Ferrum inter axiculos duos firmum compaginatur et vastum in modum regulae maioris extentum, cuius ex volumine tereti, quod in medio pars polita componit, quadratus eminet stilus extentius, recto canalis angusti meatu cavatus, et hac multiplici chorda nervorum tortilium illigatus: eique cochleae duae ligneae coniunguntur artissime, quarum prope unam assistit artifex contemplabilis, et subtiliter apponit in temonis cavamine, sagittam ligneam spiculo maiore conglutinatam, hocque facto, hinc inde validi iuvenes versant agiliter rotabilem flexum.
Between two posts along, strong iron bar is fastened, and projects like a great ruler; from its smooth, rounded surface, which in the middle is highly polished, a squared staff extends to a considerable distance, hollowed out along its length with a narrow groove, and bound there with a great number of twisted cords. To this two wooden rollers are very firmly attached, and near one of them stands the gunner who aims the shot. He carefully places in the groove of the projecting iron bar a wooden arrow, tipped with a great iron point. When this is done, strong young men on both sides quickly turn the rollers and the cords.
