Here ends the legend of the beautiful Antiopê and her twin sons—the rude and unpolished, but energetic, Zêthus—and the refined and amiable, but dreamy, Amphiôn. For so Euripidês, in the drama of Antiopê unfortunately lost, presented the two brothers, in affectionate union as well as in striking contrast.[633] It is evident that the whole story stood originally quite apart from the Kadmeian family, and so the rudiments of it yet stand in the Odyssey; but the logographers, by their ordinary connecting artifices, have opened a vacant place for it in the descending series of Thêban mythes. And they have here proceeded in a manner not usual with them. For whereas they are generally fond of multiplying entities, and supposing different historical personages of the same name, in order to introduce an apparent smoothness in the chronology—they have here blended into one person Amphiôn the son of Antiopê and Amphiôn the father of Chlôris, who seem clearly distinguished from each other in the Odyssey. They have further assigned to the same person all the circumstances of the legend of Niobê, which seems to have been originally framed quite apart from the sons of Antiopê. [633] See Valckenaer. Diatribe in Eurip. Reliq. cap. 7, p. 58; Welcker, Griechisch. Tragöd. ii. p. 811. There is a striking resemblance between the Antiopê of Euripidês and the Tyrô of Sophoklês in many points. Plato in his Gorgias has preserved a few fragments, and a tolerably clear general idea of the characters of Zêthus and Amphiôn (Gorg. 90-92); see also Horat. Epist. i. 18, 42. Both Livius and Pacuvius had tragedies on the scheme of this of Euripidês, the former seemingly a translation.
