(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.

(2) First he produced, the celestial sphere, and the constellation stars are assigned to it by him; especially these twelve whose names are Varak (the Lamb), Tôrâ (the Bull), Dô-patkar (the Two-figures or Gemini), Kalakang (the Crab), Sêr (the Lion), Khûsak (Virgo), Tarâzûk (the Balance), Gazdûm (the Scorpion), Nîmâsp (the Centaur or Sagittarius), Vahîk (Capricornus), Dûl (the Waterpot), and Mâhîk (the Fish);

(5) When they tell us that a certain cold star is more benevolent to us in proportion as it is further away, they clearly make its harmful influence depend upon the coldness of its nature; and yet it ought to be beneficent to us when it is in the opposed Zodiacal figures.

When the cold planet, we are told, is in opposition to the cold, both become meanacing: but the natural effect would be a compromise.

And we are asked to believe that one of them is happy by day and grows kindly under the warmth, while another, of a fiery nature, is most cheerful by night- as if it were not always day to them, light to them, and as if the first one could be darkened by night at that great distance above the earth's shadow.

Then there is the notion that the moon, in conjunction with a certain star, is softened at her full but is malignant in the same conjunction when her light has waned; yet, if anything of this order could be admitted, the very opposite would be the case. For when she is full to us she must be dark on the further hemisphere, that is to that star which stands above her; and when dark to us she is full to that other star, upon which only then, on the contrary, does she look with her light. To the moon itself, in fact, it can make no difference in what aspect she stands, for she is always lit on the upper or on the under half: to the other star, the warmth from the moon, of which they speak, might make a difference; but that warmth would reach it precisely when the moon is without light to us; at its darkest to us it is full to that other, and therefore beneficent. The darkness of the moon to us is of moment to the earth, but brings no trouble to the planet above. That planet, it is alleged, can give no help on account of its remoteness and therefore seems less well disposed; but the moon at its full suffices to the lower realm so that the distance of the other is of no importance. When the moon, though dark to us, is in aspect with the Fiery Star she is held to be favourable: the reason alleged is that the force of Mars is all-sufficient since it contains more fire than it needs.

The truth is that while the material emanations from the living beings of the heavenly system are of various degrees of warmth- planet differing from planet in this respect- no cold comes from them: the nature of the space in which they have their being is voucher for that.

The star known as Jupiter includes a due measure of fire , in this resembling the Morning-star and therefore seeming to be in alliance with it. In aspect with what is known as the Fiery Star, Jupiter is beneficent by virtue of the mixing of influences: in aspect with Saturn unfriendly by dint of distance. Mercury, it would seem, is indifferent whatever stars it be in aspect with; for it adopts any and every character.

But all the stars are serviceable to the Universe, and therefore can stand to each other only as the service of the Universe demands, in a harmony like that observed in the members of any one animal form. They exist essentially for the purpose of the Universe, just as the gall exists for the purposes of the body as a whole not less than for its own immediate function: it is to be the inciter of the animal spirits but without allowing the entire organism and its own especial region to run riot. Some such balance of function was indispensable in the All- bitter with sweet. There must be differentiation- eyes and so forth- but all the members will be in sympathy with the entire animal frame to which they belong. Only so can there be a unity and a total harmony.

And in such a total, analogy will make every part a Sign.

(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.

(1) Since, however, every part of the heavens, every sign of the zodiac, all the motion of the heavens, every period of time according to which the world is moved, and all things contained in the wholes of the universe, receive the powers which descend from the sun, some of which are complicated with these wholes, but others transcend a commixture with them, the symbolical mode of signification represents these also, indicating “ that the sun is diversified according to the signs of the zodiac, and that every hour he changes his form .” At the same time, also, it indicates his immutable, stable, never failing, and at once collected communication of good to the whole world. But since the recipients of the impartible gift of the God are variously affected towards it, and receive multiform powers, from the sun, according to their peculiar motions, hence the symbolical doctrine evinces through the multitude of the gifts, that the God is one, and exhibits his one power through multiform powers.

(20) Aûharmazd also knew this, through omniscience, that within these nine thousand years, for three thousand years everything proceeds by the will of Aûharmazd, three thousand years there is an intermingling of the wills of Aûharmazd and Aharman, and the last three thousand years the evil spirit is disabled, and they keep the adversary away from the creatures.

(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.

(3) "And the Fate and the sphere over which they rule, I have changed and brought it to pass that they spend six months turned to the left and accomplish their influences, and that six months they face to the right and accomplish their influences. For by command of the First Commandment and by command of the First Mystery Yew, the Overseer of the Light, had set them facing the left at every time and accomplishing their influences and their deeds.
