"Philometor Euergetes" means "Loving-his-Mother, Benefactor" in Greek; he was so-called because of his close relationship with his mother Stratonice.
[1] According to Livy, Attalus III had little interest in ruling Pergamon, devoting his time to studying medicine, botany, gardening, and other pursuits.
[3] Tiberius Gracchus requested that the treasury of Pergamon be opened up to the Roman public, but the Senate refused this.
In 131 BC Aristonicus, who claimed to be Attalus' brother as well as the son of Eumenes II, an earlier king, led a popular uprising with the help of the Roman philosopher Blossius.
The revolt was put down in 129 BC, and Pergamon was divided among Rome, Pontus, and Cappadocia.
