ガイウス・カエサル
According to Josephus, Philo was largely inspired by Aristobulus of Alexandria and the Alexandrian school. The only event in Philo's life that can be decisively dated is his participation in the embassy to Rome in 40 CE; whereby he represented the Alexandrian Jews in a delegation to the Roman Emperor Gaius Caesar Augustus Germanicus (Caligula) following civil strife between the Alexandrian Jewish and Greek communities.
