I beg the reader, interested in these sorts of comparisons, to reflect a moment upon the idea of Pythagoras. He will find here the veritable source of the astrological science of the ancients. Doubtless he is not ignorant of what an extended influence this science exercised already upon the face of the globe. The Egyptians, Chaldeans, Phœnicians, did not separate it from that which regulated the cult of the gods.[429] Their temples were but an abridged image of the Universe, and the tower which served as an observatory was raised at the side of the sacrificial altar. The Peruvians followed, in this respect, the same usages as the Greeks and Romans.[430] Everywhere the grand Pontiff united the science of genethlialogy or astrology with the priesthood, and concealed with care the principles of this science within the precincts of the sanctuary.[431] It was a Secret of State among the Etruscans and at Rome,[432] as it still is in China and Japan.[433] The Brahmans did not confide its elements except to those whom they deemed worthy to be initiated.[434] For one need only lay aside an instant the bandage of prejudice to see that an Universal science, linked throughout to what men recognize as the most holy, can not be the product of folly and stupidity, as has been reiterated a hundred times by a host of moralists. All antiquity is certainly neither foolish nor stupid, and the sciences it cultivated were supported by principles which, for us today, being wholly unknown, have none the less existed. Pythagoras, if we give attention here, revealed to us those of genethlialogy and of all the sciences of divination which relate thereunto.
