The Sun and Moon produce effects which the ancients could not fail to notice. The rains, the tides, the fertility of the soil and the general comfort and well being of people were directly traceable to their influence. Apart from the Sun and Moon there were five other wandering stars or planets which seemed to move in harmony and also exerted their influence. The ancients knew these wandering stars as Mercury, Venus, Mars, Jupiter and Saturn. They decided to create seven day periods called weeks and named each week day after the various planets. Sun’s day became Sunday, Moon’s day became Monday and so on and so forth. That is how the now universally accepted week days came about.
It was also observed that the full Moon appeared twelve times in different parts of the sky before returning to its original position, and this gave birth to the “month” as we know it. Needless to say the definition of the “year”, the four seasons, day and night and various other phenomenon that we now accept without question, can all be traced back to the early observations of the Astrologers.
There are three fields known to science - magnetic, electric and gravitational which play a major part in the workings of the influences imparted by the planets as the planets in their orbits around the Sun get close to or further away from each other, major changes occur in these fields which in turn influence everything that has life on Earth.
It has been proved beyond a doubt that the phases of the Moon which is the fastest moving planet and the closest to the Earth affects the tides, the menstrual cycles of women, the growth of plants and the birth cycles of oysters and turtles. The Moon also has many links with human fertility as ovulation is promoted when it is full.
This is not to say that the other planets do not have a significant effect on our lives – they do in fact bring about similar effects although these are not easily observable.
