Babylonian astronomers split the ecliptic into 12 equal “signs” at the end of the 5th century BC, analogous to 12 schematic months of 30 days each. The first known celestial coordinate system was created when each sign contained 30 degrees of celestial longitude. According to contemporary astronomical estimates, the zodiac was first used between 409 and 398 BC, during Persian dominance, and most likely within a few years of 401 BC. Unlike modern astrologers, who place the beginning of the sign of Aries at the position of the Sun at the Northern Hemisphere’s vernal equinox (March equinox), Babylonian astronomers fixed the zodiac in relation to stars, placing the beginning of Cancer at the “Rear Twin Star” ( Geminorum) and the beginning of Aquarius at the “Rear Star of the Goat-Fish” ( Capricorni).
Since Babylonian times, the time of year when the Sun is in a certain constellation has altered due to equinox precession; the point of March equinox has moved from Aries to Pisces.
They formed an appropriate basis of reference for formulating predictions about a planet’s longitude because the divide was made into equal arcs of 30 each. However, Babylonian observational measurement techniques were still in the early stages of development. They used a group of “normal stars” near the ecliptic (9 degrees latitude) as observational reference points to help place a planet within the ecliptic coordinate system.
A planet’s location in Babylonian astrological journals was usually stated in terms of a zodiac sign alone, rather than particular degrees within a sign. When degrees of longitude were given, they were stated in relation to the 30 of the zodiacal sign, rather than the continuous 360 ecliptic. The positions of prominent astronomical phenomena were estimated in sexagesimal fractions of a degree in astronomical ephemerides (equivalent to minutes and seconds of arc). The daily locations of a planet were less important in daily ephemerides than the astrologically significant times when the planet moved from one zodiac sign to the next.

What was the very first zodiac sign?
Aries () (Greek: K, Latin for “ram”) is the first zodiac sign, spanning the first 30 degrees of celestial longitude (0 ).
What is the origin of zodiac astrology?
) and extended to India, but it was in Greek society during the Hellenistic period that it took on its Western shape. Astrology was introduced to Islamic culture as part of the Greek legacy, and it was then reintroduced to European society through Arabic studies in the Middle Ages. According to Greek mythology, the sky is split into 12 zodiac constellations, and the bright stars that appear at regular intervals have a spiritual impact on human events. Astrology was also important in ancient China, and it became normal practice in imperial times to have a horoscope cast for each newborn child and for all significant life events. Despite the fact that the Copernican philosophy broke the geocentric worldview required by astrology, interest in the subject has persisted into contemporary times, and astrological signs are still generally considered to determine personality.
When did the zodiac signs begin?
The 12 zodiac signs, one of the earliest notions of astrology, were devised by the Babylonians around 1894 BC. The Babylonians lived at Babylon, which is roughly where modern-day Iraq is located. Babylon was one of the most prominent ancient Mesopotamian towns.
Who is the creator of the zodiac?
According to NASA, the Babylonians had already constructed a 12-month calendar based on the phases of the moon when they created the zodiac. Despite the fact that they identified 13 constellations that make up the zodiac, they decided to leave one out so that the zodiac signs would coincide better with their 12-month calendar.
Ophiuchus, pronounced “O-few-cus,” is that unfortunate, long-forgotten constellation.
But, before all of you Aries, Cancers, and Leos start making fun of your new Ophiuchus friends, keep in mind that the addition of this 13th constellation shifts every zodiac sign’s time frame slightly, which means that, while I’ve loved my life as a textbook Pisces, I discovered that I’m now an Aquarius after doing my research. (Gasp!)
Although 3,000 years old, this information reappeared this year when NASA disclosed scientific data regarding the Earth’s axis, which has moved and no longer points in the exact same direction as it previously did, affecting the amount of time each constellation is visible in the sky.
Many ardent fans of astrology (and Twitter) believed NASA had “added” a sign to the zodiac, causing havoc with the signs we all know and love. That, however, is not the case. NASA omitted an astrological symbol from the design. They “simply done the math,” according to their Tumblr blog post. If you want to point the finger, it should go to the ancient Babylonians for leaving Ophiuchus out of the picture in the first place.
What was Jesus’ take on astrology?
I believe that God created astrology as a tool for us to better understand ourselves and to use as a spiritual tool. Numerous bible texts, in my opinion, support astrology. As a Christian, I try to remember what Jesus said. “There shall be signs in the sun, moon, and stars,” Christ predicted in Luke 21:25, referring to the importance of astrology. He explains the value of astrology with his pupils, as well as how it might be used as a sign of his return. Why would Jesus provide us this critical knowledge if we are not intended to understand the energies of the planets and signs, and if he was actually against it? Just as the three wise men knew Jesus would be born under the star in the sky that led them to him lying in the manger, Jesus warned us that when he returns, there will be signals in the sky.
Who developed the 12 signs of the zodiac?
The 12 zodiac signs Aries (March 21-April 19), Taurus (April 20-May 20), Gemini (May 21-June 20), Cancer (June 21-July 22), Leo (July 23-Aug. 22), Virgo (Aug. 23-Sept. 22), Libra (Sept. 23-Oct. 22), Scorpio (Oct. 23-Nov. 21), Sagittarius (Nov. 22-De These Western, or tropical, zodiac signs were named after constellations and paired with dates based on their apparent relationship to the sun’s position in the sky.
By 1500 BC, the Babylonians had divided the zodiac into 12 equal signs, with constellation names that were similar to those we know today, such as The Great Twins, The Lion, and The Scales, and these were later adopted into Greek divination. These 12 signs were popularized by the astronomer Ptolemy, author of the Tetrabiblos, which became a key work in the history of Western astrology.
“Ptolemy codified the idea that there were 12 signs of the zodiac that were 30 wide and that the sun travelled through these signs on a regular basis throughout the year,” says Odenwald. According to the Oxford English Dictionary, the word “zodiac” is derived from a Greek term meaning “sculpted animal form,” and the sequence in which the signs are normally enumerated is also derived from that period.
What is the zodiac’s age?
2,500 years ago, during the “Age of Aries,” the zodiac system was created in Babylonia. It is assumed that the precession of the equinoxes was unknown at the time. In modern use of the coordinate system, the option of interpreting the system as sidereal, with the signs fixed to the stellar backdrop, or tropical, with the signs fixed to the point (vector of the Sun) at the March equinox, is offered.
The tropical technique is used in Western astrology, but the sidereal approach is used in Hindu astrology. As a result, the once-unifying zodiacal coordinate system is gradually drifting apart, with a clockwise (westward) precession rate of 1.4 degrees each century.
This means that the tropical sign of Aries is currently located somewhere within the constellation Pisces, according to the tropical zodiac used in Western astronomy and astrology (“Age of Pisces”).
The ayanamsa, ayan meaning “transit” or “movement,” and amsa meaning “little part,” or the movement of equinoxes in small sections, is taken into account by the sidereal coordinate system. It is unclear when Indians first became aware of the precession of the equinoxes, but Bhskara II’s 12th-century treatise Siddhanta Shiromani contains equations for measuring the precession of the equinoxes, and claims that his equations are based on some lost Suryasiddhanta equations plus the Munjaala equation.
Hipparchus is credited with discovering precession in 130 BC. In the seventh book of his 2nd century astronomical literature, Almagest, Ptolemy draws from Hipparchus’ now-lost work “On the Displacement of the Solstitial and Equinoctial Points,” in which he describes the phenomena of precession and calculates its importance. Ptolemy stated that in Greek mathematical astrology, the zodiac was always started at the vernal equinox, and this point was always referred to as “the first degree” of Aries. Because its starting point travels across the circle of backdrop constellations over time, it is known as the “tropical zodiac” (from the Greek word trpos, turn).
In Geminus of Rhodes’ 1st century BC astronomical book, the principle of the vernal point acting as the first degree of the zodiac for Greek astronomers is described. In contrast to the previous Chaldean (Babylonian) system, which placed these points within the zodiac signs, Geminus says that Greek scientists of his period correlate the initial degrees of the zodiac signs with the two solstices and the two equinoxes. This shows that, contrary to popular belief, Ptolemy just defined Greek astronomical conventions and did not invent the tropical zodiac theory.
In his astrological text, the Tetrabiblos, Ptolemy demonstrates that the principle of the tropical zodiac was well known to his forefathers, explaining why it would be a mistake to associate the seasonally aligned zodiac’s regularly spaced signs with the irregular boundaries of the visible constellations:
The equinoctial and tropical points are used to determine the beginnings of the signs, as well as the starts of the terms. This rule is not only stated explicitly by writers on the subject, but it is further demonstrated by the constant proof that their natures, effects, and familiarities have no other origin than the tropics and equinoxes, as has already been demonstrated. And, if other beginnings were permitted, it would either be necessary to exclude the natures of the signs from prognostication theory, or impossible to avoid error in retaining and employing them, because the regularity of their spaces and distances, on which their influence is based, would be invaded and broken into.
