They say that Phœnix was the instructor of Achilles, and Adrastus of the children of Crœsus; and Leonides of Alexander, and Nausithous of Philip. But Phœnix was women-mad, Adrastus was a fugitive. Leonides did not curtail the pride of Alexander, nor Nausithous reform the drunken Pellæan. No more was the Thracian Zopyrus able to check the fornication of Alcibiades; but Zopyrus was a bought slave, and Ticinnus, the tutor of the children of Themistocles, was a lazy domestic. They say also that he invented the Sicinnian dance. Those have not escaped our attention who are called royal instructors among the Persians; whom, in number four, the kings of the Persians select with the greatest care from all the Persians, and set over their sons. But the children only learn the use of the bow, and on reaching maturity have sexual intercourse with sisters, and mothers, and women, wives and courtesans innumerable, practised in intercourse like the wild boars.
