Brut Chronicle (also known as Prose Brut) is the name given to a group of chronicles of the history of England which are heavily based on the Historia regum Britanniae written by Geoffrey of Monmouth. The chronicle begins with the legend of Brutus, a prince of Trojan descent (the great-grandson of Aeneas) who arrived in England after being banished from his country. Once arrived in the new land, Brutus defeats some giants who lived there and foundsed the city of London.

There are several versions and translations of this chronicle, which was originally written in Anglo-Norman. The version contained in this manuscript stops at the Fair of Haddington in 1333, during the reign of Edward III. Compare this text with that contained in other manuscripts: British Library, MS Harley 200; Oxford, Bodleian Library, MS Douce 128; Cambridge, Trinity College, MS 723. The text contained in these latter manuscripts is however slighly shorter and presents great variations in spelling.

The poetic prologue which precedes the chronicle is kwnow as Des grantz geanz and it is sometimes transmitted independently in the manuscript tradition (see article cited in bibliography).

Prologue: it begins on f. 47r with the words Si peot homme savoir coment, Quant et de quelle gent, Grantz geantz vindrent, Qe Engleterre primes tiendrent; it ends on f. 52v with the words Rien grevera de savoir les escilles et les escriptures, des ancienes aventures.

Chronicle: begins on f. 53r with the words En la noble citee de grand Troie, il lui avoit un forte chivaler puissant et de grant poer; it ends incompletely on f. 201v with the words des Engleis et occirent qant qils [...] et devant eux et priesterent totes [...] estes et bien dun chose et dautre [...] et trouerent.
