Note 366 — Chapter VII · THE CASTLES OF THE NORMANS IN ENGLAND
Reading edition
Dugdale’s Baronage, i., p. 99. Dugdale’s authority appears to have been the “Historia Laceiorum,” a very untrustworthy document, but which may have preserved a genuine tradition in this instance. The loopholes in the basement of the keep, with the large recesses, appear to have been intended for crossbows, and the crossbow was not reintroduced into England till the reign of Richard I.
