Cædmon's Hymn in the context of "Old English poetry"

Old English literature refers to poetry (alliterative verse) and prose written in Old English in early medieval England, from the 7th century to the decades after the Norman Conquest of 1066, a period often termed Anglo-Saxon England. The 7th-century work Cædmon's Hymn is often considered as the oldest surviving poem in English, as it appears in an 8th-century copy of Bede's text, the Ecclesiastical History of the English People. Poetry written in the mid-12th century represents some of the latest post-Norman examples of Old English. Adherence to the grammatical rules of Old English is largely inconsistent in 12th-century work, and by the 13th century the grammar and syntax of Old English had almost completely deteriorated, giving way to the much larger Middle English corpus of literature.

In descending order of quantity, Old English literature consists of: sermons and saints' lives; biblical translations; translated Latin works of the early Church Fathers; chronicles and narrative history works; laws, wills and other legal works; practical works on grammar, medicine, and geography; and poetry. In all, there are over 400 surviving manuscripts from the period, of which about 189 are considered major. In addition, some Old English text survives on stone structures and ornate objects.
