Object type: Chichak (turban helmet)
Classification: Arms and Armour - Headgear
Style: Ottoman
Period: Ottoman Empire
Style or period: Ottoman classical age

Historical context: The chichak emerged in the 15th century and matured through the 16th, worn by the sipahi heavy cavalry. Its sliding nasal, ear-flaps and neck-guard balanced protection with vision and mobility for mounted combat; the European "zischagge" is a Germanisation of the Turkish name, and related forms reached Mughal India."""@en ;
