Mars in Pisces

Lilly 1659 puts Mars in charge of the watery group by day and by night, and Pisces is the last of its three signs. He also places the last ten degrees of the sign as the face of Mars and degrees 21 to 26 as terms, so late Pisces collects several small allotments at once. All of this happens in a sign that belongs, as a house, to Jupiter.

Ptolemy, in Ashmand's 1822 translation, handles the same triangle differently. He gives Cancer, Scorpio and Pisces to the Moon by night and Venus by day, together with Mars, who holds his place only through Scorpio. Where Lilly makes Mars sole governor, Ptolemy makes him one of three.

Mars is hot and dry and Pisces cold and moist, opposite on both counts, and no source here gives a character for the pair. Modern popular astrology often describes energy that rises and fades with mood or goes toward quiet help for others. Treat that as the modern layer, since the older books are silent on it.
