[1] The MSS. here give the words, "in the ephorate of Pantacles and the archonship of Antigenes, two-and-twenty years from the beginning of the war," but the twenty-second year of the war = B.C. 410; Antigenes archon, B.C. 407 = Ol. 93, 2; the passage must be regarded as a note mis-inserted by some editor or copyist (vide supra, I. 11.)
[2] I.e. sacred place or temple of Heracles.
[3] Twenty talents = 4800 pounds; or, more exactly, 4875 pounds.
This done, Pharnabazus left Chalcedon at once, with injunctions that those who were going up to the king as ambassadors should meet him at Cyzicus. The representatives of Athens were Dorotheus, Philodices, Theogenes, Euryptolemus, and Mantitheus; with them were two Argives, Cleostratus and Pyrrholochus. An embassy of the Lacedaemonians was also about to make the journey. This consisted of Pasippidas and his fellows, with whom were Hermocrates, now an exile from Syracuse, and his brother Proxenus. So Pharnabazus put himself at their head. Meanwhile the Athenians prosecuted the siege of Byzantium; lines of circumvallation were drawn; and they diversified the blockade by sharpshooting at long range and occasional assaults upon the walls. Inside the city lay Clearchus, the Lacedaemonian governor, and a body of Perioci with a small detachment of Neodamodes.[4] There was also a body of Megarians under their general Helixus, a Megarian, and another body of Boeotians, with their general Coeratadas. The Athenians, finding presently that they could effect nothing by force, worked upon some of the inhabitants to betray the place. Clearchus, meanwhile, never dreaming that any one would be capable of such an act, had crossed over to the opposite coast to visit Pharnabazus; he had left everything in perfect order, entrusting the government of the city to Coeratadas and Helixus. His mission was to obtain pay for the soldiers from the Persian satrap, and to collect vessels from various quarters. Some were already in the Hellespont, where they had been left as guardships by Pasippidas, or else at Antandrus. Others formed the fleet which Agesandridas, who had formerly served as a marine[5] under Mindarus, now commanded on the Thracian coast. Others Clearchus purposed to have built, and with the whole united squadron to so injure the allies of the Athenians as to draw off the besieging army from Byzantium. But no sooner was he fairly gone than those who were minded to betray the city set to work. Their names were Cydon, Ariston, Anaxicrates, Lycurgus, and Anaxilaus. The last-named was afterwards impeached for treachery in Lacedaemon on the capital charge, and acquitted on the plea that, to begin with, he was not a Lacedaemonian, but a Byzantine, and, so far from having betrayed the city, he had saved it, when he saw women and children perishing of starvation; for Clearchus had given away all the corn in the city to the Lacedaemonian soldiers. It was for these reasons, as Anaxilaus himself admitted, he had introduced the enemy, and not for the sake of money, nor out of hatred to Lacedaemon.
[4] According to the constitution of Lacedaemon the whole government was in Dorian hands. The subject population was divided into (1) Helots, who were State serfs. The children of Helots were at times brought up by Spartans and called "Mothakes"; Helots who had received their liberty were called "Neodamodes" ({neodamodeis}). After the conquest of Messenia this class was very numerous. (2) Perioeci. These were the ancient Achaean inhabitants, living in towns and villages, and managing their own affairs, paying tribute, and serving in the army as heavy-armed soldiers. In 458 B.C. they were said to number thirty thousand. The Spartans themselves were divided, like all Dorians, into three tribes, Hylleis, Dymanes, and Pamphyli, each of which tribes was divided into ten "obes," which were again divided into {oikoi} or families possessed of landed properties. In 458 B.C. there were said to be nine thousand such families; but in course of time, through alienation of lands, deaths in war, and other causes, their numbers were much diminished; and in many cases there was a loss of status, so that in the time of Agis III., B.C. 244, we hear of two orders of Spartans, the {omoioi} and the {upomeiones} (inferiors); seven hundred Spartans (families) proper and one hundred landed proprietors. See Mullers "Dorians," vol. ii. bk. iii. ch. x. S. 3 (Eng. trans.); Arist. "Pol." ii. 9, 15; Plut. ("Agis").
[5] The greek word is {epibates}, which some think was the title of an inferior naval officer in the Spartan service, but there is no proof of this. Cf. Thuc. viii. 61, and Prof. Jowett's note; also Grote, "Hist. of Greece," viii. 27 (2d ed.)
As soon as everything was ready, these people opened the gates leading to the Thracian Square, as it is called, and admitted the Athenian troops with Alcibiades at their head. Helixus and Coeratadas, in complete ignorance of the plot, hastened to the Agora with the whole of the garrison, ready to confront the danger; but finding the enemy in occupation, they had nothing for it but to give themselves up. They were sent off as prisoners to Athens, where Coeratadas, in the midst of the crowd and confusion of debarkation at Piraeus, gave his guards the slip, and made his way in safety to Decelia.
