Cotys in Thrace, who was difficult to be reached and might conveniently be used against Eumenes, obtained pardon and received back his captive son.

Thus the affairs of the north were settled, and Macedonia also was at last released from the yoke of monarchy - in fact Greece was more free than ever; a king no longer existed anywhere.

But the Romans did not confine themselves to cutting the nerves and sinews of Macedonia. The senate resolved at once to render all the Hellenic states, friend and foe, for ever incapable of harm, and to reduce all of them alike to the same humble clientship. The course pursued may itself admit of justification; but the mode in which it was carried out in the case of the more powerful of the Greek client-states was unworthy of a great power, and showed that the epoch of the Fabii and the Scipios was at an end.

The state most affected by this change in the position of parties was the kingdom of the Attalids, which had been created and fostered by Rome to keep Macedonia in check, and which now, after the destruction of Macedonia, was forsooth no longer needed. It was not easy to find a tolerable pretext for depriving the prudent and considerate Eumenes of his privileged position, and allowing him to fall into disfavour. All at once, about the time when the Romans were encamped at Heracleum, strange reports were circulated regarding him - that he was in secret intercourse with Perseus; that his fleet had been suddenly, as it were, wafted away; that 500 talents had been offered for his non-participation in the campaign and 1500 for his mediation to procure peace, and that the agreement had only broken down through the avarice of Perseus. As to the Pergamene fleet, the king, after having paid his respects to the consul, went home with it at the same time that the Roman fleet went into winter quarters. The story about corruption was as certainly a fable as any newspaper canard of the present day; for that the rich, cunning, and consistent Attalid, who had primarily occasioned the breach between Rome and Macedonia by his journey in 582 and had been on that account wellnigh assassinated by the banditti of Perseus, should - at the moment when the real difficulties of a war, of whose final issue, moreover, he could never have had any serious doubt, were overcome - have sold to the instigator of the murder his share in the spoil for a few talents, and should have perilled the work of long years for so pitiful a consideration, may be set down not merely as a fabrication, but as a very silly one. That no proof was found either in the papers of Perseus or elsewhere, is sufficiently certain; for even the Romans did not venture to express those suspicions aloud, But they gained their object. Their wishes appeared in the behaviour of the Roman grandees towards Attalus, the brother of Eumenes, who had commanded the Pergamene auxiliary troops in Greece. Their brave and faithful comrade was received in Rome with open arms and invited to ask not for his brother, but for himself - the senate would be glad to give him a kingdom of his own. Attalus asked nothing but Aenus and Maronea. The senate thought that this was only a preliminary request, and granted it with great politeness. But when he took his departure without having made any further demands, and the senate came to perceive that the reigning family in Pergamus did not live on such terms with each other as were customary in princely houses, Aenus and Maronea were declared free cities. The Pergamenes obtained not a foot's breadth of territory out of the spoil of Macedonia; if after the victory over Antiochus the Romans had still saved forms as respected Philip, they were now disposed to hurt and to humiliate. About this time the senate appears to have declared Pamphylia, for the possession of which Eumenes and Antiochus had hitherto contended, independent. What was of more importance, the Galatians - who had been substantially in the power of Eumenes, ever since he had expelled the king of Pontus by force of arms from Caiatia and had on making peace extorted from him the promise that he would maintain no further communication with the Galatian princes - now, reckoning beyond doubt on the variance that had taken place between Eumenes and the Romans, if not directly instigated by the latter, rose against Eumenes, overran his kingdom, and brought him into great danger. Eumenes besought the mediation of the Romans; the Roman envoy declared his readiness to mediate, but thought it better that Attalus, who commanded the Pergamene army, should not accompany him lest the barbarians might be put into ill humour. Singularly enough, he accomplished nothing; in fact, he told on his return that his mediation had only exasperated the barbarians.

No long time elapsed before the independence of the Galatians was expressly recognized and guaranteed by the senate. Eumenes determined to proceed to Rome in person, and to plead his cause in the senate. But the latter, as if troubled by an evil conscience, suddenly decreed that in future kings should not be allowed to come to Rome; and despatched a quaestor to meet him at Brundisium, to lay before him this decree of the senate, to ask him what he wanted, and to hint to him that they would be glad to see his speedy departure. The king was long silent; at length he said that he desired nothing farther, and re-embarked. He saw how matters stood: the epoch of half-powerful and half-free alliance was at an end; that of impotent subjection began.

Similar treatment befell the Rhodians. They had a singularly privileged position: their relation to Rome assumed the form not of symmachy properly so called, but of friendly equality; it did not prevent them from entering into alliances of any kind, and did not compel them to supply the Romans with a contingent on demand. This very circumstance was presumably the real reason why their good understanding with Rome had already for some time been impaired. The first dissensions with Rome had arisen in consequence of the rising of the Lycians, who were handed over to Rhodes after the defeat of Antiochus, against their oppressors who had (576) cruelly reduced them to slavery as revolted subjects; the Lycians, however, asserted that they were not subjects but allies of the Rhodians, and prevailed with this plea in the Roman senate, which was invited to settle the doubtful meaning of the instrument of peace. But in this result a justifiable sympathy with the victims of grievous oppression had perhaps the chief share; at least nothing further was done on the part of the Romans, who left this as well as other Hellenic quarrels to take their course. When the war with Perseus broke out, the Rhodians, like all other sensible Greeks, viewed it with regret, and blamed Eumenes in particular as the instigator of it, so that his festal embassy was not even permitted to be present at the festival of Helios in Rhodes. But this did not prevent them from adhering to Rome and keeping the Macedonian party, which existed in Rhodes as well as everywhere else, aloof from the helm of affairs. The permission given to them in 585 to export grain from Sicily shows the continuance of the good understanding with Rome. All of a sudden, shortly before the battle of Pydna, Rhodian envoys appeared at the Roman head-quarters and in the Roman senate, announcing that the Rhodians would no longer tolerate this war which was injurious to their Macedonian traffic and their revenue from port-dues, that they were disposed themselves to declare war against the party which should refuse to make peace, and that with this view they had already concluded an alliance with Crete and with the Asiatic cities. Many caprices are possible in a republic governed by primary assemblies; but this insane intervention of a commercial city - which can only have been resolved on after the fall of the pass of Tempe was known at Rhodes - requires special explanation. The key to it is furnished by the well-attested account that the consul Quintus Marcius, that master of the "new-fashioned diplomacy", had in the camp at Heracleum (and therefore after the occupation of the pass of Tempe) loaded the Rhodian envoy Agepolis with civilities and made an underhand request to him to mediate a peace. Republican wrongheadedness and vanity did the rest; the Rhodians fancied that the Romans had given themselves up as lost; they were eager to play the part of mediator among four great powers at once; communications were entered into with Perseus; Rhodian envoys with Macedonian sympathies said more than they should have said; and they were caught. The senate, which doubtless was itself for the most part unaware of those intrigues, heard the strange announcement, as may be conceived, with indignation, and was glad of the favourable opportunity to humble the haughty mercantile city. A warlike praetor went even so far as to propose to the people a declaration of war against Rhodes. In vain the Rhodian ambassadors repeatedly on their knees adjured the senate to think of the friendship of a hundred and forty years rather than of the one offence; in vain they sent the heads of the Macedonian party to the scaffold or to Rome; in vain they sent a massive wreath of gold in token of their gratitude for the non-declaration of war. The upright Cato indeed showed that strictly the Rhodians had committed no offence and asked whether the Romans were desirous to undertake the punishment of wishes and thoughts, and whether they could blame the nations for being apprehensive that Rome might allow herself all license if she had no longer any one to fear? His words and warnings were in vain. The senate deprived the Rhodians of their possessions on the mainland, which yielded a yearly produce of 120 talents (29,000 pounds). Still heavier were the blows aimed at the Rhodian commerce. The very prohibition of the import of salt to, and of the export of shipbuilding timber from, Macedonia appears to have been directed against Rhodes. Rhodian commerce was still more directly affected by the erection of the free port at Delos; the Rhodian customs-dues, which hitherto had produced 1,000,000 drachmae (41,000 pounds) annually, sank in a very brief period to 150,000 drachmae (6180 pounds). Generally, the Rhodians were paralyzed in their freedom of action and in their liberal and bold commercial policy, and the state began to languish. Even the alliance asked for was at first refused, and was only renewed in 590 after urgent entreaties. The equally guilty but powerless Cretans escaped with a sharp rebuke.
