Robert de Boron

Robert de Boron was a French poet active around the late 12th and early 13th centuries, notable as the reputed author of the poems Joseph d'Arimathie and Merlin. Although little is known of Robert apart from the poems he allegedly wrote, these works and subsequent prose redactions of them had a strong influence on later incarnations of the Arthurian legend and its prose cycles, in particular through their Christianisation and redefinition of the previously ambiguous Grail motif and the character of Merlin, as well as vastly increasing the prominence of the latter.
