Mithridates, the king against whom Sulla went to fight in 87 B.C., was a brave and skilful commander. His kingdom, Cappadocia Pontica, was a district on the south shore of the Black Sea. The king who ruled before Mithridates came to the throne had tried to enlarge his kingdom, but more than once the Romans had thwarted his ambitious plans. When Mithridates began to reign in 111 B.C., he knew that no one save the Romans would be strong enough to keep him from adding to his kingdom. The king proved himself so strong and so good a general that the Greek towns in Asia Minor resolved to throw aside the friendship of Rome and ally themselves with the King of Pontus. It was this revolt that Sulla, with his five legions, went to Greece to subdue. It was ungrateful of Athens to forsake Rome, for she had been treated most honourably by her in the past, and still was enjoying many privileges when she rebelled. But the Athenians wished their city to be more glorious in the future than she had been even in the past, and they believed that Mithridates would help them to achieve this better than Rome. So an ambassador named Aristion was sent to the King of Pontus to offer him the friendship of Athens. The king received Aristion with great respect, and gave to him gifts of gold. Above all, when he took leave of Mithridates, he was presented with a ring, on which was engraved a portrait of the king himself. When the ambassador returned to Athens and showed the gifts which he had received, the enthusiasm of the people knew no bounds. He was escorted by crowds to the Peiræus, the port of Athens. Here, in the citadel, he was asked to tell what had taken place at the court of the king. Now Aristion was a great orator, and he knew that his words would influence the people to do as he wished. So first he reminded them of all the wrongs that Athens had suffered from the Romans, and if these wrongs were not all real, Aristion made them seem so by his eloquence. Then he spoke of Mithridates, and of the king he had nothing but good to tell, while the magnificence of his court, Aristion modestly declared, baffled even his powers of description. Before Aristion had finished his oration, the magistrates of Athens had determined to proclaim their republic restored, and to form an alliance with Mithridates. Aristion was appointed chief minister of war, and you shall hear how sadly he failed to do his duty when trouble befell the city. Sulla having landed with his army at Epirus, at once marched to Athens, for by this time both the city and the Peiræus were strongly fortified, and held by Archelaus, the general of Mithridates. The Roman commander determined to besiege the citadel, and to surround Athens with soldiers, to prevent the citizens from escaping, or provisions from being sent to their relief. As he had neither money nor material for the siege, Sulla robbed the temples of Greece of their treasures.
