a Thessalian, the minister and friend of Pyrrhus king of Epirus. He was sent to Rome after the battle of Heraclea to sue for a peace, but was foiled in his mission through the eloquence of Appius Cæcilius. He told Pyrrhus that the Roman senate was a venerable assembly of kings; and that to fight with them was to fight against another Hydra. He was a man of consummate address, and possessed a memory so retentive that the day after his arrival at Rome he could call every senator and knight by name. His last diplomatic mission was to Sicily, B.C. 278; and with his death the fortunes of Pyrrhus began to decline.
