Gaius Julius Phaedrus (/ˈfiːdrəs/; Greek: Φαῖδρος; Phaîdros) was a 1st-century CE Roman fabulist and the first versifier of a collection of Aesop’s fables into Latin. Few facts are known about him for certain and there was little mention of his work during late antiquity. It was not until the discovery of a few imperfect manuscripts during and following the Renaissance that his importance emerged, both as an author and in the transmission of the fables.
