Lucius, Saint of Britain, lived in the 2d century. Bede, in his Ecclesiastical History, says that in 154, under the Roman emperors, Marcus Aurelius and Verus, and during the pontificate of Eleutherus, a British king Lucius wrote to the pope, announcing that he wished to become a Christian. Eleutherus favorably received the communication, and sent priests to instruct the Britons in the Christian faith. A similar account may be found in a number of other traditions.
