3. This is the general description [of Syria].[545]
In describing it in detail, we say that Commagene is rather a small district. It contains a strong city, Samosata, in which was the seat of the kings. At present it is a (Roman) province. A very fertile but small territory lies around it. Here is now the Zeugma, or bridge, of the Euphrates, and near it is situated Seleuceia, a fortress of Mesopotamia, assigned by Pompey to the Commageneans. Here Tigranes confined in prison for some time and put to death Selene, surnamed Cleopatra, after she was dispossessed of Syria.[546]
4. Seleucis is the best of the above-mentioned portions of Syria. It is called and is a Tetrapolis, and derives its name from the four distinguished cities which it contains; for there are more than four cities, but the four largest are Antioch Epidaphne,[547] Seleuceia in Pieria,[548] Apameia,[549] and Laodiceia.[550] They were called Sisters from the concord which existed between them. They were founded by Seleucus Nicator. The largest bore the name of his father, and the strongest his own. Of the others, Apameia had its name from his wife Apama, and Laodiceia from his mother.
In conformity with its character of Tetrapolis, Seleucis, according to Poseidonius, was divided into four satrapies; Cœle-Syria into the same number, but [Commagene, like] Mesopotamia, consisted of one.[551]
Antioch also is a Tetrapolis, consisting (as the name implies) of four portions, each of which has its own, and all of them a common wall.[552]
[Seleucus] Nicator founded the first of these portions, transferring thither settlers from Antigonia, which a short time before Antigonus, son of Philip, had built near it. The second was built by the general body of settlers; the third by Seleucus, the son of Callinicus; the fourth by Antiochus, the son of Epiphanes.
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.
