But the kings who followed in this line soon lapsed into barbarism and became quite obscure, both in their power and in their lives, and it was Tharrhypas, historians say, who first introduced Greek customs and letters and regulated his cities by humane laws, thereby acquiring for himself a name. Alcetas was a son of Tharrhypas, Arybas of Alcetas, and of Arybas and Troas, Aeacides. He married Phthia, the daughter of Menon the Thessalian, a man who won high repute at the time of the Lamian war 323-322 B.C. See the Demosthenes , xxvii. 1 . and acquired the highest authority among the confederates after Leosthenes. Phthia bore to Aeacides two daughters, Deïdameia and Troas, and a son, Pyrrhus.
