They were also superintendents of the observance of religious rites, of the practice of the ritual demanded by the gods. Still subject to those gods, the people would fear the priest not less than the magistrate. Kings, even, were awed by these mouthpieces of the most high. Such was he whom the Aedui chose for their ambassador. Divitiacus went to Rome, and there, in person, pleaded his cause before the senate. His embassy seems to have been of little apparent effect; but, though he lost his suit, he gained a friend--Cicero. In spite of the Druid's failure, Cæsar's legions were, nevertheless, soon on their way to Gaul. The Helvetii, coveting the fertile land that lay beside theirs, decided to attempt its conquest. Cæsar, aided by some Aeduen troops, who now fought for the first time beneath the eagle, met the invaders on the banks of the Saône,[12] and annihilated them in the first great battle of his life. Henceforth, for a time, the two nations are brothers. "Aeduii, fratres nostri, pugnant."[13] Such they remained; until the next nation that threatened them--Ariovistus and his German hordes--had suffered the fate of the Helvetii. It was, however, inevitable that the warlike tribes of Gaul should endeavour, sooner or later, to throw off the yoke of an alien civilization, which, while it brought them material blessings of inestimable value--of which not the least was the introduction of the vine,--was, nevertheless, galling to their spirit of sturdy independence. Soon the Aedui were being stirred to revolt. Foremost among the discontents, was the leader of the Aeduen cavalry, Dumnorix, brother to Divitiacus, though his opposite in character. The trusted ally of Cæsar, and the friend of Cicero, Divitiacus the Druid accepted philosophically the Roman dominion; his brother, turbulent, adventurous, restless--a Prince Rupert of his day--had other dreams for his country. Cæsar was about to embark on his second expedition to Britain, when the news came that Dumnorix, who was under orders to accompany him, had withdrawn, followed by the Aeduen cavalry. Cæsar, delaying his embarkation, sent his own cavalry in pursuit, with orders to kill or capture the rebel, if he refused to submit. Soon overtaken, Dumnorix defended himself valiantly, and fell, sword in hand, with the cry on his lips: "I die a free citizen of a free country."[14] One is tempted to wish that the people of Autun had raised in the "Place des Marbres," beside that of his more philosophic brother, a statue to this gallant leader of a forlorn hope.
