Definition: The word "aqua" appears in Greek mythology as a reference to water, specifically its intoxicating qualities, which led to the creation of humans and animals. The term was often used metaphorically to describe life or existence. Aquarius, however, is more commonly associated with a constellation of similar appearance, possibly the northern star (Aries) due to the Greek tradition associating it with Mars. The word "aqua" refers to the color, usually green, of water.
