As with Venus, the sign for Mars is recognized everywhere as the male. Named for the Roman god of war, especially in the sign of Aries, it stands for dynamic defensive action, emotional passion, and creative drive. Once the ruler of both fire-sign Aries (March 21-April 20) and watery Scorpio, the latter sign was reassigned to Pluto. Depending which sun-sign it is in, Mars shows how the native expresses his energy and where strife may be found in the chart. Its energy is needed for any kind of action and achievement; yet stress and tension can be byproducts.
