The Anthology of Vettius Valens

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.

Introduction to Hellenistic Astrology

Interpreting the Rulers of the Houses

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.
