abstract:
A copy (National Library of Wales, Peniarth MS 22) of the Dingestow version of the Brut y Brenhinedd was penned in 1444 by one Dafydd ap Maredudd Glais, who, far from being a professional scribe, led a colourful life including both murder and public service in fifteenth-century Aberystwyth. But he was not, as previously thought, a cleric.
