The Quarrel (_carreau_), as its name indicates, was an arrow with a four-sided or pyramidal head. This distinctive form of the arbalest shaft is carefully kept in view in the illumination from Add. MS. 15,268 (our No. 49); where, while the archer plies his barbed arrow, the cross-bowman discharges his angular quarrel. The feathering of the quarrel is seen very clearly in woodcut, No. 50; where the markings shew that _feathers_ are really intended, and not slices of wood, leather, or metal. These last-named materials being found in later monuments, it seems not unlikely that they may have been used thus early; and we have the distinct evidence of cotemporary writers that the _larger_ quarrels discharged from the engines called espringales were "empennés d'airain[385]." The Slings of this period have already been noticed (page 204): the cord-sling is figured in our woodcut, No. 50, the staff-sling in No. 51. The Military Flail appears in the following woodcut from Strutt's _Horda_ vol. i., Plate XXXII. The original miniature is in the MS. of Matthew Paris, at Benet College, Cambridge, which has already furnished us with examples of the Staff-sling and other weapons of this time. The flail-man in our engraving is engaged in the assault of a castle: other assailants in the same vessel are armed with bows and slings. Adelung cites the following passage, in which the flail is mentioned under the name of _flaellum_: "Cum ducentis hominibus in armis, electis et gleatis, et cum flaellis[386]." [Illustration: No. 84.]
