Renowned authority M. C. Bishop investigates the origins, development, manufacture, decoration and use of the Roman cavalry helmet. Roman cavalry helmets of the Republican period at first differed little from the infantry helmets and identifying them proves a challenging but not impossible task. In this study, M.C. Bishop reveals how changes to the Roman Army under the Principate at the end of the 1st century BC, not least the incorporation of auxiliary forces, brought changes, with cavalry and infantry helmet types soon diverging. Notably, the Principate saw the introduction of face-mask helmets specifically for use in the hippika gymnasia, a form of combined mounted training and display manoeuvres. As with Roman infantry helmets, contact with Eastern cultures led to completely new types of cavalry helmet being introduced. As this study shows, this simplified helmet manufacture and ultimately led directly to a variety of post-Roman helmet types found, among others, with Saxon and Viking warriors. All of these types are described and illustrated in this ground-breaking work, featuring eight pages of specially commissioned full-colour artwork. This timely and accessible book builds on new finds and the latest research to chart the origins, evolution and legacy of the Roman cavalry helmet.
