Arbalest

Form of medieval crossbow

The arbalest, a variation of the crossbow, came into use in Europe around the 12th century. The arbalest was a large weapon with a steel prod, or bow assembly. Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force. The greater draw weight was offset by a shorter draw length, which limited the total potential energy that could be transferred into the crossbow bolt. A skilled arbalestier (arbalester) could loose two bolts per minute.
