Note 1177 — Chapter XII · STONE CASTLES OF THE NORMAN PERIOD
Reading edition
Payne Gallwey, The Crossbow, p. 3. We find it used by Louis VI. of France, before 1137. Suger’s Gesta Ludovici, 10 (ed. Molinier). Ten balistarii are mentioned in Domesday Book, but they may have been engineers of the great balista, a siege machine. There is no representation of a crossbow in the Bayeux Tapestry. There are entries in the Pipe Rolls of 6, 8, and 9 Henry II. of payments for arbelast, but these also may refer to the great balista.
