These Gauls had left their country with Brennus, and having survived the battle at Delphi and made their way to the Hellespont, instead of crossing to Asia, were captivated by the beauty of the district round Byzantium, and settled there. Then, having conquered the Thracians and erected Tyle into a capital, they placed the Byzantines in extreme danger. In their earlier attacks, made under the command of Comontorius their first king, the Byzantines always bought them off by presents amounting to three, or five, or sometimes even ten thousand gold pieces, on condition of their not devastating their territory: and at last were compelled to agree to pay them a yearly tribute of eighty talents, until the time of Cavarus, in whose reign their kingdom came to an end; and their whole tribe, being in their turn conquered by the Thracians, were entirely annihilated. It was in these times, then, that being hard pressed by the payment of these exactions, the Byzantines first sent embassies to the Greek states with a prayer for aid and support in their dangerous situation: but being disregarded by the greater number, they, under pressure of necessity, attempted to levy dues upon ships sailing into the Pontus.
