The Alcestis

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 (there has been debate about his authorship of Rhesus, largely on stylistic grounds)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.-wikipedia
