Turban Helmet, 15th century - Public domain photo of museum object

In Ottoman Turkey, some mystical dervish groups would wear turbans folded several times to reflect some important mystical number. The fluted design of the turban helmet might replicate this practice; this indicates that the turban helmet is also worn as a kind of religious insignia. The religious nature of the turban helmet was underlined by the presence of Arabic inscriptions taken from the Quran. These Quranic inscriptions supposedly provided God's protective power to the wearer. Most inscriptions on turban helmets, instead glorify the name of the ruler to whom the warrior was loyal. Other inscriptions were written as advice on how to gain virtue. The heavy religious symbolism in the turban helmet indicates that the warriors wearing the helmet were involved in a kind of Holy War. Turban helmets were designed and worn together with a mail and plate armor shirt or jacket in the heavy cavalries. Several armors displayed in museum shows that both artifacts have matching decoration. After the development of firearms, turban helmets lost their military value, becoming ceremonial objects that were traded and displayed to show wealth. Some turban helmets have inscriptions inlaid with precious metals like gold and silver, with decorations of arabesque motifs around the edges.
