1 Antioch was founded about 300 BC by Seleukos I Nikator, the founder of the Seleukid Dynasty, and it became the principal capital of the Seleukid Empire. The city was named after a family name Antiochos, passed from his father to his son (Antiochos I Soter). There were a number of other cities by the same name and this Antioch was known as Antioch on the Orontes (i.e. the Orontes River, along which it was located).

2 The omphalos (“navel” in Greek) was a sacred stone at Delphi. It was supposed to mark the center of the earth. Similar stones were erected in several areas surrounding the Mediterranean Sea.

Pausanias, Description of Greece, 10.16.3: What is called the Omphalus by the Delphians is made of white marble, and is said by the Delphians to be the center of all the earth.

3 The city was founded in 312 BC by Seleukos I Nikator at the confluence of the Tigris River and a major canal from the Euphrates. Seleukeia on the Tigris was one of the great Hellenistic cities and a very important trading centre.

Appian, Syriake 58, tolds the following legend about how the city was established: ... They say, also, that when the Magians were ordered to indicate the propitious day and hour for beginning the foundations of Seleucia-on-the-Tigris they falsified as to the hour because they did not want to have such a stronghold built against themselves. While the king (Seleukos I Nikator) was waiting in his tent for the appointed hour, and the army, in readiness to begin the work, stood quietly till Seleucus should give the signal, suddenly, at the true hour of destiny, they seemed to hear a voice ordering them on. So they sprang to their work with such alacrity that the heralds who tried to stop them were not able to do so. When the work was brought to an end Seleucus, being troubled in his mind, again made inquiry of the Magians concerning his city, and they, having first secured a promise of impunity, replied, “That which is fated, o king, whether it be for better or worse, neither man nor city can change, for there is a fate for cities as well as for men. It pleases the gods that this city shall endure for ages, because it was begun on the hour on which it was begun. We feared lest it should be a stronghold against ourselves, and falsified the appointed time. Destiny is stronger than crafty Magians or an unsuspecting king. For that reason the deity announced the more propitious hour to the army. It is permitted you to know these things so surely that you need not suspect us of deception still, for you were presiding over the army yourself, as king, and you had yourself ordered them to wait; but the army, ever obedient to you in facing danger and toil, could not now be restrained, even when you gave them the order to stop, but sprang to their work, not a part of them merely, but all together, and their officers with them, thinking that the order had been given. In fact it had been given. That was the reason why not even you could hold them back. What can be stronger in human affairs than a king, unless it be a god, who overcame your intention and supplanted us in giving you directions about the city; for the god is in hostility to us and to all the people round about? What can our resources avail hereafter with a more powerful race settled along side of us? This city of yours has had a fortunate beginning, it will be great and enduring. We beg that you will confirm your pardon of our fault which we committed from fear of the loss of our own prosperity.” The king was pleased with what the Magians said and pardoned them. This is what I have heard about Seleucia.
