Edward Gibbon, The Decline and Fall of the Roman Empire, Chp. XXII, Part III:
By a single edict, he reduced the palace of Constantinople to an immense desert, and dismissed with ignominy the whole train of slaves and dependants, without providing any just, or at least benevolent, exceptions, for the age, the services, or the poverty, of the faithful domestics of the Imperial family. Such indeed was the temper of Julian, who seldom recollected the fundamental maxim of Aristotle, that true virtue is placed at an equal distance between the opposite vices. The splendid and effeminate dress of the Asiatics, the curls and paint, the collars and bracelets, which had appeared so ridiculous in the person of Constantine, were consistently rejected by his philosophic successor. But with the fopperies, Julian affected to renounce the decencies of dress; and seemed to value himself for his neglect of the laws of cleanliness. In a satirical performance, which was designed for the public eye, the emperor descants with pleasure, and even with pride, on the length of his nails, and the inky blackness of his hands; protests, that although the greatest part of his body was covered with hair, the use of the razor was confined to his head alone; and celebrates, with visible complacency, the shaggy and populous beard, which he fondly cherished, after the example of the philosophers of Greece. Had Julian consulted the simple dictates of reason, the first magistrate of the Romans would have scorned the affectation of Diogenes, as well as that of Darius.
