|War (1924) by Otto Dix, who had Mars in Libra and turned his experience of battle into art|
For example, Mars, the god of war is said to be in rulership in Aries and in Scorpio (supposedly good placements), in detriment in Libra and in Taurus (supposedly bad placements). He is exalted in Capricorn and in fall in Cancer.
However, the more I study planets in detriment and in fall, the more I think we need to see them simply as special. Currently, Mars is spending a long time in Libra. Mars is aggression, courage, force, battle, libido. Libra seeks harmony in our social interactions. Libra is often about an unspoken connection between individuals or between one person and wider society. Libra also creates harmony by turning war into art.
All of these people have Mars in Libra in their natal charts. As you will read, there's potential for good and bad in this placement.
