It was especially used to represent geometrically the periodic apparent retrograde motion of the outer planets, Mars, Jupiter and Saturn, which we now know to be due to the annual revolution of the earth around the sun, but which in the Ptolemaic astronomy were taken to be real.
Gold, the most perfect metal, had the symbol of the Sun, 0; silver, the semiperfect metal, had the symbol of the Moon, 0j; copper, iron and antimony, the imperfect metals of the gold class, had the symbols of Venus Mars and the Earth tin and lead, the imperfect metals of the silver class, had the symbols of Jupiter 94, and Saturn h; while mercury, the imperfect metal of both the gold and silver class, had the symbol of the planet,.
His first book - Saturn and his System - was published in the same year, at his own expense.
3 represent the two orbits, the sun being at C. We know that the period of Jupiter is nearly twelve years, and that of Saturn a little less than thirty years.
The annual motion of Jupiter is nearly 30°, that of Saturn a little more than 12°.
The annual mean motions, with the corresponding combinations, are as follows Jupiter: - n = 30° 349043 Saturn: - n' = 12.221133 2n=60 69809 5n'=61.10567 5n'-2n= o 40758 If we make a more accurate computation of the conjunctions from these data, we shall find that, in the general mean, the consecutive conjunctions take place when each planet has moved through an entire number of revolutions +242.7°.
Amongst the fruits of his industry may be mentioned a laborious investigation of the disturbances of Jupiter by Saturn, the results of which were employed and confirmed by L.
This process, which reached its culmination in the post-Khammurabic period, led to identifying the planet Jupiter with Marduk, Venus with Ishtar, Mars with Nergal, Mercury with Nebo, and Saturn with Ninib.
The Babylonian computers were not only aware that Venus returns in almost exactly eight years to a given starting-point in the sky, but they had established similar periodic relations in 4 6, 59, 79 and 83 years severally for Mercury, Saturn, Mars and Jupiter.
These five planets were identified with the great gods of the pantheon as follows: - Jupiter with Marduk, Venus with the goddess Ishtar, Saturn with Ninib, Mercury with Nebo, and Mars with Nergal.
Saturn for lead, Venus for copper, and Mars for iron, and the belief that the colours of flowers ' The Egyptians believed that the medicinal virtues of plants were due to the spirits who dwelt within them.
Discarding those of Uranus, in which the orbits of the satellites are highly inclined to the ecliptic, and in which manifestly some exceptional influences have been at work, we find that the satellites revolve around the primaries also in the same direction (Exceptions are Saturn ix.
In addition to the common treasury, supported by the general taxes and charged with the ordinary expenditure, there was a special reserve fund, also in the temple of Saturn, the aerarium sanctum (or sanctius), probably originally consisting _of the spoils of war, afterwards maintained chiefly by a 5% tax on the value of all manumitted slaves, this source of revenue being established by a lex Manlia in 357.
There is more than one meaning of Saturn discussed in the 1911 Encyclopedia.
(11) The Temple of Saturn: site unknown.
The immediate results of the clearer definition obtained were the detection of a satellite to Saturn (the sixth in order of distance from its primary), and the resolution into their true form of the abnormal appendages to that planet.
The alchemists designated it by the sign of Saturn k.
The head of the divine hierarchy of Mithras was Infinite Time - Cronus, Saturn; Heaven and Earth were his offspring, and begat Ocean, who formed with them a trinity corresponding to Jupiter, Juno, and Neptune.
Of these the most conspicuous was offered by the opposite inequalities of Jupiter and Saturn, which the emulous efforts of L.
The long-sought cause of the "great inequality" of Jupiter and Saturn was found in the near approach to commensurability of their mean motions; it was demonstrated in two elegant theorems, independently of any except the most general considerations as to mass, that the mutual action of the planets could never largely affect the eccentricities and inclinations of their orbits; and the singular peculiarities detected by him in the Jovian system were expressed in the so-called "laws of Laplace."
What is thus shown to be possible would, of course, be necessary if we went on, with the astronomer Kepler, to identify the star of the Magi with the conjunction of the planets Jupiter and Saturn which occurred, in the constellation Pisces, in May, October and December of 7 B.C.'
After a rough estimate of the perturbations it must sustain from the attraction of the planets, he predicted its return for 1757,-a bold prediction at that time, but justified by the event, for the comet again made its appearance as was expected, though it did not pass through its perihelion till the month of March 1759, the attraction of Jupiter and Saturn having caused, as was computed by Clairault previously to its return, a retardation of 618 days.
In the Egyptian astronomy, the order of the planets, beginning with the most remote, is Saturn, Jupiter, Mars, the Sun, Venus, Mercury, the Moon.
If, then, the first hour of a day was consecrated to Saturn, that planet would also have the 8th, the 15th, and the 2 2nd hour; the 23rd would fall to Jupiter, the 24th to Mars, and the 25th, or the first hour of the second day, would belong to the Sun.
Halley's most notable scientific achievements were - his detection of the "long inequality" of Jupiter and Saturn, and of the acceleration of the moon's mean motion (1693), his discovery of the proper motions of the fixed stars (1718), his theory of variation (1683), including the hypothesis of four magnetic poles, revived by C. Hansteen in 1819, and his suggestion of the magnetic origin of the aurora borealis; his calculation of the orbit of the 1682 comet (the first ever attempted), coupled with a prediction of its return, strikingly verified in 1759; and his indication (first in 1679, and again in 1716, Phil.
We have also seen with it several times the five satellites of Saturn, in viewing of which this telescope had the advantage of the Huygenian at the time when we compared them; for, being in summer, and the Huygenian telescope being managed without a tube, the twilight prevented us from seeing in this some of these small objects which at the same time we could discern with the reflecting telescope."
Kewan is probably the old Babylonian Ka(y)awanu, the planet Saturn, another (the Akkadian) name for which is Sakkut, which appears as Siccuth in the earlier part of the verse.
Centre of force - as the Earth, Saturn, &c. - at which it is farthest from the central body.
Again, Picus is the first king of Latium, son of Saturn and father of Faunus.
Sometimes he kissed the feet or knees of the images of the gods themselves, and Saturn and Hercules were adored with the head bare.
There is a tradition that the Ka`ba was a temple of Saturn (Shahrastani, p. 431); perhaps the most distinctive feature of the shrine may be sought in the sacred doves which still enjoy the protection of the sanctuary.
Of the planets five were recognized - Jupiter, Venus, Saturn, Mercury and Mars - to name them in the order in which they appear in the older cuneiform literature; in later texts Mercury and Saturn change places.
Before the close of 1610 the memorable cycle of discoveries begun in the previous year was completed by the observation of the ansated or, as it appeared to Galileo, triple form of Saturn (the ring-formation was first recognized by Christiaan Huygens in 1655), of the phases of Venus, and of the spots upon the sun.
At this point Saturn will have moved 240° and Jupiter an entire revolution+240°, making 600°.
The next conjunction will take place along CS I, and the third after the initial one will again take place near the original position JQ, Jupiter having made five revolutions and Saturn two.
Using a powerful and elaborate analysis, Adams ascertained that this cluster of meteors, which belongs to the solar system, traverses an elongated ellipse in 334 years, and is subject to definite perturbations from the larger planets, Jupiter, Saturn and Uranus.
In the other letters written in 1685 and 1686 he applies to Flamsteed for information respecting the orbits of the satellites of Jupiter and Saturn, respecting the rise and fall of the spring and neap tides at the solstices and the equinoxes, respecting the flattening of Jupiter at the poles (which, if certain, he says, would conduce much to the stating the reasons of the precession of the equinoxes), and respecting the difference between the observed places of Saturn and those computed from Kepler's tables about the time of his conjunction with Jupiter.
" Your information," he says, " about the errors of Kepler's tables for Jupiter and Saturn has eased me of several scruples.
