This article studies the inscription IG IV2 1.687 (FGrH 95), the only evidence for the historian Philip of Pergamon. The subjects considered include the text itself, the appearance of the stone and the layout in imitation of papyrus, the date as evidenced by the lettering, the use of the Ionic dialect and the references to ‘suffering and continuous mutual slaughter’. Finally, it is proposed that Philip may be ‘the historian Philip’ mentioned in a dialogue of Plutarch.
