The Jews then, having had leave given them by the prefect, sent an embassy to Rome, at the head of which was Philo, the platonic philosopher, who was to lay their grievances before the emperor, and to beg for redress. The Greeks also at the same time sent their embassy, at the head of which was the learned grammarian Apion, who was to accuse the Jews of not worshipping the statue of the emperor, and to argue that they had no right to the same privileges of citizenship with those who boasted of their Macedonian blood. But, as the Jews did not deny the charge that was brought against them, Caligula would hear nothing that they had to say; and Philo withdrew with the remark, "Though the emperor is against us, God will be our friend." We learn the sad tale of the Jews' suffering under Caligula from the pages of their own historian only. But though Philo may have felt and written as one of the sufferers, his truth is undoubted. He was a man of unblemished character, and the writer of greatest learning and of the greatest note at that time in Alexandria; being also of a great age, he well deserved the honour of being sent on the embassy to Caligula. He was in religion a Jew, in his philosophy a platonist, and by birth an Egyptian: and in his numerous writings we may trace the three sources from which he drew his opinions. He is always devotional and in earnest, full of pure and lofty thoughts, and often eloquent. His fondness for the mystical properties of numbers, and for finding an allegory or secondary meaning in the plainest narrative, seems borrowed from the Egyptians. According to the Eastern proverb every word in a wise book has seventy-two meanings; and this mode of interpretation was called into use by the necessity which the Jews felt of making the Old Testament speak a meaning more agreeable to their modern views of religion. In Philo's speculative theology he seems to have borrowed less from Moses than from the abstractions of Plato, whose shadowy hints he has embodied in a more solid form. He was the first Jewish writer that applied to the Deity the mystical notion of the Egyptians, that everything perfect was of three parts. Philo's writings are valuable as showing the steps by which the philosophy of Greece may be traced from the writings of Plato to those of Justin Martyr and Clemens Alexandrinus. They give us the earliest example of how the mystical interpretation of the Scriptures was formed into a system, by which every text was made to unfold some important philosophic or religious truth to the learned student, at the same time that to the unlearned reader it conveyed only the simple historic fact.
