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.
The science has never been universal in its acceptance, though it is safe to say that, with its countless adherents in the East and the ever-increasing number of its advocates in the West, there is no faith which has a more universal application than the belief in the influence of the heavenly bodies over the destinies of human beings.
Incomplete as it must needs be, it is yet a veritable science both as to its principles and practice.
It claims for itself a place among the sciences for the sole reason that it is capable of mathematical demonstration, and deals only with the observed positions and motions of the heavenly bodies; and the man who holds to the principia of Newton, the solidarity of the solar system, the interaction of the planetary bodies and their consequent electrostatic effects upon the Earth, cannot, while subject to the air he breathes, deny the foundation principles of astrology.
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.
