The corresponding month in the Babylonian calendar is Arax Šabaṭu, "the destroying month", also called arax arrat zunne, "month of the curse of rains", associated with the Great Flood. It is dedicated to Ramman, the storm god. The zodiacal sign of this month was called GU = Assyrian qâ, the name of a dry-measure. This was associated with Hebrew kad, "pitcher, jar", presumably in reference to the urn of Aquarius. The name Aquarius of this sign is of occidental origin, while Babylonian astrology symbolizes it with a simple amphora, in reference to the apsû (diluvial) region of the sky.
The astrological symbol for Aquarius is said to represent waves or ripples of water.
