Nennius – History of the Britons (Historia Brittonum)
Historia Brittonum, or a History of the Britons, was purportedly written in the 8th Century by a Welsh monk called Nennius. It is one of the earliest histories of the British Isles. Nennius’ work influenced later, better known, histories and remained influential for centuries. Many myths and legends about the origins of Britain first appeared in Historia Brittonum. It claimed that Britain was settled by Trojan. 12 battles are cited as having Arthur as a military commander, being the first text to do so. The actual authorship and precise meaning of Historia Brittonum have been subject of much scholarly debate over the last 150 years.
