Resumen de Fabricae armorum, Ars barbaricaria et ateliers monétaires en contexte urbain. Entre adaptations techniques et contrôle étatique (ive-viie s.)
Late Roman and early Byzantine helmets shape is the result of a long technical research began as early as classical times in the Middle East. They have a common characteristic that distinguishes them from imperial Roman helmet. The manufacture of the composite bowl is the work of both imperial workshops and mints drawn together into walled cities, between the end of the 3rd and the beginning of the 7th centuries. Barbarian migrations and the fall of the pars occidentalis have not reversed this system. On the contrary, there appeared to be a constant search of technical innovation within imperial workshops. These looked for ease of the damaged parts service or replacement. Eastern workshops have their headquarters located in major fortified cities, with mint, such as Constantinopolis, Nicomedia, Cyzicus, Thessaloniki and Antioch, that last far beyond the 5th century. They were the focal area of an intellectual profusion where war industry and science have interacted. It cannot therefore be concluded that Empire ability to supply and equip its troops has been seriously disrupted, during this period, by the loss of numerous territories with the severance of some supply chains.
