At astronomy's high point in antiquity during the hellenistic age from around 200 BC - 200 AD, the vernal equinox in the northern hemisphere was situated on the border between the fixed star constellations of Aries and Pisces. Astrologers at the time divided the circle of the ecliptic into twelve equal segments of 30° using this zero-point as a frame of reference. These segments were given the same names as the fixed star constellations lying behind them. It is important to distinguish these 30° degree segments of the ecliptic (or signs of the zodiac) from the background of fixed star constellations carrying the same name, which are both vaguely defined and of irregular size.

he vernal equinox in the northern hemisphere - 20th or 21st March - is the day on which day and night are of equal length. This point is mathematically defined using the point of intersection between the equator and the earth's orbit around the sun, i.e. the ecliptic. The celestial equator is given by the position of the earth's axis in space. If this axis were to remain stable the vernal equinox on 21st March would be a fixed point in space.
      However, the earth's axis is not stable. The earth is not a perfect sphere, but flattens out at the poles and bulges at the equator. It reacts to the the gravitational influence of the sun and moon like a spinning top whose rotation is distorted by some external force: this causes what has been termed the earth's precession - which means that the earth's axis itself rotates in a circle, leading to a conical movement around the fixed pole of the ecliptic. One complete rotation around this cone takes roughly 26000 years. This shifting of the earth's axis causes the celestial equator to shift so that the point of intersection between it and the ecliptic - the vernal equinox - moves from east to west along the circle of the ecliptic, i.e. in the opposite direction to the standard zodiac.

It takes about 26000 years for the vernal equinox to make one complete revolution around the ecliptic, i.e. through all of the twelve constellations. It takes around one twelfth of this time - roughly 2160 years - to traverse one sign of the zodiac. In antiquity the vernal equinox was situated between the signs of Pisces and Aries, and because of its retrograde movement through the zodiac is at present situated in Aquarius, just

barely inside the border zone between the constellations of Pisces and Aquarius. In other words, the so-called Age of Aquarius has begun

Here are the ages and how they have effected the world.

The Age of Leo (The Leonian Age)

"The Golden Age". The major event in this age was deglaciation of what now constitutes much of the modern habitable world. The deglaciation ultimately caused a 300-foot (90 m) rise in the sea level. The sign Leo is a Fire sign and is mythically ruled by the Sun in astrology,

The Age of Cancer (The Cancerian Age)

: "The Age of the Great Mother." Cancer is ruled by the Moon, and is associated with the process of bearing, birthing, nurturing, and protecting. In astrologic mythology this age marks the beginning of civilization, with domestication of farm animals and nomadic people settling down to living in permanent dwellings.

Religious similarities

Widespread evidence of the mothe goddess  in the Near East (the 'mother' archetype in all shapes and forms is always related to the sign Cancer).

The Age of Gemini (The Geminian Age)

"The Age of Communication, Trade and the Twins"

During this mythological age writing developed,  and trade started to accelerate. The constellation can be seen as two people holding hands (thought to be twins), believed by some[who?] to be symbolic for trade and communication of peoples. In myths associated with the constellation of Gemini, both writing (including literature, newspapers, journals, magazines, and works of fiction) and trade (including merchants) are traditional archetypes belonging to the sign of Gemini

The Age of Taurus (The Taurean Age)

"The Age of Earth, Agriculture, and the Bull" This age is claimed to have occurred approximately around the time of the building of the Pyramids in Egypt.

Religious similarities

Bull worshiping cults began to form in AssyriaEgypt, and Crete during this age.

Ankh: thoracic vertebra of a bull - Egyptian symbol of life

Worship of Apis, the bull-deity (see also Bull (mythology)), the most important of all the sacred animals in Egypt, said to be instituted during the Second Dynasty of the Early Dynastic Period of Egypt and worshipped in the Memphis region until the New Kingdom (16th century BC).

When Moses was said to have descended from the mountain with the ten commandments (c. 17th – 13th century BC, the end of the Age of Taurus), some of his people or followers were found by him to be worshipping a golden bull calf. He instructed these worshippers to be killed. This represents Moses "killing" the bull and ending the Age of Taurus, and ushering in the Age of Aries, which he represents

The Age of Aries (The Arian Age)

The Age of War, Fire, and the Ram"

Historical similarities

Aries represents a Fire symbol as well as bold actions, a lot of these behaviors can be seen during any age. However, the themes emphasized during this age relate to courage, initiative, war, and adventure. Nations during this age such as the expanding empires of ChinaPersiaGreece, and Rome, are often cited as examples of the archetypes of Aries in action. Also the Aries constellation shows a ram running. This could correspond with the sacrifice of Abraham's Ram. While the number of names containing the sound of the ram during this period is noted: Ra (Sun God), Ram, Rama, Brahman, Brahma, Abram/Abraham, Amon Ra, and Ramses I.[The battering ram was employed by the Assyrians, Greeks, and Romans with great success during this time – (The symbol of

Mars, the planetary ruler of Aries, evokes this interpretation.) According to the Roman state religion, the Roman people were the "Sons of Mars".

Aries is associated with the metal iron, and iron ore was for the first time smelted and worked into iron swords in Anatoliaduring the early phase of this era, replacing the heavier, softer-metalled, duller-edged bronze swords of the previous Taurus Age.

Traits of Aries such as 'initiative' may suggest the explosion of originality in the development of social aspects, sciences and arts in regions such as Ancient Greece but at the same time traits such as 'Impulsivity' may be attributed to the various Wars of the time.

Religious similarities

The Age of Aries ushered in efforts to replace polytheism with monotheism. The earliest known attempt was by the Egyptian Pharaoh Akhenaten, who, in about 1350 BC, decreed the Sun God Aten to be the supreme deity, apparently in reaction to his earlier lack of inclusion in religious rites by his family. After his death, however, power reverted to the original polytheistic priests, who re-established the old religion. Speculation (including that of Freud) has it that later, during the reign ofRamesses IIMoses was influenced by rumour of Akhenaten's revolutionary idea, and grasped the idea of a single supreme God, who especially favoured his people, as an inspirational mechanism that best suited his people held in bondage. The symbol of Aries can be seen as representing the power of multiple gods streaming down into a single god-head.

Moses was an early Biblical Hebrewreligious leader, lawgiver, prophet, and military leader, condemns his own people upon finding them worshiping a 'golden calf' (a symbol of the previous Age of Taurus and of the worship of the bull deity) after coming down Mount Sinai. These events may have occurred during the Age of Aries

The Age of Pisces (The Piscean Age)

"The Age of Monotheism, religion, and the Fish"

The age of Pisces began c. 5 AD and will end c. 2012 AD. With the story of the birth of Christ coinciding with this date,[53]many Christian symbols for Christ use the astrological symbol for Pisces,[54] the fishes.[55] Jesus bears many of the temperaments and personality traits of a Pisces,[56] and is thus considered an archetype of the Piscean.[57] Moreover, thetwelve apostles were called the "fishers of men," early Christians called themselves "little fishes," and a code word for Jesus was the Greek word for fish, "Ikhthus."[55] With this, the start of the age, or the "Great Month of Pisces" is regarded as the beginning of the Christian religion.[58] Saint Peter is recognized as the apostle of the Piscean sign.


The Age of Aquarius (The Aquarian Age)

as the personification of the constellation of Aquarius is a man carrying pitchers of water.

"The Age of Freedom, Technology (especially space travel and electricity), and the Water Bearer"
There is an expectation that the Aquarian Age will usher in a period of group consciousness.
[66] Marcia Moore and Mark Douglas claim that the lighting up of the earth artificially by electricity is a sign of the Age of Aquarius. The Age of Aquarius advances a purification of our inner spirit selves, effecting our outer physical selves, while also mirroring these purifying changes into the living planetary system and the biosphere as part of a cleaning up or cleansing of self and planet. The water-bearer may symbolize widespread transparent, peaceful, neighborly, and sustainable living. Furthermore, they see the appearance of dictators, self-expression, and the rising influence of the entertainment industry are linked to the Aquarian Age by its opposite sign Leo.


Popular culture

In popular culture, the expression "Age of Aquarius" usually refers to the heyday of the hippie and New Age movements of the 1960s and 1970s. The 1967 successful musical Hair, with its opening song "Aquarius" and the memorable line "This is the dawning of the age of Aquarius", brought the Aquarian Age concept to the attention of a huge worldwide audience. This New Age phenomenon is seen by some astrologers to be marked by the conjunction of the planet Uranus, ruler of the sign Aquarius, and the coming age, with Pluto, ruler of the masses, bringing radical change, in the 1960s. However, as the song relates, it is only considered by astrologers as the "dawning" or "cusp" of the Age, with the full strength of the Age not occurring until some time in the future.
