The “Mayor” and “Real” castles of the town of Calatayud in 1371 in the light of two inventories of the Royal Archive

The text shows the study of two interesting inventories mentioning the objects of two castles (“Mayor” and “Real”) of Calatayud (Aragon), carried out in 1371. Firstly, the original text in Catalan of the Archive of the Crown of Aragon has been transcribed. The work is focused on the elements of armour, arms and artillery machines; the nature and function of every object have been researched, comparing, as far as possible, with other contemporary sources; the terminology has also been analysed and some evident Aragonese words have been found.
