Book excerpt: Medieval literature is to a large degree shaped by orality, not only with regard to performance, but also to transmission and composition. Although problems of orality have been much discussed by medievalists, there is to date no comprehensive handbook on this topic. ‘Medieval Oral Literature’, a volume in the ‘De Gruyter Lexikon’ series, was written by an international team of twenty-five scholars and offers a thorough discussion of theoretical approaches as well as detailed presentations of individual traditions and genres. In addition to chapters on the oral-formulaic theory, on the interplay of orality and writing in the Early Middle Ages, on performance and performers, on oral poetics and on ritual aspects of orality, there are chapters on the Older Germanic, Romance, Middle High German, Middle English, Celtic, Greek-Byzantine, Russian, Hebrew, Arabic, Persian and Turkish traditions of oral literature. There is a special focus on epic and lyric, genres that are also discussed in separate chapters, with additional chapters on the ballad and on drama.
