The first line of the prologue recalled Laius' hubristic action of conceiving a son against Apollo's command. At some point in the action of the play, a character engaged in a lengthy and detailed description of the Sphinx and her riddle – preserved in five fragments from Oxyrhynchus, P.Oxy. 2459 (published by Eric Gardner Turner in 1962). The tragedy featured also many moral maxims on the theme of marriage, preserved in the Anthologion of Stobaeus. The most striking lines, however, state that in this play Oedipus was blinded by Laius' attendants, and that this happened before his identity as Laius' son had been discovered, therefore marking important differences with the Sophoclean treatment of the myth, which is now regarded as the 'standard' version. Many attempts have been made to reconstruct the plot of the play, but none of them is more than hypothetical, because of the scanty remains that survive from its text and of the total absence of ancient descriptions or résumés – though it has been suggested that a part of Hyginus' narration of the Oedipus myth might in fact derive from Euripides' play. Some echoes of the Euripidean Oedipus have been traced also in a scene of Seneca's Oedipus (see below), in which Oedipus himself describes to Jocasta his adventure with the Sphinx.
