A Dictionary of Greek and Roman biography and mythology

12. Wife and also sister of Mithridates Eupator (commonly called the Great), king of Pontus. During the absence of her husband, and deceived by a report of his death, she gave free scope to her amours; and, alarmed for the consequences, on his return attempted his life by poison. Her designs were, however, betrayed to Mithridates, who immediately put her to death. (Just. 37.3.)
