Hot (religion, spiritualism, and occult)
The signs are numbered from 1 to 12 according to their order in the zodiac (e.g., from Aries, 1, to Pisces, 12). Hot and cold made up one of the sets of categories utilized in premodern physics, and the ancients classified all odd-numbered signs (all fire and air signs) as hot. Traditionally, the Sun and Mars were also considered to be hot, while Jupiter and Venus were regarded as warm (an intermediate category). The terms hot and cold are rarely used in modern astrology.
