This is a reconstructed portion of a full suit of armor (krug) that a soldier of the Ottoman Empire would have worn into battle. The chain mail that links the circular breast- and backplates to the steel plates at the sides and shoulders would have continued down over the warrior's forearms and connected with plate coverings that provided further protection from elbow to wrist. (The leather straps are modern replacements for sections of mail.) The soldier also might have been equipped with plate leg guards or with a long skirt or trousers made of mail and reinforced with additional steel plates.
The decoration of the plates features floral motifs, Arabic inscriptions (on the back) and interlaced patterns-decorative elements used throughout the history of Islamic art. Cropped and edited from the original image.
