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.
Sermo Lupi ad Anglos The Sermo Lupi ad Anglos ('The Sermon of the Wolf to the English') is the title given to a homily composed in England between 1010-1016 by Wulfstan II, Archbishop of York (died 1023), who commonly styled himself "Lupus", or 'wolf' after the first element in his name ["wulf-stan" = 'wolf-stone']. Though the title is Latin, the work itself is written in Old English. The "Sermo Lupi" is Wulfstan's most well-known work. In it, he blames a lack of moral discipline amongst his fellow English as the source of God's anger against the English, which has taken the shape of thirty years of Viking raids against England. Wulfstan exhorts the English to behave in a manner more pleasing to God, and specifically to live according to the laws of the Church and of the king. The "Sermo Lupi" is noted for its rhetorical achievements, and is considered to represent the height of Wulfstan's skill as a homilist and rhetor. The text of the "Sermo Lupi" has been critically edited many times, most recently by Dorothy Bethurum. The work contains one of several mentions of Old English "wælcyrian", a term cognate to the Old Norse "valkyrjur"—valkyries.
