Mithridatic Wars (1.5-1.6)

In the morning Nicomedes came out of the ship clad in the royal purple and wearing a diadem on his head. Andronicus met him, saluted him as king, and formed an escort for him with 500 soldiers that he had with him. Menas, pretending that he had then for the first time learned that Nicomedes was present, rushed to his 2000 men and exclaimed with assumed trepidation, "Since we have two kings, one at home and the other going there, we must look out for our own interests, and form a careful judgment of the future, because our safety lies in foreseeing correctly which of them will be the stronger. One of them is an old man, the other is young. The Bithynians are averse to Prusias; they are attached to Nicomedes. The leading Romans are fond of the young man, and Andronicus has already furnished him a guard, showing that Nicomedes is in alliance with Attalus, who rules an extensive dominion alongside the Bithynians and is an old enemy of Prusias." In addition to this he expatiated on the cruelty of Prusias and his outrageous conduct toward everybody, and the general hatred in which he was held by the Bithynians on this account. When he saw that the soldiers also abhorred the wickedness of Prusias he led them forthwith to Nicomedes and saluted him as king, just as Andronicus had done before, and formed a guard for him with his 2000 men.

Attalus received the young man warmly and ordered Prusias to assign certain towns for his occupation, and territory to furnish him supplies. Prusias replied that he would presently give his son the whole kingdom of Attalus, which he had intended for Nicomedes when he invaded Asia[*] before. After giving this answer he made a formal accusation at Rome against Nicomedes and Attalus and cited them to trial. The forces of Attalus at once made an incursion into Bithynia, the inhabitants of which gradually took sides with the invaders. Prusias, trusting nobody and hoping that the Romans would rescue him from the toils of the conspiracy, asked and obtained from his son-in-law, Diegylis, the Thracian, 500 men, and with these alone as a body-guard he took refuge in the citadel of Nictæa. The Roman prætor, in order to favor Attalus, delayed introducing the ambassadors of Prusias to the Senate at Rome. When he did introduce them, the Senate voted that the prætor himself should choose legates and send them to settle the difficulty. He selected three men, one of whom had once been struck on the head with a stone, from which he was badly scarred; another was a diseased cripple, and the third was considered almost a fool; wherefore Cato made the contemptuous remark concerning this embassy, that it had no understanding, no feet and no head.
