Solar Biology

The next time someone asks you "what's your sign" as an icebreaker, remember Mr. Hiram E. Butler. Butler put forward a radically simplified version of astrology during the 19th century. Up until then, astrologers had laboriously plotted out the configuration of the planets, including exact angles between planets, houses (which are specific to a geographic location and time), ascending nodes, descending nodes, rising signs, and so on. And this is still what a professional astrologer will base his or her advice on. Whether or not you believe, one has to admit that this not the easiest method of divination ever invented. One can't just learn this on a whim.

However, the vernacular astrology, with everyone divided into twelve pigeonholes based on their natal sun sign, can be traced back to Mr. Butler, and particularly this book, "Solar Biology", first published in 1887. Butler actually divided everyone into 144 pigeonholes, based on their natal sun and moon signs. The planets are also used, but only the sign they occupy is important; the angles between them are ignored. This makes it easy to create a horoscope, as the time and place of birth are no longer required. The tricky computation of the rising signs and houses is skipped. You just look up the positions in any ephemeris, then read the matching page in this book. The result is a system so simple, practically anyone can do it.
