Christ I (also known as Christ A or (The) Advent Lyrics), is a fragmentary collection of Old English poems on the coming of the Lord, preserved in the Exeter Book. In its present state, the poem comprises 439 lines in twelve distinct sections. In the assessment of Edward B. Irving Jr, "two masterpieces stand out of the mass of Anglo-Saxon religious poetry: The Dream of the Rood and the sequence of liturgical lyrics in the Exeter Book ... known as Christ I". The topic of the poem is Advent, the time period in the annual liturgical cycle leading up to the anniversary of the coming of Christ, a period of great spiritual and symbolic significance within the Church — for some in early medieval Europe a time of fasting, and the subject of a sermon by Gregory the Great (590-604 CE). The Old English lyrics of Christ I, playing off the Latin antiphons, reflect on this period of symbolic preparation. Manuscript and associated texts Christ I is found on folios 8r-14r of the Exeter Book, a collection of Old English poetry today containing 123 folios. The collection also contains a number of other religious and allegorical poems. Some folios have been lost at the start of the poem, meaning that an indeterminate amount of the original composition is missing. Christ I, concerning the Advent of Jesus, is followed in the Exeter Book by a poem on Jesus's Ascension composed by Cynewulf, generally known in modern scholarship as Christ II, which in turn is followed by Christ III, on the Last Judgment. Together these three poems comprise a total of 1664 lines, and are in turn linked to the poems that follow, Guthlac A and Guthlac B. The sequence of Christ I-III is sometimes known simply as Christ, and has at times been thought to be one poem completed by a single author. Linguistic and stylistic differences indicate, however, that Christ I-III originated as separate compositions (perhaps with Christ II being composed as a bridge between Christ I and Christ III). Nevertheless, Christ I-III stands as an artistically coherent compilation. The text also contains glosses by Laurence Nowell from the sixteenth century or George Hickes from the seventeenth. Origins Because Christ II is signed by Cynewulf, earlier scholarship supposed that Christ I might also be his work; but recent research agrees that the authorship is unknown. Claes Schaar suggested that the
