The surviving text of the fragmentary Phaethon of Euripides depends chiefly on two sources: two pages from a Euripidean manuscript, written about A. D. 500, and a papyrus of the third century B. C. , which contains a substantial part of the parodos. These sources are supplemented by a number of citations in classical authors and by a recently published fragmentary hypothesis. Professor Diggle has examined all the manuscript evidence and offers many decipherments. He gives a text of the play and of the hypothesis, an exegetical commentary, prolegomena and appendices, in which he discusses the treatment of the Phaethon myth in classical literature and attempts a reconstruction of the plot of the play.
