Langtoft was an Augustinian canon regular at Bridlington Priory who wrote a history of England in Anglo-Norman verse, popularly known as Langtoft's Chronicle.
[1] The first part of Langtoft's chronicle is translated from Wace's Roman de Brut ("Tale of Brutus"), and the second part is drawn from a number of sources, including Henry of Huntingdon's Historia Anglorum ("History of the English").
The third part is widely considered to be original work by Langtoft, and he includes in it details not recorded elsewhere such as the fate of Gwenllian, daughter of Llywelyn ap Gruffudd, Prince of Wales.
On the whole, the chronicle is virulently anti-Scottish and famously contains nine 'songs', in both Anglo-Norman and Middle English, supposedly capturing the taunts between English and Scottish soldiers during the Anglo-Scottish conflicts of the late 13th and early 14th centuries.
Piers Langtoft's Chronicle as translated, illustrated, and improved by Mannyng was later transcribed and published in two volumes by Thomas Hearne in 1725.
