Turkish Ottoman Helmet circa 1500 AD Gold and Silver Damascened with Arabic Calligraphy and stamped with famous St Eirene arsenal mark. These types of conical helmets were used by Mamelukes and Ottomans during the late 15th and early 16th century. A similar helmet was in the collection of the Hermitage Museum in St Petersburg crafted for the Sultan Basraby which is now in the Louvre in Paris. Another is in the present collection of the Hermitage in ST Petersburg 9INV.no.37,) and another similar type helmet is in the Nasser D.Khalili collection of Islamic Art published in the book ?The Arts of War? by David Alexander General Editor Julian Raby page 108 plate 55 Accession no.MTW 776. The visor of the helmet is attached by gold gilded copper rivets. The Helmet is rusty, the back of the helmet was probably smashed in combat, and on the front are four holes; the helmet requires professional restoration. This is a genuine gem for a serious collection. Measurements: Approximately 12 inches High.
