Adjective
Galfridian (comparative more Galfridian, superlative most Galfridian)
Of or relating to Geoffrey of Monmouth (c.1100–c.1155), cleric and one of the major figures in the development of British historiography and the popularity of tales of King Arthur.
There have been few attempts to define the nature and character of Arthur in the pre- Galfridian tradition as a whole, rather than in a single text or text/story-type. Source: Internet
