The earliest historical person who probably belongs to the Aleuadae is the general Eurylochus, who terminated the First Sacred War about 590 BC. 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 Simus; but besides the suggestion of Ovid 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.
