-The Historia regum Britanniæ

A Welsh cleric who lived in the early 12th century, Geoffrey is remembered through his Historia regum Britanniæ, in which he tells the history of England’s pre-Saxon kings from the mythical founder, the Trojan Brutus, through the Welsh king Cadwallader, who is said to have died in 689. The reign and exploits of King Arthur form a central part of Geoffrey’s Historia, including his victory over the Saxons at the City of Legions, which is imagined as a rich English city home to significant churches and a college. Geoffrey also describes Lin Ligua, a deep tidal pool off the coast of south Wales that regularly shoots up a large spout of water. This work is no longer considered to be historically accurate, but it did help to solidify the popular legend of King Arthur.
