Piers Langtoft (died ~1307) was a
chronicler who originated from
Langtoft[?] in
Yorkshire. He was an
Augustinian monk at
Bridlington Priory[?], and wrote his own history of
England in verse. The period covered is up to the death of King
Edward I of England. It is thanks to Langtoft that we know the fate of Gwenllian, daughter of
Llywelyn the Last of Wales.
