The ancient wisdom of our heavens is seldom taught to us in today's modern society but it does not take much to uncover the hidden knowledge, and just because we are rarely educated in astronomy does not at all mean it is no longer relevant to the way we are, the way we live, and our destined fate. In fact, the more we learn about both astronomy and astrology the more we come to realize just how accurate it is.
Wise people in the past; Jesus and his disciples, Hypatia, Leonardo Da Vinci, Nostradamus, Carl Jung, Edgar Cayce, etc, all realized how the alignment of the planets, stars, sun, and moon in our solar system effect our existance, behaviour, and events.
Take a look at a picture of the Western Zodiac and where each zodiac sign is located in the sky as constellations. Each zodiac is of an element (Earth, Air, Fire, Water), and there are 3 zodiacs per element. For example, Virgo, Taurus, and Capricorn are the 3 zodiacs of the Earth element. Due to where these 3 zodiac signs are located in the sky, if you draw a line to attach these 3 Earth signs it will form a perfect triangle. A holy trinity. So it is no coincidence when it is said that these 3 Earth signs are best suited as mates (Virgo + Capricorn, Taurus + Virgo, etc).
Doing the same to the other zodiacs which share the same element (ie: Air, Fire, Water) will create perfect triangles as well. (Although unlike the 3 Earth signs, other elements may not be suitable with a sign from the same element such as Air + Air.)
Now take a look at a picture of the Eastern (Asian) Zodiac. Their zodiacs and their best suited mates attached by lines also form perfect triangles (ie: Horse, Tiger, Dog).
Other planets have interesting facts concerning their rotation. For example, Mercury shows the opposite side each time. Whereas the Moon only shows us the same one side (hence the song by Pink Floyd; The Dark Side of the Moon).
Now let's look at Stonehenge. The stones had been placed rather strategically as though to construct a gigantic clock. Could each rock have represented each zodiac sign? This might explain the stone altar in the centre. Perhaps it was a birthing table so that the soul of the child being born would find it's way from it's birth planet in the sky above to the body on the altar below. The stones would be aligned accurately with the alignment of the planets. This explains why we have the behaviour and characteristics of the zodiac star constellation and planet we are born under at the time and date of our birth.
There are 12 zodiacs but there had originally been 13. It had been removed by astronomers because that 13th constellation did not lay along the circular line in complete alignment with the other 12. However, it does play a very important role because it is Ophiuchus (aka Asclepius); the Healer. It is now portrayed as a male symbol but it had previously been a female symbol. She holds two other star constellations in her hands; Serpen Cauda (Serpent's Tail) and Serpen Caput (Serpent's Head). So she is a female healer which holds a snake in each of her hands. This is why the ancient Minoan Greeks depicted her as the "Snake Goddess". Thus snakes are often used as a symbol for healing. Even medical associations today still use this 2 snake symbol. It is called a caduceus. The ancient Greeks later had Hermes; the Messenger of the Gods, hold a caduceus (a staf with wings at the top and 2 snakes entwined up the staf). Hermes was the Guide of the Dead and also the God of Medicine. He had the power to heal. Prior to Greek God Hermes the Egyptian God Thoth was also God of the Dead and a Healer.
Why was this 13th zodiac sign removed from the zodiac? Is it not important? Indeed everything in the sky is relevant. To remove or make changes could have disasterous results. Even the Gnostic messenger Jesus realized the importance of having 13 present. He had 12 disciples and he (also a "Healer") made 13 in total.
The Snake Goddess; Ophiuchus was not the only star constellation that was changed. Orion; the Hunter may very well have originally been the Greek Goddess Artemis; the Hunter. There is the myth that Artemis's brother Apollo did not like Orion (son of Poseiden) hunting with Artemis so Apollo had tricked Artemis into killing Orion with her arrow. Ophiuchus the son of Apollo then healed Orion. This angered Hades the God of the Underworld so Zeus had Scorpius sting Ophiuchus but this upset Apollo so Zeus placed Ophiuchus in the sky as a constellation but not as a zodiac. Instead Scorpio took his place in the zodiac. There are many varied versions to this myth, but the important fact to note is that most if not all of these ancient myths were really just stories to help students in those days understand star constellations they were studying. Yes Ophiuchus is a constellation in the sky and Scorpius (Scorpio) is indeed located October 22-November 23 where Ophiuchus would have been had he (or she) been part of the zodiac circle.
By studying the rotation of planets in our solar system, Hypatia (370 AD-415 AD) revolutionized our knowledge of astronomy by creating the Astrolabe (Star Taker) which sailors later used to navigate the seas by locating the North Star (similar to how a compass works) in alignment with the planets to find latitude. Sailors in the south do the same by instead locate the star constellation Crux; Southern Cross. (See: Astrolabe)
Obviously to study astronomy and astrology is to re-educate ourselves with ancient wisdom. The Templars had studied astronomy and this is verified by noting the location of their temples and churches. Each temple they built was aligned in exact coordinates with their other temples to form perfect pentacles. Leonardo Da Vinci had also studied astronomy and geometry while he was a Freemason.
You can now add yourself to the list of those intellectuals who study astronomy and acknowledge it's great importance.
