The heart of Ceraunus was now filled with exultation and pride. All his schemes had proved successful, and he found himself, at last, in secure possession, as he thought, of a powerful and wealthy kingdom. He wrote home to his brother in Egypt, Ptolemy Philadelphus--by whom, as the reader will recollect, he had been supplanted there, in consequence of his father's preference for the children of Berenice--saying that he now acquiesced in that disposition of the kingdom of Egypt, since he had acquired for himself a better kingdom in Macedon. He proceeded to complete the organization of his government. He recruited his armies; he fortified his towns; and began to consider himself as firmly established on his throne. All his dreams, however, of security and peace, were soon brought to a very sudden termination.
There was a race of half-civilized people on the banks of the Danube called Gauls. Some tribes of this nation afterward settled in what is now France, and gave their name to that country. At the period, however, of the events which we are here relating, the chief seat of their dominion was a region on the banks of the Danube, north of Macedon and Thrace. Here they had been for some time concentrating their forces and gradually increasing in power, although their movements had been very little regarded by Ceraunus. Now, however, a deputation suddenly appeared at Ceraunus's capital, to say that they were prepared for an invasion of his dominions, and asking him how much money he would give for peace. Ceraunus, in the pride of his newly-established power, treated this proposal with derision. He directed the embassadors to go back and say that, far from wishing to purchase peace, he would not _allow_ peace to them, unless they immediately sent him all their principal generals, as hostages for their good behavior. Of course, after such an interchange of messages as this, both parties immediately prepared for war.
Ceraunus assembled all the forces that he could command, marched northward to meet his enemy, and a great battle was fought between the two armies. Ceraunus commanded in person in this conflict. He rode into the field at the head of his troops, mounted on an elephant. In the course of the action he was wounded, and the elephant on which he rode becoming infuriated at the same time, perhaps from being wounded himself too, threw his rider to the ground. The Gauls who were fighting around him immediately seized him. Without any hesitation or delay they cut off his head, and, raising it on the point of a pike, they bore it about the field in triumph. This spectacle so appalled and intimidated the army of the Macedonians, that the ranks were soon broken, and the troops, giving way, fled in all directions, and the Gauls found themselves masters of the field.
