Euripides was one of the three great tragedians of classical Athens, the other two being Aeschylus and Sophocles. Some ancient scholars attributed ninety-five plays to him but according to the Suda it was ninety-two at most. Of these, eighteen or nineteen have survived complete and there are also fragments, some substantial, of most of the other plays. More of his plays have survived intact than those of Aeschylus and Sophocles together, partly due to mere chance and partly because his popularity grew as theirs declined—he became, in the Hellenistic Age, a cornerstone of ancient literary education, along with Homer, Demosthenes and Menander.
Euripides is identified with theatrical innovations that have profoundly influenced drama down to modern times, especially in the representation of traditional, mythical heroes as ordinary people in extraordinary circumstances. This new approach led him to pioneer developments that later writers adapted to comedy, some of which are characteristic of romance. Yet he also became "the most tragic of poets", focusing on the inner lives and motives of his characters in a way previously unknown. He was "the creator of...that cage which is the theatre of Shakespeare's Othello, Racine's Phèdre, of Ibsen and Strindberg," in which "...imprisoned men and women destroy each other by the intensity of their loves and hates", and yet he was also the literary ancestor of comic dramatists as diverse as Menander and George Bernard Shaw.
