 The helmet and visor have marked similarities to a number of other Roman cavalry helmets . The visor is a cavalry sports type C ( H. Russell Robinson classification ) or type V ( Maria <unk> classification ) . Similar examples have been found across the Roman Empire from Britain to Syria . It is of the same type as the Newstead Helmet , found in Scotland in 1905 , and its facial features most closely parallel a helmet that was found at <unk> in Italy and is now in the British Museum . The rendering of the hair is similar to that of a type C helmet found at <unk> in Serbia and dated to the 2nd century AD . The griffin ornament is unique , though it may parallel a lost " sphinx of bronze " that may originally have been attached to the crest of the Ribchester Helmet , discovered in Lancashire in 1796 . The headpiece is nearly unique ; only one other example in the form of a Phrygian cap has been found , in a fragmentary state , at <unk> in Romania , dated to the second half of the 2nd century AD . <unk> on the back of the helmet and on the griffin may have been used to attach colourful streamers or ribbons .
