Note 28:3 — INTRODUCTION.[vii:1]

Ptolemy Ceraunus was the eldest son of Ptolemy Soter; but, on account of his violent passions and moral obliquity, his father designated a younger son as his successor. Ceraunus then emigrated to Macedonia, became intimate with Seleucus, murdered him treacherously, and himself assumed the sovereignty; but in less than a year he was defeated by the Gauls who then first invaded that region, was taken prisoner, and was put to death with the utmost barbarity.
