Cronicl o Wech Oesoedd
NLW MS 5276D

The massive Welsh history written by Elis Gruffydd in Calais, ca. 1550. Most of the work has not been translated, but it is notable for providing the earliest version of "Ystoria Taliesin" and versions of the story of Maelgwn's wife and the ring (found in one of the saints' lives) and what looks like a retelling of the Vita Merlini.
