Abstract
Herennius Philo of Byblos is the subject of a notice in the Suda, which states that he was a grammarian born in Nero's time who lived to such an advanced age that he was still composing works in the reign of Hadrian. The titles listed include: On the Acquisition and Choice of Books; On Cities and their Eminent Citizens; and On the Reign of Hadrian . His name, like that of Flavius Josephus, could imply the patronage of a Roman family; we may suppose that, like Porphyry and Maximus of Tyre, he was a Phoenicean by origin who had adopted the tongue and culture of the Greeks
