THE HISTORY [289]
the pathway, by which the Greeks who fell at Thermopylae were intercepted, they had no knowledge, until, on their arrival at Thermopylae, it was discovered to them by the Trachinians. This pass then it was determined that they should guard, in order to prevent the barbarians from penetrating into Greece through it; and at the same time it was resolved that the fleet should proceed to Artemisium, in the region of Histiaeotis, for, as those places are near to one another, it would be easy for the fleet and army to hold communication. The two places may be thus described. Artemisium is where the sea of Thrace contracts into a narrow channel, running between the isle of Sciathus and the mainland of Magnesia. When this narrow strait is passed you come to the line of coast called Artemisium; which is a portion of Euboea, and contains a temple of Artemis (Diana). As for the entrance into Greece by Trachis, it is, at its narrowest point, about fifty feet wide. This however is not the place where the passage is most contracted; for it is still narrower a little above and a little below Thermopylae. At Alpini, which is lower down than that place, it is only wide enough for a single carriage; and up above, at the river Phoenix, near the town called Anthela, it is the same. West of Thermopylae rises a lofty and precipitous hill, impossible to climb, which runs up into the chain of Oeta; while to the east the road is shut in by the sea and by marshes. In this place are the warm springs, which the natives call "The Cauldrons"; and above them stands an altar sacred to Hercules. A wall had once been carried across the opening; and in this there had of old times been a gateway. These works were made by the Phocians, through fear of the Thessalians, at the time when the latter came from Thesprotia to establish themselves in the land of Aeolis, which they still occupy. As the Thessalians strove to reduce Phocis, the Phocians raised the wall to protect themselves, and likewise turned the hot springs upon the pass, that so the ground might be broken up by watercourses, using thus all possible means to hinder the Thessalians from invading their country. The old wall had been built in very remote times; and the greater part of it had gone to decay through age. Now however the Greeks resolved to repair its breaches, and here make their stand against the barbarian. At this point there is a village very nigh the road, Alpeni by name, from which the Greeks reckoned on getting corn for their troops. These places, therefore, seemed to the Greeks fit for their purpose. Weighing well all that was likely to happen, and considering that in this region the barbarians could make no use of their vast numbers, nor of their cavalry, they resolved to await here the invader of Greece. And when news reached them of the Persians being in Pieria, straightway they broke up from the Isthmus, and proceeded, some on foot to Thermopylae, others by sea to Artemisium. The Greeks now made all speed to reach the two stations; and about the same time- the Delphians, alarmed both for themselves and for their country, consulted the god, and received for answer a command to "pray to the winds, for the winds would do Greece good service." So when this answer was given them, forthwith the Delphians sent word of the prophecy to those Greeks who were zealous for freedom, and, cheering them thereby amid the fears which they entertained with respect to the barbarian, earned their everlasting gratitude. This done, they raised an altar to the winds at Thyia (where Thyia, the daughter of Cephissus, from whom the region takes its name, has a precinct), and worshipped them with sacrifices. And even to the present day the Delphians sacrifice to the winds, because of this oracle. The fleet of Xerxes now departed from Therma; and ten of the swiftest sailing ships ventured to stretch across direct for Sciathus, at which place there were upon the look-out three vessels belonging to the Greeks, one a ship of Troezen, another of Egina, and the third from Athens. These vessels no
