C. Julius Caesar, Gallic War

Having provided corn and selected his cavalry, he began to direct his march toward those parts in which he heard the Germans were. When he was distant from them only a few days' march, embassadors came to him from their state, whose speech was as follows: "That the Germans neither make war upon the Roman people first, nor do they decline, if they are provoked, to engage with them in arms; for that this was the custom of the Germans handed down to them from their forefathers, -to resist whatsoever people make war upon them and not to avert it by entreaty; this, however, they confessed,-that they had come hither reluctantly, having been expelled from their country. If the Romans were disposed to accept their friendship, they might be serviceable allies to them; and let them either assign them lands, or permit them to retain those which they had acquired by their arms; that they are inferior to the Suevi alone, to whom not even the immortal gods can show themselves equal; that there was none at all besides on earth whom they could not conquer."
