Nothing that depended upon the stars was more important than decisions in time of war.The same Bonatto procured for the great Ghibelline leader Guido da Montefeltro a series of victories, by telling him the propitious hour for marching.When Montefeltro was no longer accompanied by him he lost the courage to maintain his despotism, and entered a Minorite monastery, where he lived as a monk for many years till his death.In the war with Pisa in 1362, the Florentines commissioned their astrologer to fix the hour for the march, and almost came too late through suddenly receiving orders to take a circuitous route through the city.On former occasions they had marched out by the Via di Borgo Santi Apostoli, and the campaign had been unsuccessful.It was clear that there was some bad omen connected with the exit through this street against Pisa, and consequently the army was now led out by the Porta Rossa.But as the tents stretched out there to dry had not been taken away, the flags--another bad omen--had to be lowered.The influence of astrology in war was confirmed by the fact that nearly all the Condottieri believed in it.Jacopo Caldora was cheerful in the most serious illness, knowing that he was fated to fall in battle, which in fact happened.Bartolommeo Alviano was convinced that his wounds in the head were as much a gift of the stars as his military command.Niccolo Orsini-Pitigliano asked the physicist and astrologer Alessandro Benedetto to fix a favourable hour for the conclusion of his bargain with Venice.When the Florentines on June 1, 1498, solemnly invested their new Condottiere Paolo Vitelli with his office, the Marshal's staff which they handed him was, at his own wish, decorated with pictures of the constellations.
Sometimes it is not easy to make out whether }n important political events the stars were questioned beforehand, or whether the astrologers were simply impelled afterwards by curiosity to find out the constellation which decided the result.When Giangaleazzo Visconti by a master-stroke of policy took prisoner his uncle Bernabo, with the latter's family (1385), we are told by a contemporary that Jupiter, Saturn and Mars stood in the house of the Twins, but we cannot say if the deed was resolved on in consequence.It is also probable that the advice of the astrologers was often determined by political calculation not less than by the course of the planets.
All Europe, through the latter part of the Middle Ages, had allowed itself to be terrified by predictions of plagues, wars, floods, and earthquakes, and in this respect Italy was by no means behind other countries.The unlucky year 1494, which for ever opened the gates of Italy to the stranger, was undeniably ushered in by many prophecies of misfortune--only we cannot say whether such prophecies were not ready for each and every year.
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.
So much more worthy then of recognition is the warfare which the clear Italian spirit waged against this army of delusions.Notwithstanding the great monumental glorification of astrology, as in the frescoes in the Salone at Padua, and those in Borso's summer palace (Schifanoia) at Ferrara, notwithstanding the shameless praises of even such a man as the elder Beroaldus, there was no want of thoughtful and independent minds to protest against it.Here, too, the way had been prepared by antiquity, but it was their own common sense and observation which taught them what to say.Petrarch's attitude towards the astrologers, whom he knew by personal intercourse, is one of bitter contempt; and no one saw through their system of lies more clearly than he.The novels, from the time when they first began to appear from the time of the 'Cento novelle antiche,' are almost always hostile to the astrologers.
The Florentine chroniclers bravely keep themselves free from the delusions which, as part of historical tradition, they are compelled to record.Giovanni Villani says more than once, 'No constellation can subjugate either the free will of man, or the counsels of God.' Matteo Villani declares astrology to be a vice which the Florentines had inherited, along with other superstitions, from their pagan ancestors, the Romans.The question, however, did not remain one for mere literary discussion, but the parties for and against disputed publicly.After the terrible floods of 1333, and again in 1345, astrologers and theologians discussed with great minuteness the influence of the stars, the will of God, and the justice of his punishments.These struggles never ceased throughout the whole time of the Renaissance, and we may conclude that the protestors were ill earnest, since it was easier for them to recommend themselves to the great by defending, than by opposing astrology.
