What is Western
Sidereal Astrology?
Sidereal astrology, from the Latin sidus, (star) is the type of astrology that reckons celestial longitude from the positions of the stars rather than the vernal equinox. Western sidereal astrology is based on the Babylonian sidereal zodiac, the original zodiac. Western sidereal astrology is both new in the West and the revival of an ancient art.
Why Study
Western Sidereal?
Sidereal astrology is the pure unadulterated form of the art. It is the nexus of signs, aspects, planets and houses without a philosophical or psychological overlay. Sidereal astrology restores the crispness of the sign traits to their original venue. Sidereal interpretations are clear, concise and succinct.
