Papus (1865-1916), lived during a period when an interest in mystery traditions peaked in Europe. This work is a translation of his resulting writings with an introduction that places Papus in a historical perspective. It also includes explanatory notes and supplementary material

By borrowing from Burgoyne and the Continental astrological tradition, Papus produced a work that provides fresh insights to the English speaking astrological tradition. Lehman's introduction places Papus in an historical perspective and explains his influence in late 19th and early 20th century France. 

In translating this work from the French, she has given English speaking students of astrology and the Western Mystery Tradition an important source work.
