The Balista
as the trough is drawn back by the windlass to make ready the engine,
is also shown.
1 The balls used by the ancients in their catapults and balistas were
often formed of heavy pebbles inclosed in baked clay, the reason being
that the balls made this way shattered on falling an hence could not be
shot back by the engines of the enemy. The balistas for throwing arrows,
and those employed for casting stones, were fitted with axles and wheels
when constructed for use in field warfare. (Pages 260, 273, 300, The Crossbow.)
The trough has a keel to it, and slides to and fro along the stock in
the same manner as in the arrow throwing balista. (Fig. 7, p. 19.)
Compare with figs. 7, 8, pp. 19, 21 for further explanation of details.
For a detailed account of the history and effects in warfare of catapults,
balistas, and other ancient projectile engines, refer to Chapters LII,
LIII, LIV, and LVIII of The Crossbow.
