Astrologers the world over have always considered that the Moon exerts a great influence over human generation. We know that it plays a most important part in the normal functions of the human body, more especially as affecting the blood pressure. This may be the reason for its marked influence upon persons in certain forms of insanity. In my _Manual of Astrology_ I have shown beyond all doubt that it exerts a powerful influence in the matter of sex, and also that there is an astronomical relation between the Moon’s motion and the process of generation culminating in birth. The ancients have said that the various months of parturition are under the successive influence of the planets, Saturn, Jupiter, etc., thus— 1st month under Saturn: Plasmic basis. 2nd month under Jupiter: Amnionic development. 3rd month under Mars: Limbal growth. 4th month under Sun: Quickening. 5th month under Venus: Sex distinction. 6th month under Mercury: Brain development. 7th month under Moon: Precocious birth. 8th month under Saturn: Abortive birth. 9th month under Jupiter: Normal birth. Swedenborg has said that all children come from the Moon. There is a Greek legend which associates Selene and Selinon, confounding the Moon with the parsley plant, and old women to-day tell their inquisitive grandchildren that they were brought from the parsley bed. In the Greek Mysteries the soul passes through the sphere of the Moon in its descent to the Earth, taking upon itself a silver vestment, which is the astral or lunar body, as distinguished from the imperishable solar body proper to the incarnating ego. The Hindus, as has been shown elsewhere, make all their astrological calculations from the place of the Moon, and the horoscope of birth is converted into terms of the Moon’s position at the moment of that event. Also they reckon the periodic effects from the same position. It is therefore obvious that the astrologer at all events has not overlooked the enormous influence that this orb is believed to exert upon mundane affairs and human life. As we have seen, the ancients, with whom these beliefs arose, were keen observers of natural operations, and depended entirely on their unaided and unprejudiced observations for whatever knowledge they possessed. They regarded the Moon as the purveyor or carrier of astral influence. Life and energy were generated from the Sun, the vital centre of our system. This life was modified by reflection of rays from the various planets, which transmitted the Sun’s rays to this Earth in altered electrical and magnetic conditions, and the Moon, circling round the Earth at great velocity, collected and distributed these influences upon our nether sphere. The notion is at least cosmical and coherent. If it also be true it is of the utmost importance to us as terrestrials.
