  rico:scopeAndContent "A cross-cultural study collection tracing the development of the combat helmet across four civilisations and roughly three thousand years - from the royal war-crown of New Kingdom Egypt, through the iron galea of the Roman legions and the flat-topped great helm of the Crusading knight, to the fluted turban helmet of the Ottoman cavalry. Each object is presented as an interactive 3D model for the museum digital-twin exhibition, with the uncompressed source assets preserved alongside the access models."@en ;
