The death of Kleomenês, and the discredit thrown on his character, emboldened the Æginetans to prefer a complaint at Sparta respecting their ten hostages whom Kleomenês and Leotychidês had taken away from the island, a little before the invasion of Attica by the Persians under Datis, and deposited at Athens as guarantee to the Athenians against aggression from Ægina at that critical moment. Leotychidês was the surviving auxiliary of Kleomenês in the requisition of these hostages, and against him the Æginetans complained. Though the proceeding was one unquestionably beneficial to the general cause of Greece,[75] yet such was the actual displeasure of the Lacedæmonians against the deceased king and his acts, that the survivor Leotychidês was brought to a public trial, and condemned to be delivered up as prisoner in atonement to the Æginetans. The latter were about to carry away their prisoner, when a dignified Spartan named Theasidês, pointed out to them the danger which they were incurring by such an indignity against the regal person,—the Spartans, he observed, had passed sentence under feelings of temporary wrath, which would probably be exchanged for sympathy if they saw the sentence realized. [75] Herodot. vi, 61. Κλεομένεα, ἐόντα ἐν τῇ Αἰγίνῃ, καὶ κοινὰ τῇ Ἑλλάδι ἀγαθὰ προεργαζόμενον, etc. Accordingly the Æginetans, instead of executing the sentence, contented themselves with stipulating that Leotychidês should accompany them to Athens and redemand their hostages detained there. The Athenians refused to give up the hostages, in spite of the emphatic terms in which the Spartan king set forth the sacred obligation of restoring a deposit:[76] they justified the refusal in part by saying that the deposit had been lodged by the two kings jointly, and could not be surrendered to one of them alone: but they probably recollected that the hostages were placed less as a deposit than as a security against Æginetan hostility,—which security they were not disposed to forego. [76] Herodot. vi, 85: compare vi, 49-73, and the preceding volume of this history, c. xxxvi, pp. 437-441. Leotychidês having been obliged to retire without success, the Æginetans resolved to adopt measures of retaliation for themselves: they waited for the period of a solemn festival celebrated every fifth year at Sunium, on which occasion a ship peculiarly equipped and carrying some of the leading Athenians as Theôrs, or sacred envoys, sailed thither from Athens. This ship they found means to capture, and carried all on board prisoners to Ægina. Whether an exchange took place, or whether the prisoners and hostages on both sides were put to death, we do not know; but the consequence of their proceeding was an active and decided war between Athens and Ægina,[77] beginning seemingly about 488 or 487 B. C., and lasting until 481 B. C., the year preceding the invasion of Xerxes. [77] Herodot. vi, 87, 88.
