Aesop must have received his freedom from Iadmon, or he could not have conducted the public defence of a certain Samian demagogue (Aristotle, Rhetoric, ii. 20). According to the story, he subsequently lived at the court of Croesus, where he met Solon, and dined in the company of the Seven Sages of Greece with Periander at Corinth. During the reign of Peisistratus[?] he is said to have visited Athens, on which occasion he related the fable of The Frogs asking for a King, to dissuade the citizens from attempting to exchange Peisistratus[?] for another ruler. The popular stories current regarding him are derived from a life, or rather romance, prefixed to a book of fables, purporting to be his, collected by Maximus Planudes, a monk of the 14th century. In this he is described as a monster of ugliness and deformity, as he is also represented in a well-known marble figure in the Villa Albani at Rome. That this life, however, was in existence a century before Planudes, appears from a 13th-century manuscript of it found at Florence. In Plutarch's Symposium of the Seven Sages, at which Aesop is a guest, there are many jests on his original servile condition, but nothing derogatory is said about his personal appearance. We are further told that the Athenians erected in his honour a noble statue by the famous sculptor Lysippus[?], which furnishes a strong argument against the fiction of his deformity. Lastly, the obscurity in which the history of Aesop is involved has induced some scholars to deny his existence altogether.
It is probable that Aesop did not commit his fables to writing; Aristophanes (Wasps, 1259) represents Philocleon as having learnt the "absurdities" of Aesop from conversation at banquets) and Socrates whiles away his time in prison by turning some of Aesop's fables "which he knew" into verse (Plato, Phaedo, 61 b). Demetrius of Phalerum[?] (345-283 B.C.) made a collection in ten books, probably in prose (Lopson Aisopeion sunagogai) for the use of orators, which has been lost. Next appeared an edition in elegiac verse, often cited by Suidas, but the author's name is unknown. Babrius, according to Crusius, a Roman and tutor to the son of Alexander Severus, turned the fables into choliambics in the earlier part of the 3rd century A.D. The most celebrated of the Latin adapters is Phaedrus, a freedman of Augustus. Avianus (of uncertain date, perhaps the 4th century) translated 42 of the fables into Latin elegiacs.
The collections which we possess under the name of Aesop's Fables are late renderings of Babrius's Version or Progumnasmata, rhetorical exercises of varying age and merit. Syntipas translated Babrius into Syriac, and Andreopulos put the Syriac back again into Greek. Ignatius Diaconus, in the 9th century, made a version of 55 fables in choliambic tetrameters. Stories from Oriental sources were added, and from these collections Maximus Planudes made and edited the collection which has come down to us under the name of Aesop, and from which the popular fables of modern Europe have been derived.

The history of the Aesopic fable; ii. The Fables of Aesop, as first printed by William Caxton, 1484, from his French translation; Hervieux, Les Fabulistes Latins (1893-1899). Before any Greek text appeared, a Latin translation of 100 Fabulae Aesopicae by an Italian scholar named Ranuzio (Renutius) was published at Rome, 1476. About 1480 the collection of Planudes was brought out at Milan by Buono Accorso (Accursius), together with Ranuzio's translation. This edition, which contained 144 fables, was frequently reprinted and additions made from time to time from various manuscripts.--the Heidelberg (Palatine), Florentine, Vatican and Augsburg---by Stephanus (1547), Nevelet (1610), Hudson (1718), Hauptmann (1741), Furia (1810), Coray (1810), Schneider (1812) and others. A critical edition of all the previously known fables, prepared by Carl von Halm from the collections of Furia, Coray and Schneider, was published in the Teubner series of Greek and Latin texts. A Fabularum Aesopicarum sylloge (233 in number) from a Paris manuscript, with critical notes by Sternbach, appeared in a Cracow University publication, Rozprawy akademii umiejetinosci (1894).
