The collection of fables in Greek verse by Babrias was exceedingly popular among the Romans. It was the favourite book of the Emperor Julian. Only six of these fables, and a few fragments, remain; but they are sufficient to show that their author possessed all the graces of style which befit the apologue. Some critics place him in the Augustan age; others make him contemporary with Moschus. His work was versified in Latin, at the instance of Seneca; and Quinctilian refers to it as a reading-book for boys. Thus, at all times, these playful fictions have been considered fit lessons for children, as well as for men, who are often but grown-up children. So popular were the fables of Babrias and their Latin translation, during the Roman empire, that the work of Phaedrus was hardly noticed. The latter was a freedman of Augustus, and wrote in the reign of Tiberius. His verse stands almost unrivalled for its exquisite elegance and compactness; and posterity has abundantly avenged him for the neglect of contemporaries. La Fontaine is perhaps more indebted to Phaedrus than to any other of his predecessors; and, especially in the first six books, his style has much of the same curious condensation. When the seat of the empire was transferred to Byzantium, the Greek language took precedence of the Latin; and the rhetorician Aphthonius wrote forty fables in Greek prose, which became popular. Besides these collections among the Romans, we find apologues scattered through the writings of their best poets and historians, and embalmed in those specimens of their oratory which have come down to us.
