Origin and development the zodiac signs
It is believed that humans started observing the stars about 5000 years ago.The origin of astrology and the constellations we are familiar with today are said to be found in the Euphrates and Tigris. When the Sumerians immigrated to these areas around 3000 BC, they probably already brought their own astronomy with them. The Babylonians, who founded first great empire in the two-stream region, took over the astronomy and the constellations of the Sumerians and set up the first observatories. The ancient Greeks used the images from the two-river region but then surrounded them with their own myths and stories.
They still combined free stars into new pictures and supplemented them. If no suitable myths were found, they were invented and poeticized.
In the 17th and 18th centuries, there were several attempts to Christianize the pagan constellations. For example, the images of the zodiac should become the Twelve Apostles. But these attempts were not really successful. In 1603, the Augsburg astronomer Johann Bayer made a map of the night sky and in this map he used the Greek constellations as drawings.
Then in the 19th century, astrology experienced a renaissance in Europe that continues to this day.
