5. Antioch is the metropolis of Syria. A palace was constructed there for the princes of the country. It is not much inferior in riches and magnitude to Seleuceia on the Tigris and Alexandreia in Egypt. [Seleucus] Nicator settled here the descendants of Triptolemus, whom we have mentioned a little before.[553] On this account the people of Antioch regard him as a hero, and celebrate a festival to his honour on Mount Casius[554] near Seleuceia. They say that when he was sent by the Argives in search of Io, who first disappeared at Tyre, he wandered through Cilicia; that some of his Argive companions separated from him and founded Tarsus; that the rest attended him along the sea-coast, and, relinquishing their search, settled with him on the banks of the Orontes;[555] that Gordys the son of Triptolemus, with some of those who had accompanied his father, founded a colony in Gordyæa, and that the descendants of the rest became settlers among the inhabitants of Antioch. 6. Daphne,[556] a town of moderate size, is situated above Antioch at the distance of 40 stadia. Here is a large forest, with a thick covert of shade and springs of water flowing through it. In the midst of the forest is a sacred grove, which is a sanctuary, and a temple of Apollo and Diana. It is the custom for the inhabitants of Antioch and the neighbouring people to assemble here to celebrate public festivals. The forest is 80 stadia in circumference. 7. The river Orontes flows near the city. Its source is in Cœle-Syria. Having taken its course under-ground, it reäppears, traverses the territory of Apameia to Antioch, approaching the latter city, and then descends to the sea at Seleuceia. The name of the river was formerly Typhon, but was changed to Orontes, from the name of the person who constructed the bridge over it. According to the fable, it was somewhere here that Typhon was struck with lightning, and here also was the scene of the fable of the Arimi, whom we have before mentioned.[557] Typhon was a serpent, it is said, and being struck by lightning, endeavoured to make its escape, and sought refuge in the ground; it deeply furrowed the earth, and (as it moved along) formed the bed of the river; having descended under-ground, it caused a spring to break out, and from Typhon the river had its name. On the west the sea, into which the Orontes discharges itself, is situated below Antioch in Seleuceia, which is distant from the mouth of the river 40, and from Antioch 120 stadia. The ascent by the river to Antioch is performed in one day. To the east of Antioch are the Euphrates, Bambyce,[558] Berœa,[559] and Heracleia, small towns formerly under the government of Dionysius, the son of Heracleon. Heracleia is distant 20 stadia from the temple of Diana Cyrrhestis.
