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.
L'Histoire de Guillaume le Marechal L'Histoire de Guillaume le Marechal (English:"The History of William Marshal") is the verse biography of William Marshal, 1st Earl of Pembroke (1146 or 1147 – 14 May 1219), written shortly after his death at the request of his son, William Marshal, 2nd Earl of Pembroke. The biography is composed of 19,214 lines, in rhyming octosyllabic couplets, and was written in the Anglo-Norman language. It is the major extant text documenting Marshal's life. It was written based on the surviving account of his squire John D'Erlay. It can be used to provide insight into the two English kings, Richard I and his successor John, both of whom William served. The single surviving manuscript of the work, dating perhaps from the second quarter of the thirteenth century, was once in the collection of Sir Thomas Phillipps, and is now housed at the Pierpont Morgan Library in New York City, under the catalog number M888.
