<i>P.Oxy</i> . 2456 and the chronology of Euripides

Abstract The list of Euripidean plays in P.Oxy. 2456, whose primary principle of arrangement is by alphabetical order of first letter, has a secondary principle of arrangement, namely chronology of first performance date. This discovery provides a relative dating, and/or termini ante vel post quos , for 15 plays. The ordering in the papyrus is compared to orderings of other ancient lists of classical dramas, including a list of Aristophanes’ comedies whose arrangement by the same combination of principles was identified by Wilamowitz. A source for this arrangement is proposed, namely Callimachus’ Pinakes .
