Astrology, however, revealed the future not only of the universe, but also of man. According to a Chaldeo-Persian doctrine, accepted by the pagan mystics and previously pointed out by us,[40] a bitter necessity compelled the souls that dwell in great numbers on the celestial heights, to descend upon this earth and to animate certain bodies that are to hold them in captivity. In descending to the earth they travel through the spheres of the planets and receive some quality from each of these wandering stars, according to its positions. Contrariwise, when death releases them from their carnal prison, they return to their first habitation, providing they have led a pious life, and if as they pass through the doors of the superposed heavens they divest themselves of the passions and inclinations acquired during their first journey, { 178} to ascend finally, as pure essence to the radiant abode of the gods. There they live forever among the eternal stars, freed from the tyranny of destiny and even from the limitations of time.
This alliance of the theorems of astronomy with their old beliefs supplied the Chaldeans with answers to all the questions that men asked concerning the relation of heaven and earth, the nature of God, the existence of the world, and their own destiny. Astrology was really the first scientific theology. Hellenistic logic arranged the Oriental doctrines properly, combined them with the Stoic philosophy and built them up into a system of indisputable grandeur, an ideal reconstruction of the universe, the powerful assurance of which inspired Manilius to sublime language when he was not exhausted by his efforts to master an ill-adapted theme.[41] The vague and irrational notion of "sympathy" is transformed into a deep sense of the relationship between the human soul, an igneous substance, and the divine stars, and this feeling is strengthened by thought.[42] The contemplation of the sky has become a communion. During the splendor of night the mind of man became intoxicated with the light streaming from above; born on the wings of enthusiasm, he ascended into the sacred choir of the stars and took part in their harmonious movements. "He participates in their immortality, and, before his appointed hour, converses with the gods."[43] In spite of the subtle precision the Greeks always maintained in their speculations, the feeling that permeated astrology down to the end of paganism never belied its Oriental and religious origin. { 179}
