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).

3 First coins of Alexander II from Antioch mint are dated SE 184 (September 129 - October 128), see, e.g., SNG Spaer, 2375 ff. The revolt in Antioch is explicitly mentioned by Justin, Epitome of the Philippic History of Pompeius Trogus, 39.1:

After Antiochus (Antiochos VII) and his army were cut off in Persia, his brother Demetrius (Demetrios II), being delivered from confinement among the Parthians, and restored to his throne, resolved, while all Syria was mourning for the loss of the army, to make war upon Egypt, (just as if his and his brother’s wars with the Parthians, in which one was taken prisoner and the other killed, had had a fortunate termination), Cleopatra his mother-in-law (Kleopatra II, queen of Egypt and mother of Kleopatra Thea, Demetrios II’s wife) promising him the kingdom of Egypt, as a recompence for the assistance that he should afford her against her brother (Ptolemy VIII). But, as is often the case, while he was grasping at what belonged to others, he lost his own by a rebellion in Syria; for the people of Antioch, in the first place, under the leadership of Trypho (either an otherwise unknown man or a confusion with the previous usurper Diodotos Tryphon), and from detestation of the pride of their king (which, from his intercourse with the unfeeling Parthians, had become intolerable), and afterwards the Apamenians and other people, following their example, revolted from Demetrius in his absence. Ptolemy (Ptolemy VIII), king of Egypt, too, who was threatened with a war by him, having learned that his sister Cleopatra (Kleopatra II) had put much of the wealth of Egypt on ship-board, and fled into Syria to her daughter and son-in-law Demetrius, sent an Egyptian youth, the son of a merchant named Protarchus, to claim the throne of Syria by force of arms, having forged a story, that he had been admitted into the family of King Antiochus (Antiochos VII) by adoption, and the Syrians, at the same time, refusing no man for their king, if they might but be freed from the insolence of Demetrius. The name of Alexander (Alexander II) was given to the youth, and great succours were sent him from Egypt.
