The course of Roman history, hitherto disturbed only by petty border wars, now suffers a great convulsion. Over her neighbours on the east and north the republic was in the ascendant; on the west the frail oligarchies of Etruria had sunk before Camillus and his hardy soldiers; when, by an untoward union of events, Rome saw her best general banished, and heard of the barbarian host which was wasting the fair land of Italy. The Gauls burst upon Latium and the adjoining lands with the suddenness of a thunderstorm. It swept over the face of Italy, crushing and destroying. The Etruscans were weakened by it; and if Rome herself was laid prostrate, the Latins also suffered greatly, the Volscians trembled, and the Æquians were irrecoverably weakened. The Gauls were a tribe of that large race of mankind who are known under the name of Celts, and who at the time in question peopled nearly the whole of western Europe, from the heart of Germany to the ocean. The northern and central parts of the continents were already in the hands of various nations, called by the common name of Germans or Teutons, to whom belonged the Goths, Saxons, Danes, Normans, Lombards, Franks, and Alamanni, while the Celts possessed France, a great part of Germany, most of Spain and Portugal, together with the British Isles. Of these Celts there were two great divisions, commonly called Gael and Cymri, differing in habits and language. The ancient inhabitants of France were Gael, those of Britain and Belgica were Cymri; and the Druidical religion, though sometimes adopted by the Gael, was properly and originally Cymric. Gael are still found in Ireland and in the Highlands of Scotland; Cymri in Wales and Low Brittany; and they have left traces of their name in Cumberland. Before the time we are now speaking of, there had been a great movement in the Celtic nations. Two great swarms went out from Gaul. Of these, one crossed the Alps into Italy; the other, moving eastward, in the course of time penetrated into Greece, and then passed into Asia Minor, where they were known under the name of Galatians.
