Jewish sources on Emperors, polytheistic cult and the meaning of Empire are fraught with interpretive difficulties. In Caligula's reign, Jews resisted the placing of Caligula's statue in their Temple, and pleaded that their offerings and prayers to Yahweh on his behalf amounted to compliance with his request for worship. According to Philo, Caligula was unimpressed because the offering was not made directly to him (whether to his "genius" or his "numen" is never made clear) but the statue was never installed. Philo does not challenge the Imperial cult itself: he commends the god-like honours given Augustus as "the first and the greatest and the common benefactor" but Caligula shames the Imperial tradition by acting "like an Egyptian". However, Philo is clearly pro-Roman: a major feature of the First Jewish Revolt (AD 66) was the ending of Jewish sacrifices to Rome and the Emperor and the defacement of imperial images.
