Hadrian had requested the Alexandrians to postpone the theatrical displays and processions that they had prepared for him, as his observations as to the course of destiny during the coming year were not yet complete. Every evening he ascended the lofty observatory of the Serapeum and gazed from thence at the stars. His labors ended on the tenth of January; on the eleventh the festivities began. They lasted through many days, and by the desire of the praetor the pretty daughter of Apollodorus the Jew was chosen to represent Roxana. Everything that the Alexandrians had prepared to do honor to their sovereign was magnificent and costly. So many ships had never before been engaged in any Naumachia as were destroyed here in the sham sea-fight, no greater number of wild beasts had ever been seen together on any occasion even in the Roman Circus; and how bloody were the fights of the gladiators, in which black and white combatants afforded a varied excitement for both heart and senses. In the processions, the different elements which were supplied by the great central metropolis of Egyptian, Greek and Oriental culture afforded such a variety of food for the eye that, in spite of their interminable length, the effect was less fatiguing than the Romans had feared. The performances of the tragedies and comedies were equally rich in startling effects; conflagrations and floods were introduced and gave the Alexandrian actors the opportunity of displaying their talents with such brilliant success that Hadrian and his companions were forced to acknowledge that even in Rome and Athens they had never witnessed any representations equally perfect. A piece by the Jewish author Ezekiel who, under the Ptolemies, wrote dramas in the Greek language of which the subject was taken from the history of his own people, particularly claimed the Emperor's attention.
