From Scepsis came also Demetrius, whom I often mention, the grammarian who wrote a commentary on ''The Marshalling of the Trojan Forces'', and was born at about the same time as Crates and Aristarchus; and later, Metrodorus, a man who changed from his pursuit of philosophy to political life, and taught rhetoric, for the most part, in his written works; and he used a brand-new style and dazzled many. On account of his reputation he succeeded, though a poor man, in marrying brilliantly in Chalcedon; and he passed for a Chalcedonian. And having paid court to Mithridates Eupator, he with his wife sailed away with him to Pontus; and he was treated with exceptional honor, being appointed to the judgeship from which there was no appeal to the king. However, his good fortune did not continue, but he incurred the enmity of men less just than himself and revolted from the king when he was on the embassy to Tigranes the Armenian. And Tigranes sent him back against his will to Eupator, who was already in flight from his ancestral realm; but Metrodorus died on the way, whether by order of the king or from disease; for both accounts are given of his death. So much for the Scepsians.〔Strabo, Geography, Bk. XIII, Ch.1, 55 (English translation in edition ed. by H.C. Hamilton, Esq., W. Falconer, M.A.) Strabo is an important source for information on Metrodorus, as he was a near-contemporary (writing approximately 70 years after the time of Metrodorus) and a native of Amasya, the old capitol of the Pontic kings.〕

Up to this time Tigranes had not deigned to see Mithridates, nor speak to him, though the man was allied to him by marriage,〔Mithridates' daughter Cleopatra had married Tigranes to cement an alliance in 94 BC.〕 and had been expelled from such a great kingdom. Instead, he had kept him at the farthest remove possible, in disgrace and contumely, and had suffered him to be held a sort of prisoner in marshy and sickly regions. Now, however, he summoned him to his palace with marks of esteem and friendship. There, in secret conference, they strove to allay their mutual suspicions at the expense of their friends, by laying the blame upon them. One of these was Metrodorus of Scepsis, a man of agreeable speech and wide learning, who enjoyed the friendship of Mithridates in such a high degree that he was called the king's father. This man, as it seems, had once been sent as an ambassador from Mithridates to Tigranes, with a request for aid against the Romans. On this occasion Tigranes asked him: "But what is your own advice to me, Metrodorus, in this matter?" Whereupon Metrodorus, either with an eye to the interests of Tigranes, or because he did not wish Mithridates to be saved, said that as an ambassador he urged consent, but as an adviser he forbade it. Tigranes disclosed this to Mithridates, not supposing, when he told him, that he would punish Metrodorus past all healing. But Metrodorus was at once put out of the way. Then Tigranes repented of what he had done, although he was not entirely to blame for the death of Metrodorus. He merely gave an impulse, as it were, to the hatred which Mithridates already had for the man. For he had long been secretly hostile to him, as was seen from his private papers when they were captured, in which there were directions that Metrodorus, as well as others, be put to death. Accordingly, Tigranes gave the body of Metrodorus a splendid burial, sparing no expense upon the man when dead, although he had betrayed him when alive.〔Plutarch, The Parallel Lives, Life of Lucullus, English translation from Loeb Edition of 1914〕

Scepsian Metrodorus attacked Italian ways, not the land, in bitter writing: and Rome itself was accused of guilt: yet Rome accepted the lying invective equably, and the author’s wild speech did him no harm.〔Ovid, Epistulae ex ponto, Bk. IV, Ch. xiv〕

Although I was thirsting for them, I barely tasted the arts I am speaking of when I was a quaestor in Asia, where I obtained a near contemporary of mine, a rhetor from the Academy – the Metrodorus whose memory Antoninus was recalling...
