The enigmatic jug of Aquarius represents not just a container but a mystery laden with various interpretations and symbolic significances. As one of the air signs, Aquarius is often associated with the flow of ideas, knowledge, and humanitarianism. The jug, therefore, is not just a physical object but a vessel through which the wisdom of the universe is transferred to humanity. Astrologers have long debated and speculated about its contents. Some suggest that it contains the waters of knowledge, representing Aquarius’s role as the bearer of enlightenment and insight. The “water” is not literal but symbolic, implying a flow of spiritual or intellectual nourishment that Aquarius dispenses to the world.

Others interpret the jug’s contents as a kind of cosmic energy or ether, an abstract but potent force that catalyzes change and progress. This aligns with Aquarius’s reputation as a sign of innovation, originality, and sometimes, revolution. The pouring out of this ethereal substance symbolizes the dissemination of revolutionary ideas and energies that challenge the status quo and catalyze humanity’s evolution.

Moreover, some astrological traditions view the jug as containing nothing less than the essence of life itself, a kind of divine nectar or amrita. In these interpretations, Aquarius becomes a divine conduit, channeling the essence of existence from the universe to the Earth, emphasizing the sign’s role in sustaining life and bringing further progress through its insights and ideas.

The imagery is rich with philosophical and existential layers, suggesting that what pours from the jug is limitless—perhaps the infinite potential of the universe itself. Aquarius’ vessel distributes its universal gifts, ensuring  enlightenment reaches all corners of the human experience.

Thus, while the precise nature of what’s in the jug might remain a puzzle, its symbolic importance is clear. It represents Aquarius’s connection to the broader aspects of life, acting as a medium through which the vast wisdom of the stars is made accessible to humanity.

According to Mythic Astrology: Internalizing the Planetary Powers:

“We are more inclined, in this technological era, to think of Aquarian waters as electricity or cosmic energy.”

Interpretations surrounding Aquarius, known as the Waterbearer, contain a multitude of symbolic representations. The term “Waterbearer” itself, derived from the Latin word “aqua,” directly translates to “water bearer,” and highlights the sign’s essential nature of carrying and dispensing what is often perceived as the essence of life: water. In mythology and astrology, water is a powerful symbol. It represents fluidity, intuition, and the unconscious, and in the case of Aquarius, it takes on a more expansive meaning. Aquarius is often seen as a distributor of knowledge and a harbinger of change, reflecting its elemental association with the air, despite its watery name.

The Egyptian mythological interpretation of Aquarius associates it with the cause of the Nile’s annual flood. It portrays Aquarius as a life-giver, a renewer of the earth through the vital waters, symbolizing fertility, abundance, and the natural cycle of renewal.

Another description describes Aquarius as “the pourer forth of water” and its connection to the Great Fish (Pisces). Here, the water from Aquarius’s jug flows into the mouth of Pisces, creating a continuum of spiritual and existential nourishment. Its imagery suggests a universal cycle where Aquarius’s insights and revolutionary energies are integrated into the collective unconscious, represented by Pisces.

Early religious interpretations adding the dimension of the water being “full of vision” and symbolizing “renewed power” point to the transformative potential of Aquarius. The act of pouring water on the heads of the people can be seen as an act of baptism or enlightenment, where knowledge and spiritual awakening are bestowed upon humanity.

These diverse interpretations of Aquarius’s jug reflect the sign’s complexity and its pivotal role in astrology. As with the two fishes of Pisces, which encapsulate the dual nature of reality, the meanings surrounding Aquarius’s water-bearing function illustrate a deeper connection between the heaven’s above and the earthly realm, highlighting the sign’s position as a conduit for cosmic wisdom and change.

Most agree that Aquarius is pouring forth knowledge and new revelations of a celestial kind. Frequently, the sign is also imagined as a giant male figure, pouring down the water onto the Earth as visualized by Clifford Bias, relating the water as being cool and clear. Yet, the most accurate portrayal is found in the Cosmic Apprentice: Dispatches from the Edges of Science, which describes the spirit of Science, an Aquarius subject, in a rather Waterbearing way:

The Spirit of Science is open democratic. It flows like water. It is even, you might say, evinced by life itself, what we call life is really a form of water, activated and animated not by a divine principle but the energetic cosmos around it.

Finally, Liz Greene has this to say about the Aquarian and his Waterbearer nature.

In Egyptian myth, the benign god Hapi carried on his shoulders a vast jug from which he poured out waters from the Nile, thus imitating the great annual inundation on which crops depended. The Greeks envisaged him as the beautiful Ganymede, beloved of Zeus and cup-bearer of the gods. But the mythic figure who best epitomizes Aquarius, last of the air signs, is a bearer of fire rather than water. The Greeks called him Prometheus, which means “he who has foresight”; he stole Zeus’ divine flame and gave it to human beings so that they could learn to live as civilized creatures. The magical substance which the water-bearer carries, whether fire, water or the elixir of life, is not easy to define. But the myth of Prometheus suggests that it is the power of inspired knowledge which Aquarius pours forth – knowledge of harnessing the forces of nature to create an efficiently functioning world, in which everyone and everything has its role and contributes to the good of the whole.
