Note 1182 — Chapter XII · STONE CASTLES OF THE NORMAN PERIOD
Reading edition
Meyrick in his Ancient Armour quotes a charter of 1239, in which the French king grants a castle to the Count de Montfort on condition “quod non possumus habere in eodem archeriam nec arbalisteriam,” which Meyrick audaciously translates “any perpendicular loophole for archers, nor any cruciform loophole for crossbowmen.” The quotation is unfortunately given by Sir R. Payne Gallwey without the Latin original. It is at any rate probable that the cruciform loophole was for archers; it does not appear till the time of the long-bow, which was improved and developed by Edward I., who made it the most formidable weapon of English warfare.
