It seems probable that the jealousy with which Maraboduus, the king of the Suevi and Marcomanni, regarded Arminius, and which ultimately broke out into open hostilities between those German tribes and the Cherusci, prevented Arminius from leading the confederate Germans to attack Italy after his first victory. Perhaps he may have had the rare moderation of being content with the liberation of his country, without seeking to retaliate on her former oppressors. When Tiberius marched into Germany in the year 10, Arminius was too cautious to attack him on ground favourable to the legions, and Tiberius was too skilful, to entangle his troops in difficult parts of the country. His march and counter-march were as unresisted as they were unproductive. A few years later, when a dangerous revolt of the Roman legions near the frontier caused their generals to find them active employment by leading them into the interior of Germany, we find Arminius again energetic in his country's defence. The old quarrel between him and his father-in-law, Segestes, had broken out afresh. Segestes now called in the aid of the Roman general, Germanicus, to whom he surrendered himself; and by his contrivance his daughter Thusnelda, the wife of Arminius, also came into the hands of the Romans, being far advanced in pregnancy. She showed, as Tacitus relates, [Ann. i. 57.] more of the spirit of her husband than of her father, a spirit that could not be subdued into tears or supplications. She was sent to Ravenna, and there gave birth to a son, whose life we find, from an allusion in Tacitus, to have been eventful and unhappy; but the part of the great historian's work which narrated his fate has perished, and we only know from another quarter that the son of Arminius was, at the age of four years, led captive in a triumphal pageant along the streets of Rome.
