Mid 16th century. Ottoman. Jeweled and gold-inlaid steel. Flower motifs were even used on armor, such as this jewel encrusted helmet thought to date from the reign of Suleyman the Magnificent, the tenth and longest-reigning Sultan of the Ottoman Empire, from 1520 to his death in 1566. Each of the rubies and turquoises is set in a flower-shaped gold mount.
