Los castillos Mayor y Real de la ciudad de Calatayud en el año 1371 a la luz de dos inventarios del Archivo Real

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. This work has allowed to know the different elements existing in the castles, establishing their specificity, state and lacks, sometimes not easily explicable, as in the case of the crossbows. The meticulous description of the artillery machines is absolutely exceptional.
