The opposition of the luminaries preceding the aforementioned entry of the sun into Aries will be on the fourth day of March, after sunset, at nineteen hours and thirty minutes, which will be Tuesday, the hour of Jupiter, in the Roman horizon, with the second degree of Leo ascending. And because the ascendant of the mundane year is a common sign, therefore according to the opinions of the wise, the revolutions of all other quarters are not necessary, but this year will be bipartite, namely in the two equinoctial points. Wherefore I shall add the entry of the sun into the autumnal equinox, namely in the sign of Libra, which will be in the same year on the twelfth day of the month of September, after midday at twenty-two hours and forty minutes, which will be Saturday, the hour of Venus, in the Roman horizon, equalized, with the twenty-ninth degree of Scorpio almost ascending. The conjunction indeed preceding the aforementioned entry of the sun into Libra was in the aforementioned year on the twelfth of September, after sunset, at ten hours and almost five minutes, which will be Thursday, the hour of Mars, with the sixth degree of Virgo almost ascending. And it is to be noted that he who wishes to judge this year canonically must look not only at the entry of the sun into those two equinoctial points as has been said, and at the opposition and conjunction preceding those entries, and at the eclipse of the sun to happen in the present year, but one must remember some past constellations. And especially to remember the eclipse of the sun made in the past year, 1481, on the twenty-eighth of May, in the sixteenth degree of Gemini. And of the conjunction of Jupiter and Mars made in the month of August, on the thirteenth, in the twenty-first degree of Leo. Similarly, to remember the conjunction of the evils, Saturn and Mars, made on the seventeenth day of November, in the twenty-second degree of Libra incomplete, and this is because all the aforementioned constellations will sprout their effects more in this year. Indeed, I will distinguish the judgments of this monster in twenty-one chapters, all of which must be read from beginning to end so that they may be understood more perfectly.
Chapter one concerning the lord of the year.
It is necessary to establish the Sun in Italy as the principal lord of the year. I say that Mars is to be made the leader, Venus also the receiver of Mercury, the lord of the ascendant of the mundane year, and because of many testimonies, it acquires no small power for itself in the year and deserves to be the significator of kings.
Chapter two concerning two constellations.
I say that two principal constellations are expected this year. One, indeed, will be an eclipse of the Sun, and it will happen on Friday, the seventeenth of May, in the sixth degree of Gemini. It will begin for us at the twenty-third hour of the clock with almost forty-two minutes, with the third degree of Sagittarius ascending. The middle of it will be after sunset, at the zero hour with almost seventeen minutes, with the fourth degree of the same ascending sign. The end also of the eclipse itself will be at the first hour of the same night with almost thirty-two minutes, with the twenty-sixth degree of the same sign, namely Sagittarius ascending.
