with a grace and charm that are strikingly absent from the rest of his writing, the picture of his own quiet life as a student, and of the awakening of his moral and intellectual nature at the touch of philosophy. Lucan and Persius represent the effect which Roman Stoicism had on two natures of equal sensibility but widely different quality and taste. Among the many other professors or adherents of the Stoic school in the age of Nero, a considerable number were also authors, but the habit of writing in Greek, which a hundred years later grew to such proportions as to threaten the continued existence of Latin literature, had already taken root. The three most distinguished representatives of the stricter Stoicism, Cornutus, Quintus Sextius, and Gaius Musonius Rufus (the first and last of whom were exiled by Nero), wrote on philosophy in Greek, though they seem to have written in Latin on other subjects. Musonius was, indeed, hardly more Roman than his own most illustrious pupil, the Phrygian Epictetus. Stoicism, as they understood it, left no room for nationality, and little for writing as a fine art. This growing prevalence of Greek at Rome combined with political reasons to check the production of important prose works. History more especially languished under the jealous censorship of the government. The only important historical work of the period is one of which the subject could hardly excite suspicion, the _Life of Alexander the Great_, by Quintus Curtius Rufus. The precise date is uncertain, and different theories have assigned it to an earlier or later period in the reign of Augustus or of Vespasian. The subject is one which hardly any degree of dulness in the writer could make wholly uninteresting. But the clear and orderly narrative of Curtius, written in a style studied from that of Livy, but kept within simpler limits, has real merit of its own; and against his imperfect technical knowledge of strategy and tactics must be set the pains he took to consult the best Greek authorities.
