Granted at Westminster. Grant by By K..

Although this document has been considered by some as a licence to crenellate it is rejected as a licence.


Pettifer writes that the Mortimers were granted a licence to crenellate in 1316. This does not seem to be mentioned by any other source. There is a licence, of 1316, for Roger Mortimer to grant the castle of Dynbuad (and numerous other castles and manors in Wales) to John de Hothum and Philip ap Howel (CPR p. 491). Presumably this is what Pettifer is referring to although that is clearly not a licence to crenellate.

Care should also be taken to avoid giving modern meaning to the medieval use of certain stock words and terms. Licentia is best translated as 'freedom to' not 'permission'.)

Significant later sources are;
