There is very strong evidence that Anglo-Saxon poetry has deep roots in oral tradition, but keeping with the cultural practices seen elsewhere in Anglo-Saxon culture, there was a blending between tradition and new learning. Thus while all Old English poetry has common features, three strands can be identified: religious poetry, which includes poems about specifically Christian topics, such as the cross and the saints; Heroic or epic poetry, such as Beowulf, which is about heroes, warfare, monsters, and the Germanic past; and poetry about "smaller" topics, including introspective poems (the so-called elegies), "wisdom" poems (which communicate both traditional and Christian wisdom), and riddles. For a long time all Anglo-Saxon poetry was divided into three groups: Cædmonian (the biblical paraphrase poems), heroic, and "Cynewulfian," named after Cynewulf, one of the only named poets in Anglo-Saxon. The most famous works from this period include the epic poem Beowulf, which has achieved national epic status in Britain. There are about 30,000 surviving lines of Old English poetry and about ten times that much prose, and the majority of both is religious. The prose was influential and obviously very important to the Anglo-Saxons and more important than the poetry to those who came after the Anglo-Saxons. Homilies are sermons, lessons to be given on moral and doctrinal matters, and the two most prolific and respected writers of Anglo-Saxon prose, Ælfric and Wulfstan, were both homilists. Almost all surviving poetry is found in only one manuscript copy, but there are several versions of some prose works, especially the Anglo-Saxon Chronicle, which was apparently promulgated to monasteries by the royal court. Anglo-Saxon clergy also continued to write in Latin, the language of Bede's works, monastic chronicles, and theological writing, although Bede's biographer records that he was familiar with Old English poetry and gives a five line lyric which he either wrote or liked to quote – the sense is unclear. Symbolism Symbolism was an essential element in Anglo-Saxon culture. Julian D. Richards suggests that in societies with strong oral traditions, material culture is used to store and pass on information and stand instead of literature in those cultures. This symbolism is less logical than literature and more difficult to read. Anglo-Saxons used symbolism to communicate as well as to aid their thinking about the world. Anglo-Saxons used symbols to differentiate between groups and people, status and role in society. The visual riddles and ambiguities of early
