For the memory of Alexander’s greatness had always served the Romans as a reproach. Even worse, it provided an inspiration to their foes. In the east the model of kingship established by Alexander had never lost its allure.

Hence its appeal to monarchs, such as Mithridates, who were not even Greek, and hence, most startling of all, its appeal to bandits and rebellious slaves.
