Seleucus, the son of Theos and Laodice, surnamed
Callinicus (the Triumphant), succeeded Theos as king of
Syria. After Seleucus his two sons, Seleucus and Antiochus,
succeeded in the order of their age. As Seleucus was sickly and poor and unable to command the obedience of the army, he was poisoned by a court conspiracy in the
second year of his reign. His brother was Antiochus the
Great, who went to war with the Romans, of whom I have
written above. He reigned thirty-seven years. I have
already spoken of his two sons, Seleucus and Antiochus, both of whom ascended the throne. The former reigned twelve years, but feebly and without success by reason of his father's misfortune. Antiochus (Epiphanes) reigned not quite twelve years, in the course of which he captured Artaxias the Armenian and made an expedition into Egypt
against Ptolemy VI., who had been left an orphan with one
brother. While he was encamped near Alexandria, Popilius came to him as Roman ambassador, bringing an order in writing that he should not attack the Ptolemies. When he had read it he replied that he would think about it. Popilius drew a circle around him with a stick and
said, "Think about it here." He was terrified and withdrew
from the country, and robbed the temple of Venus Elymais; then died of a wasting disease, leaving a son nine years of age, the Antiochus Eupator already mentioned.
