Alexander of Macedon, having despatched this Darius, during this period, began to reign. Similarly, therefore, the times of the Macedonian kings are thus computed: Alexander, eighteen years; Ptolemy the son of Lagus, forty years; Ptolemy Philadelphus, twenty-seven years; then Euergetes, five-and-twenty years; then Philopator, seventeen years; then Epiphanes, four-and-twenty years; he was succeeded by Philometer, who reigned five-and-thirty years; after him Physcon, twenty-nine years; then Lathurus, thirty-six years; then he that was surnamed Dionysus, twenty-nine years; and last Cleopatra reigned twenty-two years. And after her was the reign of the Cappadocians for eighteen days.
