Seleucus in Harpers Dictionary of Classical Antiquities (1898)
Surnamed Philopātor (187-175), was the son and successor of Antiochus the Great. The defeat of his father by the Romans, and the ignominious peace which followed it, had greatly diminished the power of the Syrian monarchy, and the reign of Seleucus was, in consequence, feeble and inglorious, and was marked by no striking events. He was assassinated in 175 by one of his own ministers. He left two children: Demetrius, who subsequently ascended the throne; and Laodicé, married to Perseus, king of Macedonia.
