As you ascend the hill on the road you pass, on your immediate right, four more mounds or hillocks. The last, or sixth mound, is at the top of the hill, and is a prominent object when viewed from the hot springs. Shortly after passing it the road begins to descend again; and about half a mile farther on you arrive at what was the east gate of the pass. Here the passage was narrow and short. It was formed by a somewhat lofty projecting ridge of the mountain slope, round the end of which the road passed. The five-yard contour makes a sudden bend inwards at this point. Herodotus tells us that, like the western gate, it afforded passage to but one waggon, and that it was near Alpenos (vii. 176). At the end of the same chapter he speaks of Alpenos as being “very near the road,” and as being the place from which the Greeks reckoned to supply their commissariat. #THE EAST GATE AND WALL.# ◆Site of Alpenos.◆ I think that the site of Alpenos is to be identified with the remains of a walled acropolis on a hill which stands out into the plain from the ὑπωρέη or lower slope of the mountain, about half a mile beyond the east gate. Between it and the east gate there must have been a bay of the sea, or harbour, to which, no doubt, the Greek provision ships went. Leake places Alpenos quite close to the middle gate (_vide_ his map), but that is quite inconsistent with H. vii. 176. The incomprehensibility of the eastern part of his map of Thermopylæ makes one suspect that either he had never visited the east end of the pass, or, if he had, had done so very hurriedly.
