The exact date of the 'Suppliants' cannot be determined; but the simplicity of its plot, the lack of a prologue, the paucity of its characters, and the prominence of the Chorus, show that it is an early play. The scene is Argos. The Chorus consists of the daughters of Danaüs, and there are only three characters,--Danaüs, a Herald, and Pelasgus King of Argos. Danaüs and Aegyptus, brothers, and descendants of Io and Epaphus, had settled near Canopus at the mouth of the Nile. Aegyptus sought to unite his fifty sons in marriage with the fifty daughters of the brother. The daughters fled with their father to Argos. Here his play opens. The Chorus appeal for protection to the country, once the home of Io, and to its gods and heroes. Pelasgus, with the consent of the Argive people, grants them refuge, and at the end of the play repels the attempt to seize them made by the Herald of the sons of Aegyptus. A part of one of the choruses is of singular beauty, and it is doubtless to them that the preservation of the play is due. The play hardly seems to be a tragedy, for it ends without bloodshed. Further, it lacks dramatic interest, for the action almost stands still. It is a cantata rather than a tragedy. Both considerations, however, are sufficiently explained by the fact that this was the first play of a trilogy. The remaining plays must have furnished, in the death of forty-nine of the sons of Aegyptus, both action and tragedy in sufficient measure to satisfy the most exacting demands. The 'Seven Against Thebes' deals with the gloomy myth of the house of Laïus. The tetralogy to which it belonged consisted of the 'Laïus,' 'Oedipus,' 'Seven Against Thebes,' and 'Sphinx.' The themes of Greek tragedy were drawn from the national mythology, but the myths were treated with a free hand. In his portrayal of the fortunes of this doomed race, Aeschylus departed in important particulars, with gain in dramatic effect, from the story as it is read in Homer.
