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.
