(20) For the motion of the sun from solstice to solstice is completed in six months - in the course of which, at one time the leaves fall, and at another plants bud and seeds come to maturity. And they say that the embryo is perfected exactly in the sixth month, that is, in one hundred and eighty days in addition to the two and a half, as Polybus the physician relates in his book On the Eighth Month, and Aristotle the philosopher in his book On Nature. Hence the Pythagoreans, as I think, reckon six the perfect number, from the creation of the world, according to the prophet, and call it Meseuthys and Marriage, from its being the middle of the even numbers, that is, of ten and two. For it is manifestly at an equal distance from both.

(10) Each year the sun passes entirely around the zodiac and returns to the point from which it started--the vernal equinox--and each year it falls just a little short of making the complete circle of the heavens in the allotted period of time. As a result, it crosses the equator just a little behind the spot in the zodiacal sign where it crossed the previous year. Each sign of the zodiac consists of thirty degrees, and as the sun loses about one degree every seventy two years, it regresses through one entire constellation (or sign) in approximately 2,160 years, and through the entire zodiac in about [paragraph continues]

(6) For this reason the years will come upon them when they will disturb (the order), ' A lunar year consists of 354 days. Our author wages a polemic against the use of the moon for determining the seasons and feasts. But a lunar year was accepted by the Pharisees. and make an abominable (day) the day of testimony, and an unclean day a feast day, and they will con- found all the days, the holy with the unclean, and the unclean day with the holy; for they will go wrong as to the months and sabbaths and feasts and jubilees.

(6) For there will be those who will assuredly make observations of the moon — now (it) disturbeth the seasons and cometh in from year to year ten days too soon.*

(6) And twice in every year the day and night are equal, for on the original attack, when it (the sun) went forth from its first degree (khûrdak), the day and night were equal, it was the season of spring; when it arrives at the first degree of Kalakang (Cancer) the time of day is greatest, it is the beginning of summer; when it arrives at the sign (khûrdak) Tarâgûk (Libra) the day and night are equal, it is the beginning of autumn; when it arrives at the sign Vahîk (Capricorn) the night is a maximum, it is the beginning of winter; and when it arrives at Varak (Aries) the night and day have again become equal, as when it went forth from Varak.

(65) The SUN has its own royal place to itself, and does not go away from that place where it came to be at the first. Some suppose that it runneth round about the globe of the earth in a day and a night; and some of the astrologers also write so; and some have undertaken to measure how far its orb and circumference of its supposed motion is.

(3) Now the number 300 is, 3 by 100. Ten is allowed to be the perfect number. And 8 is the first cube, which is equality in all the dimensions - length, breadth; depth. "The days of men shall be," it is said, "120 (rk) years." And the sum is made up of the numbers from r to 15 added together. And the moon at 15 days is full.

(20) As the zodiacal band marks the pathway of the sun through the constellations, it results in the phenomena of the seasons. The ancient systems of measuring the year were based upon the equinoxes and the solstices. The year always began with the vernal equinox, celebrated March 21 with rejoicing to mark the moment when the sun crossed the equator northward up the zodiacal arc. The summer solstice was celebrated when the sun reached its most northerly position, and the day appointed was June 21. After that time the sun began to descend toward the equator, which it recrossed southbound at the autumnal equinox, September 21. The sun reached its most southerly position at the winter solstice, December 21.

(66) This opinion or supposition is not right, but the earth rolleth itself about; and runneth with the other planets, as in a wheel, round about the sun. The earth does not remain staying in one place, but in a year runneth round once about the sun, as the other planets next the sun, but Saturn and Jupiter, as also Mars, by reason of their great orb, circumference, and great height, cannot do it [in a year], because they stand so high above, and far distant from the SUN. Now it may be asked, What is the SUN, and what are the other PLANETS? Or how are they come to be?

(13) 25,920 years. (Authorities disagree concerning these figures.) This retrograde motion is called the precession of the equinoxes. This means that in the course of about 25,920 years, which constitute one Great Solar or Platonic Year, each one of the twelve constellations occupies a position at the vernal equinox for nearly 2,160 years, then gives place to the previous sign.

(28) The period of 2,160 years required for the regression of the sun through one of the zodiacal constellations is often termed an age. According to this system, the age secured its name from the sign through which the sun passes year after year as it crosses the equator at the vernal equinox. From this arrangement are derived the terms The Taurian Age, The Aryan Age, The Piscean Age, and The Aquarian Age. During these periods, or ages, religious worship takes the form of the appropriate celestial sign--that which the sun is said to assume as a personality in the same manner that a spirit assumes a body. These twelve signs are the jewels of his breastplate and his light shines forth from them, one after the other.

(6) To the Egyptians the sun was the symbol of immortality, for, while it died each night, it rose again with each ensuing dawn. Not only has the sun this diurnal activity, but it also has its annual pilgrimage, during which time it passes successively through the twelve celestial houses of the heavens, remaining in each for thirty days. Added to these it has a third path of travel, which is called the precession of the equinoxes, in which it retrogrades around the zodiac through the twelve signs at the rate of one degree every seventy-two years.

(4) The reappearance of the moon, and the creation of the month

(23) And the days will begin to grow many and increase amongst those children of men, Till their days draw nigh to one thousand years, And to a greater number of years than (before) was the number of the days.

(2) As this was six thousand years series of millennium reigns of Cancer, Leo, and Virgo had elapsed, because it was six thousand years when the millennium reign came to Libra, the adversary rushed in, and Gâyômard lived thirty years in tribulation. After the thirty years Mâshya and Mashyôî grew up; it was fifty years while they were not wife and husband, and they were ninety-three years together as wife and husband till the time when Hôshyang came. 4. Hôshyang was forty years, Takhmôrup thirty years, Yim till his glory departed six hundred and sixteen years and six months, and after that he was a hundred years in concealment. 5. Then the millennium reign came to Scorpio, and Dahâk ruled a thousand years. 6. After the millennium reign came to Sagittarius, Frêdûn reigned five hundred years; in the same five hundred years of Frêdûn were the twelve years of Aîrîk; Mânûskîhar was a hundred and twenty years, and in the same reign of Mânûskîhar, when he was in the mountain fastness (dûshkhvâr-gar), were the twelve years of Frâsîyâv; Zôb the Tûhmâspian was five years. 7. Kaî-Kabâd was fifteen years; Kaî-Kâûs, till he went to the sky, seventy-five years, and seventy-five years after that, altogether a hundred and fifty years; Kai-Khûsrôv sixty years; Kaî-Lôrâsp a hundred and twenty years; Kaî-Vistâsp, till the coming of the religion, thirty years, altogether a hundred and twenty years. 8. Vohûman son of Spend-dâd a hundred and twelve years; Hûmâî, who was daughter of Vohûman, thirty years; Dârâî son of Kîhar-i-âzâd, that is, of the daughter of Vohûman, twelve years; Dârâî son of Dârâî fourteen years; Alexander the Rûman fourteen years. 9. The Askânians bore the title in an uninterrupted (a-arûbâk) sovereignty two hundred and eighty-four years, Ardashîr son of Pâpak and the number of the Sâsânians four hundred and sixty years, and then it went to the Arabs.

(20) At the vernal equinox, the sun had grown to be a beautiful youth. His golden hair hung in ringlets on his shoulders and his light, as Schiller said, extended to all parts of infinity. At the summer solstice, the sun became a strong man, heavily bearded, who, in the prime of maturity, symbolized the fact that Nature at this period of the year is strongest and most fecund. At the autumnal equinox, the sun was pictured as an aged man, shuffling along with bended back and whitened locks into the oblivion of winter darkness. Thus, twelve months were assigned to the sun as the length of its life. During this period it circled the twelve signs of the zodiac in a magnificent triumphal march. When fall came, it entered, like Samson, into the house of Delilah (Virgo), where its rays were cut off and it lost its strength. In Masonry, the cruel winter months are symbolized by three murderers who sought to destroy the God of Light and Truth.

(2) It is always necessary first to count the day and afterwards the night, for first the day goes off, and then the night comes on. And from the season (gâs) of Mêdôk-shêm, which is the auspicious day Khûr of the month Tîr, to the season of Mêdîyârêm, which is the auspicious day Vâhrâm of the month Dîn—the shortest day—the night increases; and from the season of Mêdîyârêm to the season of Mêdôk-shêm the night decreases and the day increases. 4. The summer day is as much as two of the shortest winter days, and the winter night is as much as two of the shortest summer nights. 5. The summer day is twelve Hâsars, the night six Hâsars; the winter night is twelve Hâsars, the day six; a Hâsar being a measure of time and, in like manner, of land. 6. In the season of Hamêspamadâyêm, that is, the five supplementary days at the end of the month Spendarmad, the day and night are again equal. 7. As from the auspicious day Aûharmazd of the month Fravardîn to the auspicious day Anîrân of the month Mitrô is the summer of seven months, so from the auspicious day Aûharmazd of the month Âvân to the auspicious month Spendarmad, on to the end of the five supplementary days, is winter of five months. 8. The priest fulfils the regulation (vakar) about a corpse and other things, by this calculation as to summer and winter. 9. In those seven months of summer the periods (gâs) of the days and nights are five—since one celebrates the Rapîtvîn—namely, the period of daybreak is Hâvan, the period of midday is Rapîtvîn, the period of afternoon is Aûzêrîn, when the appearance of the stars has come into the sky until midnight is the period of Aîbisrûtêm, from midnight until the stars become imperceptible is the period of Aûshahîn. 10. In winter are four periods, for from daybreak till Aûshahîn is all Hâvan, and the rest as I have said; and the reason of it is this, that the appearance of winter is in the direction of the north, where the regions Vôrûbarst and Vôrûgarst are; the original dwelling of summer, too, is in the south, where the regions Fradadafsh and Vîdadafsh are; on the day Aûharmazd of the auspicious month Âvân the winter acquires strength and enters into the world, and the spirit of Rapîtvîn goes from above-ground to below-ground, where the spring (khânî) of waters is, and diffuses warmth and moisture in the water, and so many roots of trees do not wither with cold and drought. 11. And on the auspicious day Âtarô of the month Dîn the winter arrives, with much cold, at Aîrân-vêg; and until the end, in the auspicious month Spendarmad, winter advances through the whole world; on this account they kindle a fire everywhere on the day Âtarô of the month Dîn, and it forms an indication that winter has come. 12. In those five months the water of springs and conduits is all warm, for Rapîtvîn keeps warmth and moisture there, and one does not celebrate the period of Rapîtvîn. 13. As the day Aûharmazd of the month Fravardîn advances it diminishes the strength which winter possesses, and summer comes in from its own original dwelling, and receives strength and dominion. 14. Rapîtvîn comes up from below-ground, and ripens the fruit of the trees; on this account the water of springs is cold in summer, for Rapîtvîn is not there; and those seven months one celebrates the Rapîtvîn, and summer advances through the whole earth. 15. And yet in the direction of Hindûstân, there where the original dwelling of summer is nearer, it is always neither cold nor hot; for in the season which is the dominion of summer, the rain always dispels most of the heat, and it does not become perceptible; in the winter rain does not fall, and the cold does not become very perceptible. 16. In the northern direction, where the preparation of winter is, it is always cold; for in the summer mostly, on account of the more oppressive winter there, it is not possible so to dispel the cold that one might make it quite warm. 17. In the middle localities the cold of winter and heat of summer both come on vehemently. 18. Again, the year dependent on the revolving moon is not equal to the computed year on this account, for the moon returns one time in twenty-nine, and one time in thirty days, and there are four hours (zamân) more than such a one of its years; as it says, that every one deceives where they speak about the moon (or month), except when they say that it comes twice in sixty days. 19. Whoever keeps the year by the revolution of the moon mingles summer with winter and winter with summer. 20. This, too, it says, that the auspicious month Fravardîn, the month Ardavahist, and the month Horvadad are spring; the month Tîr, the month Amerôdad, and the month Shatvaîrô are summer; the month Mitrô, the month Âvân, and the month Âtarô are autumn; the month Dîn, the month Vohûman, and the month Spendarmad are winter. 21. And the sun comes from the sign (khûrdak) of Aries, into which it proceeded in the beginning, back to that same place in three hundred and sixty-five days and six short times (hours), which are one year. 22. As every three months it (the sun) advances through three constellations, more or less, the moon comes, in a hundred and eighty days, back to the place out of which it travelled in the beginning.

(30) And in periods of seven days the moon undergoes its changes. In the first week she becomes half moon; in the second, full moon; and in the third, in her wane, again half moon; and in the fourth she disappears. Further, as Seleucus the mathematician lays down, she has seven phases. First, from being invisible she becomes crescent-shaped, then half moon, then gibbous and full; and in her wane again gibbous, and in like manner half moon and crescent-shaped.

(7) Some authorities are of the opinion that the zodiac was originally divided into ten (instead of twelve) houses, or "solar mansions." In early times there were two separate standards--one solar and the other lunar--used for the measurement of the months, years, and seasons. The solar year was composed of ten months of thirty-six days each, and five days sacred to the gods. The lunar year consisted of thirteen months of twenty-eight days each, with one day left over. The solar zodiac at that time consisted often houses of thirty-six degrees each.

(12) And in the sixth 1951 a.m. week, in the fifth year thereof, Abram sat up through- out the night on the new moon of the seventh month to observe the stars from the evening to the morning, in order to see what would be the character of the year with regard to the rains, and he was alone as he sat and observed.
