Sky Chart and Artist Rendering of Aquarius

Origin:
One of the oldest constellations, dating back to the time of the Babylonians, Aquarius is the 12th sign in the modern zodiac. Aquarius is one of the 48 constellations described by Ptolemy in the Almagest (A.D. 140).

Information:
Aquarius, the Water Bearer, is a large important Fall constellation (northern latitudes).  Aquarius follows Capricornus by one month, culminating at 9 pm (or so) on November 1 (or so). Rather than the whole constellation resembling any single object, the individual asterisms of Aquarius define its pattern.  Aquarius is quite easy to find even though it is somewhat dispersed; it sits south of the Great Square of Pegasus and north of the bright star Fomalhaut in Pisces Austrinus - the brightest star in the southern Fall sky (for northern observers).

Mythology:
The whole area in the celestial sphere around Aquarius is associated with water or rain.  The Babylonians referred to the area as the "Sea" and populated it with several aquatic creatures:  Cetus the Whale, Capricornus the Sea Goat, Pisces the fishes, Eridanus the River, and Delphinus the Dolphin.  Aquarius is normally drawn as a man carrying a large water jug which is the source of life-giving water to the Sea. The Egyptian hieroglyph for water is the same as that used for Aquarius.
