Ba'brius（*Ba/brios), or BA'BRIAS (Βαβρίας), sometimes also called GA'BRIAS (Γαβρίας), who is not a different person from Babrius, as Bentley supposed, a Greek poet, who after the example of Socrates turned the Aesopean fables into verse. The emperor Julian (Ep. 90) is the first writer who mentions Babrius; but as some of Babrius's verses are quoted by Apollonius in his Homeric Lexicon (s. v. ἄειδε), though without mentioning his name, he lived in all probability before the time of Augustus. [APOLLONIUS, No. 5.] This is in accordance with the account of Avianus, who speaks (Praef.) of Babrius before Phaedrus.
Μύθοι and Μυθίαμβοι, and was comprised in ten books according to Suidas (s. v. Βάβριος), or two volumes (volumina) according to Avianus. His version, which is one of no ordinary merit, seems to have been the basis of all the Aesopean fables which have come down to us in various forms. Later writers of Aesopean fables, such as Maximus Planudes, probably turned the poems of Babrius into prose, but they did it in so clumsy a manner, that many choliambic verses may still be traced in their fables, as Bentley has shewn in his dissertation on Aesop's fables. [AESOPUS, p. 48a.] Bentley was the first writer who called the attention of the learned to this fact, which was proved still more clearly by Tyrwhitt in his dissertation " De Babrio, Fabularum Aesopearum Scriptore," Lond. 1776, reprinted at Erlangen, 1785, ed. Harles.
