Crist (Old English for Christ), is the title given to a triad of Old English religious poems in the Exeter Book comprising a total of 1664 lines and dealing with Christ's Advent, Ascension and Last Judgment. It was originally thought to be one piece completed by a single author, but the poem is now broken up into three parts:
Christ I (also Christ A or Advent Lyrics), a collection of twelve anonymous Old English poems dealing with Christ's Advent.
Christ II (also Christ B), a poem written by the Anglo-Saxon poet Cynewulf on Christ's Ascension.
Christ III (also Christ C), an anonymous poem on the Last Judgment.
It and Beowulf are the primary examples of Anglo-Saxon literature.
