11th-12th century AD. A Norman or Cuman four-plate iron helmet constructed from curved triangular sections converging at the apex; the bowl contoured so that the front and back plates overlap the side-plates by 1-2cm, with iron rivets passing through this overlap to secure them in position; the rivets worked flat into the surface of the helmet, almost invisible from the outside but detectable on the inner surface; the plate-junction at the apex supplied with a small hole, allowing a plume or horsehair streamer to be inserted through a ring; mounted on a custom-made stand.

Property of an East Sussex, UK, gentleman; formerly from an important family collection of a UK gentleman, acquired in the late 1990s; accompanied by an archaeological report by military specialist Dr Raffaele D'Amato; this lot has been checked against the Interpol Database of stolen works of art and is accompanied by AIAD certificate number no.10411-169109. Helmets of this general profile and form are a long-lived military fashion in the Black Sea region, as evidenced by elements of a 7th-8th century Khazar saddle from the Shilovskiy grave field (Samara region"). A similar helmet is housed in the St. Petersburg Museum (inventory reference PA72), for which D’Amato (2015, pp. 65ff.) proposed an Eastern-Roman origin, based on the interchange of Roman and Khazar military technology. Based on a similar 7th century helmet found with a coin of Heraclius, D’Amato proposed that these helmets were a product of the introduction of Steppe technology in Byzantium. This form of helmet is certainly evident in the iconography of 9th-12th century Eastern-Roman helmets.
