This mode of thought was extended with thorough consistency into regions where we should hardly expect to meet with it. If the whole outward and spiritual life of the individual is determined by the facts of his birth, the same law also governs groups of individuals and historical products - that is to say, nations and religions; and as the constellation of these things changes, so do the things themselves. The idea that each religion has its day, first came into Italian culture in connection with these astrological beliefs. The conjunction of Jupiter with Saturn brought forth, we are told, the faith of Israel; that of Jupiter and Mars, the Chaldean; with the Sun, the Egyptian; with Venus, the Mohammedan; with Mercury, the Christian; and the conjunction of Jupiter with the Moon will one day bring forth the religion of Antichrist. Cecco d'Ascoli had already blasphemously calculated the nativity of Christ, and deduced from it his death upon the Cross. For this he was burnt at the stake in 1327, at Florence. Doctrines of this sort ended by simply darkening men's whole perceptions of spiritual things.
