He was therefore an eunuch, but having been well educated he was thought worthy of this trust. He continued for [CAS. 623] some time well affected to Lysimachus, but upon a disagreement with Arsinoë, the wife of Lysimachus, who had falsely accused him, he caused the place to revolt, and suited his political conduct to the times, perceiving them to be favourable to change. Lysimachus, overwhelmed with domestic troubles, was compelled to put to death Agathocles his son. Seleucus Nicator invaded his country and destroyed his power, but was himself treacherously slain by Ptolemy Ceraunus. During these disorders the eunuch remained in the fortress, continually employing the policy of promises and other courtesies with those who were the strongest and the nearest to himself. He thus continued master of the stronghold for twenty years. 2. He had two brothers, the elder of whom was Eumenes, the younger Attalus. Eumenes had a son of the same name, who succeeded to the possession of Pergamum, and was then sovereign of the places around, so that he overcame in a battle near Sardes[1528] Antiochus, the son of Seleucus, and died after a reign of two-and-twenty years. Attalus, the son of Attalus and Antiochis, daughter of Achæus, succeeded to the kingdom. He was the first person who was proclaimed king after a victory, which he obtained in a great battle with the Galatians. He became an ally of the Romans, and, in conjunction with the Rhodian fleet, assisted them in the war against Philip. He died in old age, having reigned forty-three years. He left four sons by Apollonis, a woman of Cyzicus,--Eumenes, Attalus, Philetærus, and Athenæus. The younger sons continued in a private station, but Eumenes, the elder, was king. He was an ally of the Romans in the war with Antiochus the Great, and with Perseus; he received from the Romans all the country within the Taurus which had belonged to Antiochus. Before this time there were not under the power of Pergamum many places which reached the sea at the Elaïtic and the Adramyttene Gulfs. Eumenes embellished the city, he ornamented the Nicephorium[1529] with a grove, enriched it with votive offerings and a library, and by his care raised the city of Pergamum to its present magnificence. After he had reigned forty-nine years he left the kingdom to Attalus, his son by Stratonice, daughter of Ariarathus, king of Cappadocia.
