Clemens Alexandrinus (Strom. 1:305) and Sozomen (1:12) mention Philo ὁ Πεθαγόρειος . It is probable from their language that they both mean by the person so designated PHILO JUDEUS. Jonsius (ibid. 3, c. 4, page 17) is strongly of opinion that Philo the elder and this Philo mentioned by Clemens are the same. Fabricius, who once held this opinion, was led to change his views (Bibl. 1:862), and tacitly assumes (4:738) that Sozomen indicates Philo Judaeus by this epithet.
