A volume containing a copy, in a hand of the second half of the sixteenth-century, of a verse play in Middle Cornish, based upon the life of St Kea, a Celtic saint venerated in Cornwall and Brittany (see Albert le Grand (de Morlaix), Les vies des saints de la Bretagne Armorique (Quimper, 5th edition, 1901), pp. 561-567) (ff. 1-8 verso).
The second part of the text (ff. 9-20 verso) derives from the accounts given in Geoffrey of Monmouth's Historia Regum Britanniæ (Books ix.15, x.1-13, xi. 1-2) of King Arthur's quarrel with the Roman emperor Lucius Hiberius over the tribute which the Britons were required to pay to Rome, and of the clandestine relationship of Arthur's nephew, Modred, with Queen Guenevere.
