Arbalest

Not to be confused with Arbalist (crossbowman).

The arbalest (also arblast), 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.

Nomenclature

The term "arbalest" is sometimes used interchangeably with "crossbow". Arbalest is a Medieval French word originating from the Roman name arcuballista (from arcus 'bow' + ballista 'missile-throwing engine'), which was then used for crossbows, although originally used for types of artillery. Modern French uses the word arbalète, which is linguistically one step further from the stem (disappearance of the s phoneme in the last syllable, before the t).

The word applies to both crossbow and arbalest (the latter may be referred to as a heavy crossbow, but an actual heavy crossbow may not be the same as an arbalest). In some cases, the word has been used to refer to arbalists, the people who actually used the weapon.
