If, having forgotten what the lunar fundament is, you wish to investigate it: take the lunar cycle of any year whatsoever, and multiply it by eleven: add three to the sum. Divide whatever has been collected by thirty: if the remainder is beneath thirty, it exhibits the sought-after lunar fundament.
CONCERNING THE SIGNIFICATIONS OF THE STARS
From the third section of the Tetrabiblos of Aetius of Amida, chapter 164. Translated by Cornarius.B Since the stars in the heavens, rising according to the times ordained for them by God, and similarly setting, alter the air, so that it happens from this that winds also blow at one time differently than at another, I have deemed it necessary here to indicate the times in which the risings and settings of those that clearly alter the air occur. For the bodies of those in health, and much more so of those who are ill, are altered according to the state of the air.
In the month of Dystrus, which is March, the Horse rises in the morning on the nineteenth day. In the same month, on the twenty-third, is the vernal equinox; and there is the greatest disturbance of the air. In the month of Xanthicus, that is April, on the first day, the Pleiades appear at the beginning of the night. In the same month, on the nineteenth, the Pleiades are hidden in the evening. In the same month, on the twenty-first, the Pleiades rise with the rising of the sun; and the disturbance concerning the air is greatest. In the same month, on the twenty-seventh, Orion is hidden in the evening. In the month of Artemisius, which is May, on the first day, the Hyades rise with the rising of the sun. In the same month, on the fourth, Lyra rises in the evening, and the air is altered considerably. In the same month, on the sixth, the Goat rises in the morning, and the air is strongly altered for a day or two. In the month of May, on the seventh, the Pleiades appear in the morning, and the air begins to settle.
On the nineteenth of May, the Hyades appear in the morning, and the air is strongly altered the day before, or two days before. A On the twenty-fourth of the same month, the Goat is hidden in the evening, and the air is disturbed two days before.
On the second of June, the Eagle rises in the evening. On the sixth of the same month, Arcturus sets in the morning. On the ninth of the same month, the Dolphin rises in the evening. On the twenty-fifth of the same month, Orion begins to rise in the morning. These are the summer solstices; and the air is strongly altered three days before.
On the third of July, the whole of Orion rises. On the fourteenth, Procyon rises in the morning. On the nineteenth, the Dog-star rises in the morning; and there occurs a very great disturbance of the air, sometimes even two days before. On the twenty-fifth, the Eagle sets in the morning; and the air is moved for three days before. B
On the fifteenth of August, Lyra sets in the morning. On the nineteenth, the Dolphin sets in the morning; and this is the change from summer to cold weather. On the twenty-eighth, the Vindemiator rises in the morning, and the mast of the Ship sets: and this is the end of the forty days after the rising of the Dog-star.
On the seventh of September, the Goat rises in the evening. On the seventeenth, Arcturus rises, and it alters the air on the following day. On the nineteenth, Spica rises in the morning, and the air is altered two days before. On the twenty-fifth, the autumnal equinox occurs, and there is a great disturbance of the air three days before: wherefore C one must be careful not to open a vein, nor to purge, nor otherwise to move the body with violent movement from the fifteenth of September until the twenty-fourth of the same month.
On the sixth of October, the Crown rises in the morning, and there is a violent change of the air. On the seventh, the Kids rise in the evening. On the seventeenth, the Hyades rise in the evening, and a great disturbance of the air occurs. On the twenty-third, the Pleiades set at sunrise, and the greatest disturbance of the air occurs the day before.
On the sixth of November, the Pleiades set in the morning, and the air begins to settle. D On the eleventh, Lyra rises in the morning. On the twenty-first, the Hyades set in the morning, and a disturbance occurs in the air on the following day. On the twenty-seventh, Orion rises, and the Crown sets.
On the first of December, the Dog-star sets in the morning. It has been observed by many that if this day is stormy, the disturbance of the air generally persists for thirty-seven days. If, however, it is clear, it signifies that there will be serenity for as many days. On the tenth, the Kids set in the morning. On the eleventh, the Goat sets in the morning, and a disturbance of the air occurs the day after.
