time the Romans were pressing on the Etruscans from below, and Roman and Celt were acting in definite concert and alliance. But the Romans, despising perhaps the Northern barbarian warriors, had the rashness to play them false at the siege of Clusium, 391 B.C., a place which the Romans regarded as one of the bulwarks of Latium against the North. The Celts recognised Romans who had come to them in the sacred character of ambassadors fighting in the ranks of the enemy. The events which followed are, as they have come down to us, much mingled with legend, but there are certain touches of dramatic vividness in which the true character of the Celts appears distinctly recognisable. They applied, we are told, to Rome for satisfaction for the treachery of the envoys, who were three sons of Fabius Ambustus, the chief pontiff. The Romans refused to listen to the claim, and elected the Fabii military tribunes for the ensuing year. Then the Celts abandoned the siege of Clusium and marched straight on Rome. The army showed perfect discipline. There was no indiscriminate plundering and devastation, no city or fortress was assailed. “We are bound for Rome” was their cry to the guards upon the walls of the provincial towns, who watched the host in wonder and fear as it rolled steadily to the south. At last they reached the river Allia, a few miles from Rome, where the whole available force of the city was ranged to meet them. The battle took place on July 18, 390, that ill-omened dies Alliensis which long perpetuated in the Roman calendar the memory of the deepest shame the republic had ever known. The Celts turned the flank of the Roman army, and annihilated it in one tremendous charge. Three days later they were in Rome, and for nearly a year they remained masters of the city, or of its ruins, till a great fine had been exacted and full vengeance taken for the perfidy at Clusium. For nearly a century after the treaty thus concluded there was peace between the Celts and the Romans, and the breaking of that peace when certain Celtic tribes allied themselves with their old enemy, the Etruscans, in the third Samnite war was coincident with the breaking up of the Celtic Empire.10
Two questions must now be considered before we can leave the historical part of this Introduction. First of all, what are the evidences for the widespread diffusion of Celtic power in Mid-Europe during this period? Secondly, where were the Germanic peoples, and what was their position in regard to the Celts?
Celtic Place-names in Europe
To answer these questions fully would take us (for the purposes of this volume) too deeply into philological discussions, which only the Celtic scholar can fully appreciate. The evidence will be found fully set forth in de Jubainville's work, already frequently referred to. The study of European place-names forms the basis of the argument. Take the Celtic name Noviomagus composed of two Celtic words, the adjective meaning new, and magos (Irish magh) a field or plain.11 There were nine places of this name known in antiquity. Six were in France, among them the places now called Noyon, in Oise, Nijon, in Vosges, Nyons, in Drôme. Three outside of France were Nimègue, in Belgium, Neumagen, in the Rhineland, and one at Speyer, in the Palatinate.
The word dunum, so often traceable in Gaelic place-names in the present day (Dundalk, Dunrobin, &c.), and meaning fortress or castle, is another typically Celtic element in European place-names. It occurred very frequently in France—e.g., Lug-dunum (Lyons), Viro-dunum (Verdun). It is also found in Switzerland—e.g., Minno-dunum (Moudon), Eburo-dunum (Yverdon)—and in the Netherlands, where the famous city of Leyden goes back to a Celtic Lug-dunum. In Great Britain the Celtic term was often changed by simple translation into castra; thus Camulo-dunum became Colchester, Brano-dunum Brancaster. In Spain and Portugal eight names terminating in dunum are mentioned by classical writers. In Germany the modern names Kempton, Karnberg, Liegnitz, go back respectively to the Celtic forms Cambo-dunum, Carro-aunum, Lugi-dunum, and we find a Singi-dunum, now Belgrade, in Servia, a Novi-dunum, now Isaktscha, in Roumania, a Carro-dunum in South Russia, near the Dniester, and another in Croatia, now Pitsmeza. Sego-dunum, now Rodez, in France, turns up also in Bavaria (Wurzburg), and in England (Sege-dunum, now Wallsend, in Northumberland), and the first term, sego, is traceable in Segorbe (Sego-briga) in Spain. Briga is a Celtic word, the origin of the German burg, and equivalent in meaning to dunum.
One more example: the word magos, a plain, which is very frequent as an element of Irish place-names, is found abundantly in France, and outside of France, in countries no longer Celtic, it appears in Switzerland (Uro-magus now Promasens), in the Rhineland (Broco-magus, Brumath), in the Netherlands, as already noted (Nimègue), in Lombardy several times, and in Austria.
The examples given are by no means exhaustive, but they serve to indicate the wide diffusion of the Celts in Europe and their identity of language over their vast territory.12
Early Celtic Art
The relics of ancient Celtic art-work tell the same story. In the year 1846 a great pre-Roman necropolis was discovered at Hallstatt, near Salzburg, in Austria. It contains relics believed by Dr. Arthur Evans to date from about 750 to 400 B.C. These relics betoken in some cases a high standard of civilisation and considerable commerce. Amber from the Baltic is there, Phoenician glass, and gold-leaf of Oriental workmanship. Iron swords are found whose hilts and sheaths are richly decorated with gold, ivory, and amber.
The Celtic culture illustrated by the remains at Hallstatt developed later into what is called the La Tène culture. La Tène was a settlement at the north-eastern end of the Lake of Neuchâtel, and many objects of great interest have been found there since the site was first explored in 1858. These antiquities represent, according to Dr. Evans, the culminating period of Gaulish civilisation, and date from round about the third century B.C. The type of art here found must be judged in the light of an observation recently made by Mr. Romilly Allen in his “Celtic Art” (p. 13):
“The great difficulty in understanding the evolution of Celtic art lies in the fact that although the Celts never seem to have invented any new ideas, they possessed an extraordinary aptitude for picking up ideas from the different peoples with whom war or commerce brought them into contact. And once the Celt had borrowed an idea from his neighbours he was able to give it such a strong Celtic tinge that it soon became something so different from what it was originally as to be almost unrecognisable.”
Now what the Celt borrowed in the art-culture which on the Continent culminated in the La Tène relics were certain originally naturalistic motives for Greek ornaments, notably the palmette and the meander motives. But it was characteristic of the Celt that he avoided in his art all imitation of, or even approximation to, the natural forms of the plant and animal world. He reduced everything to pure decoration. What he enjoyed in decoration was the alternation of long sweeping curves and undulations with the concentrated energy of close-set spirals or bosses, and with these simple elements and with the suggestion of a few motives derived from Greek art he elaborated a most beautiful, subtle, and varied system of decoration, applied to weapons, ornaments, and to toilet and household appliances of all kinds, in gold, bronze, wood, and stone, and possibly, if we had the means of judging, to textile fabrics also. One beautiful feature in the decoration of metal-work seems to have entirely originated in Celtica. Enamelling was unknown to the classical nations till they learned from the Celts. So late as the third century A.D. it was still strange to the classical world, as we learn from the reference of Philostratus:
“They say that the barbarians who live in the ocean (Britons) pour these colours upon heated brass, and that they adhere, become hard as stone, and preserve the designs that are made upon them.”
Dr. J. Anderson writes in the “Proceedings of the Society of Antiquaries of Scotland”:
“The Gauls as well as the Britons—of the same Celtic stock—practised enamel-working before the Roman conquest. The enamel workshops of Bibracte, with their furnaces, crucibles, moulds, polishing-stones, and with the crude enamels in their various stages of preparation, have been recently
