An Introduction to the Tetrabiblos (The ancient series Book 1)

Imagine that you are sitting in ancient Greece, surrounded by fellow Astrology students. When you look down, you notice that you are holding two text books. The first one is the "Tetrabiblos," written by the great thinker Claudius Ptolemy. The second is this very book!

"An Introduction to the Tetrabiblos" is a marvelous "textbook" written by the philosopher Porphyry of Tyre. Within these now digital pages, Porphyry sets out to clarify certain concepts that Ptolemy wrote about years earlier.

Porphyry's work has been rendered into clear and eloquent English by Andrea L. Gehrz. Drawing on her many years of experience in the field of Sign Language Interpreting, Gehrz has brought this text back to life!

Any student of modern or ancient Astrology will surely be enthralled with what they find within these ancient-yet-digital pages!
