Seleucus in Harpers Dictionary of Classical Antiquities (1898)

Surnamed Ceraunus (226-223), eldest son and successor of Seleucus II. The surname of Ceraunus ("Thunderbolt") was given him by the soldiery, apparently in derision, as he appears to have been feeble both in mind and body. He was assassinated by two of his officers, after a reign of only three years, and was succeeded by his brother, Antiochus the Great.
