On Astronomical Geomancy

Gerardus Cremonensis

Gerard of Cremona (Latin: Gerardus Cremonensis; c. 1114 – 1187) was an Italian translator of scientific books from Arabic into Latin. This is a short tract covering the twelve houses of astrology.

The New Word

Allen Upward

The term Scientology was first coined in this book by Allen Upward although the philosophy which Upward expounds in The New Word has nothing to do with any of the ideas of the latter-day Scientologists.
