This story deals with the invasion of Britain by the Roman legionaries. Beric, who is a boy-chief of a British tribe, takes a prominent part in the insurrection under Boadicea; and after the defeat of that heroic queen (in A.D. 62) he continues the struggle in the fen-country. Ultimately Beric is defeated and carried captive to Rome, where he is trained in the exercise of arms in a school of gladiators. Such is the skill which he there acquires that he succeeds in saving a Christian maid by slaying a lion in the arena, and is rewarded by being made librarian in the palace, and the personal protector of Nero. Finally he escapes from this irksome service, organizes a band of outlaws in Calabria, defies the power of Rome, and at length returns to Britain, where becomes a wise ruler of his own people.--- 12 illustrations
