Completed in 1136, The History of the Kings of Britain traces the story of the realm from its supposed foundation by Brutus to the coming of the Saxons some two thousand years later. Vividly portraying legendary and semi-legendary figures such as Lear, Cymbeline, Merlin the magician and the most famous of all British heroes, King Arthur, it is as much myth as it is history and its veracity was questioned by other medieval writers. But Geoffrey of Monmouth's powerful evocation of illustrious men and deeds captured the imagination of subsequent generations, and his influence can be traced through the works of Malory, Shakespeare, Dryden and Tennyson.
Very little is known of Geoffrey of Monmouth. He seems to have lived for a time in Oxford and in 1151 he became Bishop Elect of St Asaph, North Wales. He was ordained at Westminster in 1152. According to the Welsh Chronicles he died in 1155. Lewis Thorpe was Professor of French at Nottingham University from 1958 to 1977. He has published many books and articles on Arthur, both on the French and English traditions. He died in 1977.
