Early forms Nasal helmet

helmet of saint wenceslaus, prague the nasal helmet characterised possession of nose-guard, or nasal , composed of single strip of metal extended down skull or browband on nose provide facial protection. helmet appeared throughout western europe late in 9th century, , became predominant form of head protection, replacing previous types of helmet design based on late roman types such ridge helmet , helmets of spangenhelm construction. nasal helmets universally conical in shape. skull raised single sheet of iron or of composite, segmented (spangenhelm) construction. spangenhelm variety was, in general, earlier method of construction. single-piece skulls, being technically more difficult produce, became more common increase in metallurgical skill on time. though nasals had been used on earlier helmets, , on contemporary helmets found in byzantium, slavic eastern europe , middle east, characteristic of nasal helmet in general larger , integrated either skull or browband of helmet. nasal...
