Arthurian legends (tales related to the character of King Arthur) derive from many sources, such as Preiddeu Annwfn, composed around 900, and Erec and Enide from around 1170. One of the most significant sources, Geoffrey of Monmouth's History of the Kings of Britain, was written in the 1130s; some material from it was later adapted by the Norman poet Wace into the Roman de Brut in 1155. But while the Roman de Brut includes references to the famous Round Table at which Arthur's knights assembled, nothing written before 1155 does, which suggests that

Roman de Brut is more historically accurate than History, because Erec and Enide had not been written when Geoffrey of Monmouth was writing his work.

Geoffrey of Monmouth was unaware of stories of the Round Table when composing his History, though historians know that works containing such stories were available to him.

Geoffrey of Monmouth's accounts of Arthurian legends in his History are more similar overall in content to the accounts in Erec and Enide than they are to the accounts in Roman de Brut.

any Arthurian legend that mentions the Round Table likely has a lineage that connects it to Roman de Brut.
