Every wise caveman knew not to hunt deer during a full moon day. The reason why is because a full moon shows you before you can get to the parse so you hunted on the night before. Evidence shows that the Neanderthal did not have knowledge of Astrology. Neanderthal campsites close to rivers that we know had salmon runs every year. But there are no salmon bones at the camps. Astrology’s beginnings were indeed humble. Early cavemen used astrology for survival. The ability to know the habits of others animals was one of his greatest assets in survival. It told him not only when to hunt, when to fish or so on. It also told him when to celebrate around the third weak in December. North on the twenty first of December. The Celtic people of northern Europe were firm pagons and lived their lives to Astrological rhythms. When Rome wanted to incorporate the Celts into Christianity they would not move to Christianity without their winter Solstice Holiday. Celts had many holidays that are now in our calendar but that are how Christianity got Christmas. Astrology also predates all religions. The whole concept of heaven is based in Astrology. Most of the ancients Gods had celestial if not zodiacal roots. The greatest magi. They would have to have known years in advance.
Modern Astrology owes its foundations to the Hellenic Greeks. Ptolomy wrote the principia in the late Hellenic Greek period. Geocentric Tropical Astrology means with Earth at the center of the chart. Astrology is not only Earth based but also for exact position the nativity in latitude and longitude. Tropical means that the location of zero degrees Aries is not at a fixed point in the sky. That is it floats through the zodiac according to where the spring Equinox falls. Zero degrees Aries progresses through the zodiac as the Spring Equinox progresses, for Modern astronomy needs a fixed sky so they do not progress their map of the sky as Astrologers. They need to be able to return to a fixed point amongst the stars so they use what is called the sidereal zodiac.
