and unwilling to return to Argos, which had been the principality of Akrisios, Perseus made an exchange with Megapenthês, son of Prœtos king of Tiryns. Megapenthês became king of Argos, and Perseus of Tiryns: moreover, the latter founded, within ten miles of Argos, the far-famed city of Mykênæ. The massive walls of this city, like those of Tiryns, of which remains are yet to be seen, were built for him by the Lykian Cyclôpes.[198] [197] The beautiful fragment of Simonidês (Fragm. vii. ed. Gaisford. Poet. Min.), describing Danaê and the child thus exposed, is familiar to every classical reader. [198] Paus. ii. 15, 4; ii. 16, 5. Apollod. ii. 2. Pherekyd. Fragm. 26, Dind. We here reach the commencement of the Perseid dynasty of Mykênæ. It should be noticed, however, that there were among the ancient legends contradictory accounts of the foundation of this city. Both the Odyssey and the Great Eoiai enumerated, among the heroines, Mykênê, the Eponyma of the city; the former poem classifying her with Tyrô and Alkmênê, the latter describing her as the daughter of Inachus and wife of Arestôr. And Akusilaus mentioned an Eponymus Mykêneus, the son of Spartôn and grandson of Phorôneus.[199] [199] Odyss. ii. 120. Hesiod. Fragment. 154. Marktscheff.—Akusil. Fragm. 16. Pausan. ii. 16, 4. Hekatæus derived the name of the town from the μύκης of the sword of Perseus (Fragm. 360, Dind.). The Schol. ad Eurip. Orest. 1247, mentions Mykêneus as son of Spartôn, but grandson of Phêgeus the brother of Phorôneus. The prophetic family of Melampus maintained itself in one of the three parts of the divided Argeian kingdom for five generations, down to Amphiaraos and his sons Alkmæôn and Amphilochos. The dynasty of his brother Bias, and that of Megapenthês, son of Prœtos, continued each for four generations: a list of barren names fills up the interval.[200] The Perseids of Mykênæ boasted a descent long and glorious, heroic as well as historical, continuing down to the last sovereigns of Sparta.[201] The issue of Perseus was numerous: his son Alkæos was father of Amphitryôn; another of his sons, Elektryôn, was father of Alkmênê;[202] a third, Sthenelos, father of Eurystheus. [200] Pausan. ii. 18, 4. [201] Herodot. vi. 53. [202] In the Hesiodic Shield of Hêraklês, Alkmênê is distinctly mentioned as daughter of Elektryôn; the genealogical poet, Asios, called her the daughter of Amphiaraos and Eriphyle (Asii Fragm. 4, ed. Markt. p. 412). The date of Asios cannot be precisely fixed; but he may be probably assigned to an epoch between the 30th and 40th Olympiad. Asios must have adopted a totally different legend respecting the birth of Hêraklês and the circumstances preceding it, among which the deaths of her father and brothers are highly influential. Nor could he have accepted the received chronology of the sieges of Thêbes and Troy.
