It was while he was in prison under sentence of death that Boethius wrote his impassioned The Consolation of Philosophy. Impending extinction concentrated his mind wonderfully: this masterpiece became one of the most widely read books of medieval times. King Alfred the Great, Chaucer and Queen Elizabeth I were among those who made English translations of it. It might never have been written had Boethius lived to a ripe, uneventful and scholarly old age instead of getting caught up in politics.
