Wording
To Master Robert de Pykerynge, dean of St. Peter's York. Order to permit the constables of the wards of the city to levy without hindrance the tallage imposed by the mayor, bailiffs, and citizens by unanimous consent upon their rents and chattels in the city in order to repair and strengthen the walls and ditches and other defences (fortaliciis) of the city, as the king is given to understand that the dean hinders the constables by ecclesiastical censures from levying the tallage from certain tenements that are held of the king in chief.
Granted by Edward II. (Regnal year 14). Granted at Marlborough.

Comments
At first, perhaps, repairs were carried out with the funds raised from murage tolls but at least by 1321 the city was levying a tallage for the purpose; in that year the Crown confirmed the city's right to levy such a tallage on tenements held of the king in chief. (VCH)
