The astrological knowledge of the Egyptians appears to have been exercised chiefly in the casting of horoscopes. Certain gods presided over certain periods of time, while others were identified with the heavenly bodies, and all were supposed to have power over the events which occurred in the periods subject to their control. In the later papyri spheres or tables of nativity are found, by means of which the fate of a man could be calculated from such data as the hour of his birth and so forth. As among most Oriental peoples, astrological calendars, stating which days were auspicious or otherwise, were greatly in vogue, and these were to some extent founded on mythological events which had taken place on such and such a date, thus lending to it a certain significance for all time. Dreams Dreams were also greatly relied upon in the affairs of life. These were believed to be sent by the gods, and it is probable that the Egyptian who was exercised over his private affairs sought his repose in the hope of being vouchsafed a dream which would guide him in his conduct. Such a practice is in vogue amongst certain North American Indian tribes to-day. Savage man goes to sleep trusting that his totem will grant him a vision for the regulation of his future affairs. If the ancient Egyptian desired such illumination, he considered it wiser to sleep within a temple famous as the seat of an oracle. A class of professional interpreters existed whose business it was to make clear the enigmatic portions of dreams. It was thought that diseases might be cured by nostrums communicated by the gods during sleep. Mummy Magic
