Geoffrey of Monmouth’s 'Historia Regum Britanniae' appeared in 1136. In his six-part account the author discusses the ‘history’ of the Britons, from the coming of Brutus to the Saxons’ arrival. He also referrers to the ‘Prophecies of Merlin’ and sheds new light on the ‘history’ of king Arthur. Aaron Thompson’s translated version was the first of its kind in the English language. This 1718 edition includes an extensive preface by Thompson in which he assesses the accuracy of Geoffrey’s accounts.
