An old enemy of Rome’s, Mithridates, kept attacking and retreating, attacking and retreating. Pompey, unable to finish him off, struck “across the desert for Petra . . . but midway, he was halted by dramatic news: Mithridates was dead. The old king had never given up on his defiance, but . . . when his son turned against him and blockaded him in his chambers, Rome’s arch-enemy had been cornered at last.”
Just to show how wily Mithridates was, he had slowly been building up an immunity to poison by ingesting it in small quantity, for many years. But when his son sided with Pompey, he attempted to poison himself. It didn’t work. He was finally “dispatched by one of the few things to which he had not cultivated an immunity, the sword point of a loyal guard.”
His body is carried back to Pompey by his son.
