A mid 15th century manuscript in English prose entitled Here begynneth a booke which is called Brute, the Cronycles of Englonde. There is an introductory paragraph (as in Harley MSS 1337, 2182 and 6251 and Stowe MS 71) beginning 'This booke treteth and telleth of the kynges and principal lordes that euer were in this londe ...' followed by a long rubric (as in Harleian MS 2182), mainly defaced, beginning 'The prolog of this booke declareth hou this [londe] was callyd Albyon ...'. The text begins on p. 2 and, like the majority of the manuscripts of the English Brute (see F. W. D. Brie, Geschichte und Quellen der mittelenglischen Prosachronik The Brute of England, 1905, p. 62), this manuscript ends with the capture of Rouen by Henry V in 1419. Illuminated initial and border on p. 1; chapter-initials in blue, with red flourishes; headings in red.

A manuscript written in two hands containing Historia Brittonum, et Cronice de Gestis ac Nominibus Regum Anglie. Beginning at p. 132 is a brief continuation of the Chronicles down to Henry VI in a later hand.
