Mars in Gemini

Gemini opens a triangle that Ptolemy (Ashmand's 1822 translation) refuses to Mars outright. The signs of Gemini, Libra and Aquarius go to Saturn and Mercury, and Mars has no claim on them at all. Lilly 1659 still gives him degrees 11 to 20 of Gemini as his face and the last five degrees as his terms, minor allotments that keep a planet from counting as peregrine, the old word for having no standing in a sign.

Raphael's Guide of 1877 is one of the few books here to describe this exact pair. It gives a tall, big-boned frame with long arms and a character it calls rash, free, generous and aspiring. A frank catalog like that shows how the period wrote, and because the planet symbols in that scan are damaged, the order of its entries is partly inferred.

Mars is hot and dry in the old scheme while Gemini is hot and moist, which gives the pair one shared quality. Modern popular astrology tends to move the energy of Mars into talk, argument and many simultaneous projects. That mental reading is modern, and the older sources above give nothing so specific.
