Now, since—as the lofty bard of Mantua said of old—a greater work[*](Aen. vii. 44 f, maior rerum mihi nascitur ordo, Maius opus moveo.) undertake, a greater train of events ariseth before me, I think now a suitable time to describe the regions and situation of the Gauls, for fear that amid fiery encounters and shifting fortunes of battle I may treat of matters unknown to some and seem to follow the example of slovenly sailors, who are forced amid surges and storms to mend their worn sails and rigging, which might have been put in order with less danger.
The ancient writers, in doubt as to the earliest origin of the Gauls, have left an incomplete account of the matter, but later Timagenes,[*](Timagenes of Alexandria, who, according to Suidas, was brought to Rome as a prisoner of war by Pompey. He wrote a History of Alexander and a History of the Gauls. Cf. Hor., Epist. i. 19, 15; Quint., i. 10, 10; x. i. 75.) a true Greek in accuracy as well as language, collected out of various books these facts that had been long forgotten; which, following his authority, and avoiding any obscurity, I shall state clearly and plainly.
