Aquarius is a Fixed Sign

Aquarius is rued by Uranus

Aquarius is one of the oldest of the recognized constellations along the zodiac (the sun's apparent path). It was one of the 48 constellations listed by the 2nd century AD astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish and Eridanus the river.
The planet Neptune was discovered among the stars of Aquarius 154 years ago, in 1846, after its presence had been predicted and calculated from irregularities in the orbit of Uranus. Aquarius is also the radiant location for several meteor showers, including the Eta Aquarids of May, the North Delta Aquarids which peak on July 29, the South Delta Aquarids which peak on August 13, and the lesser Iota Aquarids, also of Augus.
Mythology

Aquarius is associated with water, rain, floods and fountains. In many ancient cultures, including Babylonian, Egyptian and Grecian, there was a god known as the 'Water Bearer' or 'Water Pourer.' Water is the bringer and sustainer of all life; therefore the force that made water rain down from the heavens was among the most revered by ancient peoples. Water also represents the collective unconsciousness - the sea of creation or consciousness.
Amphibious/Aquatic Gods
Anunnaki, Enki, Ea
Mesopotamia: associated with the eleventh sign, the eleventh month and the return of the deluge.
Babylonia: Aquarius represented an overflowing urn, and they associated this with the heavy rains which fell in their eleventh month.
Persian, Syrian and Turkish languages call Aquarius the Water Bucket.
Egypt: the setting of Aquarius in the Nile caused its flooding. In Egyptian mythology, he pours water into the Nile River at the season when the Nile normally overflows its banks, this brings the much needed water to the farmlands bordering that great river. The Egyptians saw the constellation as Hapi the god of the Nile. The water baptizer, guardian of the lower world.
The Arabs, dependent on the water of the rainy season, saw Aquarius as a bucket because their religion forbids them from showing pictures of any living form. The maiden's well / font pan of the abyss: Virgo's well, which Osiris used to birth his son (Virgo is Nephthys / Elder Isis: Herodias, mother of Salome - evening)
India: Aquarius is the first sign of the zodiac in India, where its patron saint is Varuna. This ancient god was originally the all-powerful lord of all the heavens and creator of the stars. But later he was looked on as just god of the water who looked down on the Earth through the thousand eyes of the stars. From his throat issued the seven streams of heaven. Varuna patrols his realm on a fabulous steed, half crocodile and half bird. So he is quite able to patrol both the air and the sea. Around 3000 BC it was possible to observe the full moon in this constellation every year around the time of the summer solstice, an event that was cause for celebration. This time represented the triumph of the moon god, Chandra, when he reached his maximum splendor and was drunk by the sun, Indra. Chandra was also identified with the magical drink of the gods, soma. With the sun crossing the solstice and the lengthening of daylight, the evil god of darkness and drought, Vritra represented by the constellation Hydra, was conquered. In India, the summer solstice corresponds with the return of the monsoon season and water to the land. Very similar to Egyptian tradition: Hydra/Vritra = Herod/Herut/Seth; monsoons at the summer solstice.
Peru: associated with the entrance of the sun into the constellation of the Mother of the Waters.
Christians of 17th Century: Christians of 17th Century: associated the constellation with St. John the Baptist
Greece: In antiquity, Hera's daughter Hebe, goddess of eternal youth, was cup bearer to the gods. Zeus replaced her with Ganymede after she spilled a flask of nectar. To further irritate Hera, Zeus immortalized his favorite server with a heavenly constellation.
Myth about Deucalion, the only man to survive the Great Flood. The story of this flood is very similar to the Judeo-Christian legend of Noah's Ark. It took place during the time named by Greek legend as the Iron Age.
Zeus had noticed this couple during his last visit to Earth. They lived alone in a simple hut. They had almost no food, and definitely had no material goods. Despite this, they fed Zeus, gave him shelter for the night and spoke kindly to him, even though they had no idea that he was a god. They were the last godly people on Earth, so Zeus allowed them to survive the flood. After it ended, he helped them to create a new race of men, which was supposed to be stronger and better. Deucalion is known as the 'Water Bearer' because he not only lived through the flood, but he helped to bring life to a new generation.
Greek Legend 1:
The water carrier represented by the zodiacal constellation Aquarius is Ganymede, a handsome Phrygian youth. Ganymede was the son of Tros, king of Troy (according to Lucian, he was also son of Dardanus). While tending his father's flocks on Mount Ida, Ganymede was spotted by Jupiter. The king of gods became enamored of the boy and flew down to the mountain in the form of a large bird, whisking Ganymede away to the heavens. Ever since, the boy has served as cupbearer to the gods.
The Cup-Bearer is male - Aquarius - John the Baptist
Greek Legend 2:
Ganymede was an exceptionally handsome, young prince of Troy. He was spotted by Zeus, who immediately decided that he would make a perfect cup-bearer. The story then differs - one version telling how Zeus sent his pet eagle, Aquila to carry Ganymede to Olympus, another that it was Zeus, himself, disguised as an eagle, who swept up the youth and carried him to the home of the gods. In either case, once Ganymede arrived, he had to contend with the wrath of Hera, wife of Zeus. Hera likewise had Zagreus murdered. Is Hera Isis?
She was annoyed on two counts - firstly, that her husband should have such strong feelings for a mere boy and, secondly, that Ganymede was to occupy the favored position previously held by her own daughter Hebe, goddess of youth. But Zeus was not to be thwarted and Ganymede, often riding on Aquila and always carrying the golden cup, accompanied the great god on his travels, impressing him with his kindness. This was made manifest when, realizing how in need of water the people on earth were, he pleaded with Zeus to be allowed to help them and was given permission to send down rain. Eventually he was glorified as Aquarius, god of rain, and placed amongst the stars.
Greek Legend 3:
Zeus was the Water Bearer. Although he was the god of many things, one of his most important roles was as the god of storms. The constellation Aquarius could have originally been representative of Zeus as the Water Bearer.
