It is fairly certain, moreover, that Philo sojourned some time in Jerusalem. He was there probably during the reign of Agrippa (_c._ 30 C.E.), who was an intimate friend of his family, and had found a refuge at Alexandria when an exile from Palestine and Rome. In the first book on the Mosaic laws[53] Philo speaks with enthusiasm of the great temple, to which "vast assemblies of men from a countless variety of cities, some by land, some by sea, from East, West, North, and South, come at every festival as if to some common refuge and harbor from the troubles of this harassed and anxious life, seeking to find there tranquillity and gain a new hope in life by its joyous festivities." These gatherings, at which, according to Josephus,[54] over two million people assembled, must, indeed, have been a striking symbol of the unity of the Jewish race, which was at once national and international; magnificent embassies from Babylon and Persia, from Egypt and Cyrene, from Rome and Greece, even from distant Spain and Gaul, went in procession together through the gate of Xistus up the temple-mount, which was crowned by the golden sanctuary, shining in the full Eastern sun like a sea of light above the town. Philo describes in detail the form of the edifice that moved the admiration of all who beheld it, and for the Jew, moreover, was invested with the most cherished associations. Its outer courts consisted of double porticoes of marble columns burnished with gold, then came the inner courts of simple columns, and "within these stood the temple itself, beautiful beyond all possible description, as one may tell even from what is seen in the outer court; for the innermost sanctuary is invisible to every being except the high priest." The majesty of the ceremonial within equalled the splendor without. The high priest, in the words of Ben Sira (xlv), "beautified with comely ornament and girded about with a robe of glory," seemed a high priest fit for the whole world. Upon his head the mitre with a crown of gold engraved with holiness, upon his breast the mystic Urim and Thummim and the ephod with its twelve brilliant jewels, upon his tunic golden pomegranates and silver bells, which for the mystic ear pealed the harmony of the world as he moved. Little wonder that, inspired by the striking gathering and the solemn ritual, Philo regarded the temple as the shrine of the universe,[55] and thought the day was near when all nations should go up there together, to do worship to the One God.
