To the south of the town were the fortress and camp of the Greek mercenaries, who were probably settled there by Psammetikhos. The camp was surrounded by a wall, and within it stood the Hellênion, the common altar of the Ionians from Khios, Teos, Phokæa and Klazomenæ, of the Dorians from Rhodes, Knidos, Halikarnassos and Phasêlis, and of the Æolians of Mytilênê. The great enclosure still remains, as well as the lower chambers of the fort, and Mr. Petrie found that in the time of Ptolemy Philadelphus, when it was no longer needed for purposes of defence, it was provided with a stately entrance, to which an avenue of ruins led from the west. The traders and settlers built their houses north of the camp. Here too the Greek sailors and merchants, who had taken no part in the erection of the great altar, and who perhaps had no relations among the soldiers of the fort, built special temples for themselves. If we walk across the level ground which separates the fort from the old city, the first heap of rubbish we come to marks the site of the temple and sacred enclosure of Castor and Pollux. A little to the north was the still larger temple and _temenos_ or sacred enclosure of Apollo, and adjoining it, still on the north side, was the temple of Hêrê, whose _temenos_ was the largest of all. The temple of Apollo had been erected by the Milesians, and that it was the oldest in the city may be gathered from the archaic character of the inscriptions on the potsherds discovered in the trench into which the broken vases of the temple were thrown. The Samians were the builders of the temple of Hêrê, and Herodotos tells us that there was another dedicated to Zeus by the Æginetans. The ruins of this, however, have not yet been found, but far away towards the northern end of the ruin a small temple and _temenos_ of Aphroditê have been brought to light. Here Rhodôpis worshipped, who had been freed from slavery by the brother of Sappho, and whose charms were still celebrated at Naukratis in the days of Herodotos. Among the potsherds disinterred from the rubbish-trench of the temple of Apollo were portions of a large and beautiful bowl dedicated to “Phanês, the son of Glaukos.” Mr. Gardner is probably right in believing that this is the very Phanês who deserted to Kambyses, and, according to the Greek story, instructed him how to march across the desert into Egypt. It may be that Herodotos saw the bowl when it was still intact, and that the story of the deserter was told him over it; in any case, it was doubtless at Naukratis, and possibly from the priests of Apollo, that he heard it.
