two officers carry maces, one flanged, the other a transitional Turkish animal-headed style. (T 406, f.1b. Chester Beatty Library, Dublin)

A reversed image of the seated Ottoman soldiers is referenced on p.16, Armies of the Ottoman Turks, 1300-1774 by David Nicolle & Angus McBride This panel from a manuscript of c.1500 is probably the oldest existing Muslim representation of Ottoman warriors. Made in Bursa for Bayezit II, it shows sipahi troopers wearing helmets, mail aventails, and in some cases, apparent armour over their feet. (Sulayman-namah Ms. 406, F.1V.
