This is a revised and expanded edition uniting both volumes of the "Mysteries of Medieval Astrology". Astrology was always meant to be a powerful predictive tool. Still, in recent years, it has drifted towards pseudo-psychological interpretations. Many modern astrologers have become so enamored with trendy esoteric beliefs that they've lost sight of astrology's true potential for precise predictions. It's time to reclaim astrology's original purpose-and this book will show you how. This comprehensive textbook takes you on a step-by-step journey from beginner to expert in predictive astrology. Each chapter is meticulously crafted to progressively build your skills, ensuring you gain a deep and practical understanding of making verifiable and accurate forecasts. You will learn to confidently predict exact dates and details of events using time-tested techniques from Renaissance astrology.
