These terms of praise, it must be confessed, cannot be bestowed on all the fables in this collection. Many of them lack that unity of design, that close connection of the moral with the narrative, that wise choice in the introduction of the animals, which constitute the charm and excellency of true Æsopian fable. This inferiority of some to others is sufficiently accounted for in the history of the origin and descent of these fables. The great bulk of them are not the immediate work of Æsop. Many are obtained from ancient authors prior to the time in which he lived. Thus, the fable of the “Hawk and the Nightingale” is related by Hesiod;[4] the “Eagle wounded by an Arrow, winged with its own feathers,” by Æschylus;[5] the “Fox avenging his wrongs on the Eagle,” by Archilochus.[6] Many of them again are of later origin, and are to be traced to the monks of the middle ages: and yet this collection, though thus made up of fables both earlier and later than the era of Æsop, rightfully bears his name, because he composed so large a number (all framed in the same mould, and conformed to the same fashion, and stamped with the same lineaments, image, and superscription) as to secure to himself the right to be considered the father of Greek fables, and the founder of this class of writing, which has ever since borne his name, and has secured for him, through all succeeding ages, the position of the first of moralists.[7] The fables were in the first instance only narrated by Æsop, and for a long time were handed down by the uncertain channel of oral tradition. Socrates is mentioned by Plato[8] as having employed his time while in prison, awaiting the return of the sacred ship from Delphos which was to be the signal of his death, in turning some of these fables into verse, but he thus versified only such as he remembered. Demetrius Phalereus, a philosopher at Athens about 300 B.C., is said to have made the first collection of these fables. Phædrus, a slave by birth or by subsequent misfortunes, and admitted by Augustus to the honours of a freedman, imitated many of these fables in Latin iambics about the commencement of the Christian era. Aphthonius, a rhetorician of Antioch, A.D. 315, wrote a treatise on, and converted into Latin prose, some of these fables. This translation is the more worthy of notice, as it illustrates a custom of common use, both in these and in later times. The rhetoricians and philosophers were accustomed to give the Fables of Æsop as an exercise to their scholars, not only inviting them to discuss the moral of the tale, but also to practice and to perfect themselves thereby in style and rules of grammar, by making for themselves new and various versions of the fables. Ausonius,[9] the friend of the Emperor Valentinian, and the latest poet of eminence in the Western Empire, has handed down some of these fables in verse, which Julianus Titianus, a contemporary writer of no great name, translated into prose.
