A medieval bestseller that fooled the world for four hundred years
In short: Written around 1136, Geoffrey of Monmouth’s Historia regum Britanniae was long accepted as historical truth. This imaginative chronicle of British kings, from Trojan founders to the Anglo-Saxon era, shaped national identity and literature, despite being dismissed by critics as a complete fabrication. It remains a cornerstone of the Matter of Britain.
Geoffrey of Monmouth, a Welsh cleric, claimed his work was a translation of a very ancient book in the British language provided by Walter, Archdeacon of Oxford. Modern scholars reject this, noting that the text draws from earlier sources like Gildas, Bede, and Nennius, woven together with Geoffrey’s own invention. While once treated as a factual record by chroniclers like Robert of Torigny and Henry of Huntingdon, it is now recognized as a work of fiction.
The narrative spans two millennia, beginning with the Trojan hero Brutus, who allegedly landed at Totnes and established the city that became London. The text chronicles the reigns of legendary figures, including the earliest known account of King Lear and his daughters. It also popularized the legend of King Arthur, detailing his conquests and his eventual departure to the isle of Avalon after the Battle of Camlann.
A significant portion of the work is dedicated to the prophecies of Merlin, which were sometimes circulated independently and used as political tools in later centuries. Although critics like William of Newburgh denounced the book as a collection of impudent falsifications, its influence was immense. It was translated into various languages, including the Welsh Brut y Brenhinedd, and provided foundational material for centuries of British lore and literature.
The manuscript tradition is complex, with two hundred and fifteen medieval copies surviving. While the title Historia regum Britanniae became standard, a 2007 critical edition confirmed that Geoffrey himself titled the work De gestis Britonum. Despite its historical inaccuracies, the text was instrumental in bringing Welsh culture into the broader British consciousness, leaving an indelible mark on the Western literary canon.
