Anecdotes
After Alexander's death, Seleucus began modestly: he had received only a distant satrapy, Babylonia. Driven out by his rival Antigonus the One-Eyed, he fled to Egypt, then returned to retake Babylon in 312 BC — a return so decisive that the Seleucids made it the starting point of their calendar, the “Seleucid era.”
Around 305 BC, Seleucus carried the war all the way to the gates of India, facing the emperor Chandragupta Maurya. Rather than exhaust himself, he concluded a treaty: he ceded the eastern provinces and received in exchange 500 war elephants. These beasts made the difference at the Battle of Ipsus.
At Ipsus in 301 BC, his 500 elephants formed a living wall that cut off the enemy cavalry and sealed Antigonus's defeat. This victory made Seleucus the master of an immense empire, stretching from Asia Minor to the borders of India.
Seleucus was given the surname “Nicator,” meaning “the Victor.” Yet his final conquest proved fatal: in 281 BC, master of nearly all of Alexander's empire, he was assassinated in Europe by Ptolemy Keraunos, the son of his former ally, whom he had nonetheless welcomed at his court.
For political reasons, Seleucus gave up his own wife Stratonice to his son Antiochus. According to a famous story handed down by the ancients, the young prince was secretly dying of love for his stepmother, and a perceptive physician guessed the ailment by noticing his pulse racing at the sight of the young woman.
