) II., king of PERGAMUS son of Attalus I., whom he succeeded on the throne B. C. 197. (Clinton, F. H.
iii. p. 403.)
He inherited from his predecessor the friendship and alliance of the Romans, which he took the utmost pains to cultivate, and was included by them in the treaty of peace concluded with Philip, king of Macedonia, in 196, by which he obtained possession of the towns of Oreus and Eretria in Euboea. (Liv. 33.30
In the following year he sent a fleet to the assistance of Flamininus in the war against Nabis. (Liv. 34.26
.) His alliance was in vain courted by his powerful neighbour, Antiochus III., who offered him one of his daughters in marriage. (Appian, App. Syr. 5
.) Eumenes plainly saw that it was his interest to adhere to the Romans in the approaching contest; and far from seeking to avert this, he used all his endeavours to urge on the Romans to engage in it. When hostilities had actually commenced, he was active in the service of his allies, both by sending his fleet to support that of the Romans under Livius and Aemilius, and facilitating the important passage of the Hellespont.
In the decisive battle of Magnesia (B. C. 190), he commanded in person the troops which he furnished as auxiliaries to the Roman army, and appears to have rendered valuable services. (Liv. 35.13
, xxxvii, 14, 18, 33, 37, 41; Appian, App. Syr. 22
; Justin, 31.8
.) Immediately on the conclusion of peace, lie hastened to Rome, to put forward in person his claims to reward : his pretensions were favourably received by the senate, who granted him the possession of Mysia, Lydia, both Phrygias, and Lycaonia, as well as of Lysimachia, and the Thracian Chersonese.
By this means Eumenes found himself raised at once from a state of comparative insignificance to be the sovereign of a powerful monarchy. (Liv. 37.45
; Plb. 22.1
; Appian, App. Syr. 44
.) About the same time, he married the daughter of Ariarathes, king of Cappadocia, and procured from the Romans favourable terms for that monarch. (Liv. 38.39
This alliance was the occasion of involving him in a war with Pharnaces, king of Pontus, who had invaded Cappadocia, but which was ultimately terminated by the intervention of Rome. (Plb. 25.2
He was also engaged in hostilities with Prusias, king of Bithynia, which gave the Romans a pretext for interfering, not only to protect Eumenes, but to compel Prusias to give up Hannibal, who had taken refuge at his court. (Liv. 39.46
; Just. 32.4
; Corn. Nep. Hann.
During all this period, Eumnenes enjoyed the highest favour at Rome, and certainly was not backward in availing himself of it.
He was continually sending embassies thither, partly to cultivate the good understanding with the senate in which he now found himself, but frequently also to complain of the conduct of his neighbours, especially of the Macedonian kings, Philip and his successor, Perseus. In 172, to give more weight to his remonstrances, he a second time visited Rome in person, where he was received with the utmost distinction. On his return from thence, he visited Delphi, where he narrowly escaped a design against his life formed by the emissaries of Perseus. (Liv. 42.11
; Diod. Exc. Leg.
p. 623, Exc. Vales.
p. 577; Appian, Mac. Exc.
9, pp. 519-526, ed. Schweigh.)
But though he was thus apparently on terms of the bitterest hostility with. the Macedonian monarch, his conduct during the war that followed was not such as to give satisfaction to the Romans; and he was suspected of corresponding secretly with Perseus, a charge which, accordinig to Polybius, was not altogether unfounded; but his designs extended only to the obtaining from that prince a sum of money for procuring him a peace on favourable terms. (Polyb. Fragm. Vatican.
pp. 427-429; Liv. 44.13
; Appian, Mac. Exc.
16, pp. 531-2.) His overtures were, however, rejected by Perseus, and after the victory of the Romans (B. C. 167), he hastened to send his brother Attalus to the senate with his congratulations. They did not choose to take any public notice of what had passed, and dismissed Attalus with fair words; but when Eumenes, probably alarmed at finding his schemes discovered, determined to proceed to Rome in person, the senate passed a decree to forbid it, and finding that he was already arrived at Brundusium, ordered him to quit Italy without delay. (Plb. 30.17
, Fragm. Vatic.
p. 428; Liv. Epit.
xlvi.) Henceforward he was constantly regarded with suspicion by the Roman senate, and though his brother Attalus, whom he sent to Rome again in B. C. 160, was received with marked favour, this seems to have been for the very purpose of exciting him against Eumenes, who had sent him, and inducing him to set up for himself. (Plb. 32.5
The last years of the reign of Eumenes seem to have been disturbed by frequent hostilities on the part of Prusias, king of Bithynia, and the Gauls of Galatia; but he had the good-fortune or dexterity to avoid coming to an open rupture either with Rome or his brother Attalus. (Plb. 31.9
; Diod. xxxi. Exc. Vales.
p. 582.) His death, which is not mentioned by any ancient writer, must have taken place in B. C. 159, after a reign of 39 years. (Strab. xiii. p.624
; Clinton, F. H.
iii. pp. 403, 406.)
According to Polybius (32.23
), Eumenes was a man of a feeble bodily constitution, but of great vigour and power of mind, which is indeed sufficiently evinced by the history of his reign: his policy was indeed crafty and temporizing, but indicative of much sagacity; and he raised his kingdom from a petty state to one of the highest consideration. All the arts of peace were assiduously protected by him: Pergamus itself became under his rule a great and flourishing city, which he adorned with splendid buildings, and in which he founded that celebrated library which rose to be a rival even to that of Alexandria. (Strab. xiii. p.624
It would be unjust to Eumenes not to add the circumstance mentioned by Polybius in his praise, that he continued throughout his life on the best terms with all his three brothers, who cheerfully lent their services to support him in his power. One of these, Attalus, was his immediate successor, his son Attalus being yet an infant. (Plb. 32.23
; Strab. xiii. p.624
