What did Pseudo-Ingulf write that is an important primary source for English medieval history, particularly the late 15th century?
Croyland Chronicle The Croyland or Crowland Chronicle is an important primary source for English medieval history, particularly the late 15th century. It is named for its place of origin, the Benedictine Abbey of Croyland or Crowland, in Lincolnshire, England. It was formerly also known as the Chronicle of Ingulf or Ingulphus after its supposed original compiler, the 11th-century abbot Ingulf. As that section of the text is now known to have been a later forgery, he is instead known as Pseudo-Ingulf.
Sir Isumbras Sir Isumbras is a medieval metrical romance written in Middle English and found in no fewer than nine manuscripts dating to the fifteenth century. This popular romance must have been circulating in England before 1320, because William of Nassington, in his work "Speculum Vitae", which dates from this time, mentions feats of arms and other 'vanities', such as those found in stories of "Sir Guy of Warwick", "Bevis of Hampton", "Octavian" and "Sir Isumbras". Unlike the other three stories, the Middle English "Sir Isumbras" is not a translation of an Old French original.
