As Prusias was hated by his subjects on account of his extreme cruelty they became greatly attached to his son, Nicomedes. Thus the latter fell under the suspicion of Prusias, who sent him to live in Rome. Learning that he
was much esteemed there also, Prusias directed him to
petition the Senate to release him from the payment of the money still due to Attalus. He sent Menas as his fellow-ambassador, and told him if he should secure a remission of the payments to spare Nicomedes, but if not, to kill him at Rome. For this purpose he sent a number of small boats with him and 2000 soldiers. As the fine imposed on Prusias was not remitted (for Andronicus, who had been sent by Attalus to argue on the other side, showed that it was less in amount than the plunder), Menas, seeing that Nicomedes was an estimable and attractive young man, was at a loss to know what to do. He did not dare to kill him, nor to go back himself to Bithynia. The young man noticed his delay and sought a conference with him, which was just what he wanted. They formed a plot against Prusias and secured the coöperation of Andronicus, the legate of Attalus, that he should persuade Attalus to take back Nicomedes to Bithynia. They met by agreement at Bernice, a small town in Epirus, where they entered into a ship by night to confer as to what should be done, and separated before daylight.
