Seleucus (son of Ablabius)

Seleucus also known as Flavius Seleucus and Count Seleucus (Greek: Σέλευκος; fl. 4th century) was a wealthy Greek rhetor who was a close friend of Libanius and the Roman emperor Julian the Apostate.

Seleucus was a Greek nobleman who was the son of the wealthy Cretan Flavius Ablabius, by an unnamed woman. His family was connected to the ruling Constantinian dynasty of the Roman Empire as his father served Constantine I. Ablabius was one of the most important senators of Constantinople; who held the praetorian prefecture of the East from 329 to 337/338 and served as consul in 331, who was active in public posts in both East and West. Seleucus had at least one known sibling a sister called Olympias, who was once engaged to Constantine I’s son, the Roman emperor Constans who later married the Roman client king of Arsacid Armenia Arsaces II (Arshak II). Seleucus was born and raised either in Constantinople or Antioch, as his father during his political career was based in Antioch. His date of birth is unknown and little is known on his early life.

Seleucus knew Julian since his student days as his friendship with the nephew of Constantine I and the Rhetor, historian Libanius went back to the early 350s. Seleucus is recorded being with Julian in Bithynia in c.353 and in 356, Libanius praises Seleucus of his eloquence in his Rhetoric. Although a Christian by birth, Seleucus became a zealous pagan of the ancient Greek religion who was a learned person.
