These Gauls, in a very numerous body, induced either by scarcity of land or hopes of plunder, and thinking that no nation through which they were to pass would be a match for them in arms, made their way under the command of Brennus into Dardania.
There a dissension arose, and about twenty thousand men under the chieftains Leonorius and Lutarius, a secession being made from Brennus, turned their route to Thrace.
Then when, fighting with such as resisted them, and imposing a tribute on such as sued for peace, they had arrived at Byzantium, they held possession for a long time of the cities in that quarter, laying the coast of the Propontis under contribution.
Then a desire of passing over into Asia seized them, hearing in the neighbourhood how great the fertility of that continent was; and, having taken Lysimachia by treachery, and possessed themselves of the whole Chersonesus by force of arms, they went down to the Hellespont.
When they there beheld Asia separated from them by a narrow strait, their wishes to pass into it were much more highly inflamed, and they despatched envoys to Antipater, governor of that coast, to treat of a passage.
And when, business being protracted to a greater length than they expected, a new quarrel broke out between their chieftains, Leonorius, with the greater part of the people, went back to Byzantium, whence they came: Lutarius takes two decked ships and three barks from some Macedonians, sent by Antipater, under the pretext of an embassy, to act as spies. By carrying over in these galleys detachment after detachment, day and night, he transported all his troops within a few days. Not long after, Leonorius, with the assistance of Nicomedes, king of Bithynia, passed over from Byzantium.
The Gauls then re-united their forces, and assisted Nicomedes in a war which he was carrying on against Zybœ — ta, who held possession of a part of Bithynia.
By their assistance chiefly Zybœta was subdued, and the whole of Bithynia reduced under the dominion of Nicomedes.
Then leaving Bithynia, they advanced into Asia; and although, of their twenty thousand men, not more than ten thousand carried arms, yet such a degree of terror did they strike into all the natives, dwelling on this side of Taurus, that those which they-visited, and those which they did not visit, the most re- [p. 1739]
mote as well as the nearest, submitted to their authority.
At length, as there were three tribes of them, the Tolistoboians, the Trocmians, and the Tectosagians, they made a division of Asia into three provinces, according to which it was made tributary to each of their states.
The coast of the Hellespont was assigned to the Trocmians; the Tolistoboians obtained of the allotment Aeolia and Ionia; the Tectosagians received the inland parts of Asia.
They levied tribute throughout every part of Asia on this side Mount Taurus; but chose their own residence on the banks of the river Halys;
and so great was the terror of their name, their numbers, too, increasing by a rapid population, that at last even the kings of Syria did not refuse to pay them tribute.
The first of all the inhabitants of Asia who refused, was Attalus, the father of king Eumenes; and beyond the expectation of all, fortune favoured his bold resolution, and he defeated them in a pitched battle; yet lie did not so effectually break their spirits, as to make them give up their pretensions to empire.
Their power continued the same until the war between Antiochus and the Romans; and, even then, after Antiochus was expelled the country, they still entertained a hope, that, as they lived remote from the sea, the Roman army would not come so far.
