A
cross-bow is a small, horizontal bow. Cross-bows were made of wood
and were used by the Normans at the
Battle of
Hastings. The bolt was laid in a groove along the top of
the wooden tiller. The bolt was aimed by holding the end of the tiller
to the cheek. The bolt was released by pressing a trigger at the rear
of the tiller.
