The Water Bearer. Aquarius is part of the Zodiac. Aquarius is a rather faint constellation, which would not be famous if it weren't part of the Zodiac. Aquarius, as its name suggests, is universally associated with water. Aquarius is the "watery" part of the sky known to the Babylonians as "the sea". In most cultures, it is drawn as a man pouring water from a bucket. This may arise from the fact that the Sun enters Aquarius in early winter when the rainy season begins in many parts of the world.
