Neptune revolves around the Sun in its distant orbit once in about 165 years.
Uranus completes its orbital revolution in 84 years, Jupiter in 12 years, Mars in about 15 months, Venus in 11 months, and Mercury in 18 weeks.
It is believed that the present work will be of considerable assistance to those who seriously contemplate an initial study of the science of horoscopy, and although it by no means exhausts what is known on the subject, yet it will be found accurate and reliable as far as it goes, and will enable any one of ordinary intelligence to test the claims of Astrology for himself.
This is as much as can be expected in the limits of a small handbook.
Mercury and Venus will then appear to revolve around the Sun while the Sun revolves around the Earth, sometimes being between the Earth and the Sun, which is called an Inferior conjunction, sometimes on the further side of the Sun away from the Earth, as at their Superior conjunction; and again, at other times to the right or left of the Sun, in East or West elongation.
The other planets, having orbits greater than that of the Earth, will appear to revolve around it at constantly varying distances and velocities.
The Earth follows the same laws as all other bodies of the same system.
Not that these discoveries overturned the whole system of astrology, as some have imagined and foolishly stated, or that they negatived the conclusions drawn from the observed effects of the seven anciently known bodies of the solar system, but it became possible after a lapse of time to fill in the blank spaces and to account for certain events which had not been traced to the action of any of the already known planets.
Among the Hindus we have the classical writers Garga, Parashara, and Mihira, together with their legions of commentators.
The Assyrian records are full of astrological allusions regarding the influence of planetary conjunctions and stellar positions.
The Greek mythology is nothing but a vast system of cosmographical astrology, and there is no other history in it than what you may read in the constellations of the heavens and the corresponding evolution of the human race. Hipparchus, Hippocrates, Thales, Galenius, and others subscribed an intelligent belief in its principles.
To Claudius Ptolemy, however, we are indebted for the first concise and scientific statement of its principles and practice, so far as Europe is concerned.
It is not possible within the limits of a small handbook such as this to adequately consider the philosophic paradox which makes of Freewill in man a “necessity in play”; but it is obvious that the concept is not altogether unscientific, seeing that it is customary to speak of the “free path of vibration” in chemical atoms while at the same time it is known that these atoms have their restricted characteristics, modes of motion, &c., and are all subject to the general laws controlling the bodies of which they form integral parts.
