A suspicion of another type of abuse of power, more degrading though not necessarily more harmful than the plunder of subjects, had begun to be raised in the minds of the people and the government. It was held that a Roman might be found who would sell the supposed interests of his country to a foreign potentate, or at any rate accept a present which might or might not influence his judgment, A commissioner to Illyria had been suspected of pocketing money offered him by the potentates of that district in 171,[127] and the first hint was given of that shattering of public confidence in the integrity of diplomatists which wrought such havoc in the foreign politics of the period which forms the immediate subject of our work. The system of the Protectorate, which Rome had so widely adopted, with its secret diplomatic dealings and its hidden conferences with kings, offered greater facilities for secret enrichment, and greater security for the enjoyment of the acquired wealth, even than the plunder of a province. The proof of the committal of the act was difficult, in most cases impossible. We must be content to chronicle the suspicion of its growing frequency, and the suspicion is terrible enough. If the custom of wringing wealth from subjects and selling support to potentates continued to prevail, the stage might soon be reached at which it could be said, with that element of exaggeration which lends emphasis to a truth, that a small group of men were drawing revenues from every nation in the world.[128]
