How did Wace’s Roman de Brut help spread Arthurian legends?

Wace’s Roman de Brut (1155) played a pivotal role in the dissemination and evolution of Arthurian legends by transforming Geoffrey of Monmouth’s Historia regum Britanniae into a more accessible, romanticized verse narrative.12

Written in octosyllabic verse, Wace’s work served as a bridge between Latin chronicles and the later development of courtly romance. His primary contribution to the spread of these legends was the inclusion of several fanciful additions that captured the medieval imagination, most notably the introduction of the story of King Arthur’s Round Table.13

By adapting the material into the vernacular, Wace made the Arthurian cycle more popular and stylistically influential for subsequent writers. His artistry in the Brut not only helped popularize the legends but also provided a foundational source for later works, including the Middle English Brut by Layamon, which was the first work in English to treat the "matter of Britain".12
