and ALEU'ADAE (Ἀλεύας and Ἀλευάδαι). Aleuas is the ancestorial hero of the Thessalian, or, more particularly, of the Larissaean family of the Aleuadae. (Pind. P. 10.8, with the Schol.) The Aleuadae were the noblest and most powerful among all the families of Thessaly, whence Herodotus (7.6) calls its members Βασιλεῖς. (Comp. Diod. 15.61, 16.14.) The first Aleuas, who bore the surname of Πύρρος, that is, the red-haired, is called king (here synonymous with Tagus, see Dict. of Ant. p. 932) of Thessaly, and a descendant of Heracles through Thessalus, one of the many sons of Heracles. (Suidas, s. v. Ἀλευάδαι; Ulpian, ad Dem. Olynth. i.; Schol. (ad Apollon. Rhod. 3.1090; Vell. 1.3.) Plutarch (de Am. Frat. in, fin.) states, that he was hated by his father on account of his haughty and savage character; but his uncle nevertheless contrived to get him elected king and sanctioned by the god of Delphi. His reign was more glorious than that of any of his ancestors, and the nation rose in power and importance. This Aleuas, who belongs to the mythical period of Greek history, is in all probability the same as the one who, according to Hegemon (apud Ael. Anim. 8.11), was beloved by a dragon. According to Aristotle (apud Harpocrat. s.v. Τετραρχία) the division of Thessaly into four parts, of which traces remained down to the latest times, took place in the reign of the first Aleuas. Buttmann places this hero in the period between the so-called return of the Heraclids and the age of Peisistratus. But even earlier than the time of Peisistratus the family of the Aleuadac appears to have become divided into two branches, the Aleuadae and the Scopadae, called after Scopas, probably a son of Aleuas. (Ov. Ibis, 512.) The Scopadae inhabited Crannon and perhaps Pharsalus also, while the main branch, the Aleuadae, remained at Larissa. The influence of the families, however, was not confined to these towns, but extended more or less over the greater part of Thessaly. They formed in reality a powerful aristocratic party (Βασιλεῖς) in opposition to the great body of the Thessalians. (Hdt. 7.172.)
The earliest historical person, who probably belongs to the Aleuadae, is Eurylochus, who terminated the war of Cirrha about B. C. 590. (Strab. ix. p.418.) [EURYLOCHUS.] In the time of the poet Simonides we find a second Aleuas, who was a friend of the poet. He is called a son of Echecratides and Syris (Schol. ad Theocrit. 16.34); but besides the suggestion of Ovid (Ibis, 225), that he had a tragic end, nothing is known about him. At the time when Xerxes invaded Greece, three sons of this Aleuas, Thorax, Eurypylus, and Thrasydaeus, came to him as ambassadors, to request him to go on with the war, and to promise him their assistance. (Hdt. 7.6.) [THORAX.] When, after the Persian war, Leotychides was sent to Thessaly to chastise those who had acted as traitors to their country, he allowed himself to be bribed by the Aleuadae, although he might have subdued all Thessaly. (Hdt. 6.72; Paus. 3.7.8.) This fact shews that the power of the Alenadae was then still as great as before. About the year B. C. 460, we find an Aleuad Orestes, son of Echecratides, who came to Athens as a fugitive, and persuaded the Athenians to exert themselves for his restoration. (Thuc. 1.111.) He had been expelled either by the Thessalians or more probably by a faction of his own family, who wished to exclude him from the dignity of Βασιλεύς (i. e. probably Tagus), for such feuds among the Aleuadae themselves are frequently mentioned. (Xen.. Anab. 1.1.10.)
After the end of the Peloponnesian war, another Thessalian family, the dynasts of Pherae, gradually rose to power and influence, and gave a great shock to the power of the Aleuadae. As early as B. C. 375, Jason of Pherae, after various struggles, succeeded in raising himself to the dignity of Tagus. (Xen. Hell. 2.3.4; Diod. 14.82, 15.60.) When the dynasts of Pherae became tyrannical, some of the Larissaean Aleuadae conspired to put an end to their rule, and for this purpose they invited Alexander, king of Macedonia, the son of Amyntas. (Diod. 15.61.) Alexander took Larissa and Crannon, but kept them to himself. Afterwards, Pelopidas restored the original state of things in Thessaly; but the dynasts of Pherae soon recovered their power, and the Aleuadae again solicited the assistance of Macedonia against them. Philip willingly complied with the request, broke the power of the tyrants of Pherae, restored the towns to an appearance of freedom, and made the Alenadae his faithful friends and allies. (Diod. 16.14.) In what manner Philip used them for his purposes, and how little he spared them when it was his interest to do so, is sufficiently attested. (Dem. de Cor. p. 241; Polyaen. 4.2.11; Ulpian, l.c.) Among the tetrarchs whom he entrusted with the administration of Thessaly, there is one Thrasydaeus (Theopomp. apud Athen. vi. p. 249), who undoubtedly belonged to the Aleuadae, just as the Thessalian Medius, who is mentioned as one of
