Ariovistus, the king of the Germans, who had been voted a friend of the Roman people, came to Cæsar to have a colloquy. After they had separated he wished to have another. Cæsar refused it, but sent some of the leading men of the Gauls to meet him. Ariovistus cast them in chains, wherefore Cæsar threatened him and made war on him, but fear fell upon the army on account of the military reputation of the Germans.Cf. Cæsar's i. 42 seq.
