The Anthology of Vettius Valens
Vettius Valens was an astrologer who lived in Alexandria, Egypt in the middle of the second century. His Anthology is a collection of instructional texts on astrology that he wrote for his students in Greek.
The Anthology is the single most important surviving source for understanding what the practice of astrology was like in ancient times, because Valens included more than one hundred examples in order to demonstrate how birth charts were interpreted in antiquity. This publication marks the first time that the entirety of the Anthology has ever been translated into English.
Available for purchase now: The Anthology of Vettius Valens.
An Introduction to Hellenistic Astrology
In this 100-minute lecture I discuss how recent efforts to translate ancient Greek and Latin astrological texts have resulted in the recovery of dozens of important techniques and concepts, which have the potential to enhance and improve the practice of astrology today.
This talk will provide an introduction to ancient astrology, and demonstrate that by looking into the past, we can create a better astrology for the future.
Interpreting the Rulers of the Houses
In this 70-minute lecture I present a simple but effective method for interpreting what it means when the ruler of one house is in another house in a birth chart. For example, what does it mean when the ruler of the 11th house is in the 9th house, or when the ruler of the 7th is in the 10th?
In the second half of the lecture I demonstrate how to determine when these placements will become activated in specific years in a person’s life by using a timing technique called annual profections.
Timing Peaks and Transitions in Your Career and Life Direction
An 81-minute lecture on how to time peaks and transitions in your career and life direction using the Hellenistic time-lord technique called zodiacal releasing.
Focuses in particular on the charts of politicians and celebrities, and identifying periods of eminence.
Timing Peaks in Your Love Life: ZR From the Lot of Eros
A 2.5-hour workshop on how to use the zodiacal releasing time-lord technique to time peaks and transitions in a person’s love life and relationships.
Demonstrates how zodiacal releasing can be modified to study relationships by starting from the Lot of Eros, and the specific calculation preserved in the work of the 4th century astrologer Paulus of Alexandria.
