Back to the Future. This is a comprehensive guide to classical astrology. Engaging with ancient and medieval astrology may seem outdated to some. After all, times have changed, and our entire worldview has little in common with the beliefs of our ancestors. Nevertheless, there has been a notable resurgence worldwide in recent times towards the earliest sources. This book allows readers to learn about and understand the techniques and practices of Greek and medieval astrology. The author goes far beyond what is commonly referred to as classical astrology. As a knowledgeable expert on the original texts, he particularly highlights the interpretation elements that have been forgotten or seem outdated. He succeeds in explaining even those methods that appear foreign to us from that time.
