Description of the Hellenistic Astrology Course

The purpose of the course is to provide a detailed introduction to the ancient Greco-Roman tradition of astrology known as Hellenistic astrology, which was practiced in the Mediterranean region from approximately the 1st century BC until the 7th century AD.

Hellenistic astrology is the original tradition of western astrology, and many of the techniques that are employed by modern astrologers today originated during the Hellenistic period. The purpose of the course is to learn about where those techniques came from, how they were originally used, and how they can be applied more effectively in practice today.

The course primarily focuses on natal astrology, and students will finish the course with a strong foundation in how to interpret birth charts in a systematic and effective manner.

Who is the course designed for, and what are the benefits?

The Hellenistic Astrology Course is primarily designed for students and practitioners of modern astrology who feel like they have gone as far as they can go with that approach and are looking for something more. Here are some considerations to help determine if the course is right for you:

  • If you want a more systematic way to interpret natal charts and determine specific information about both the nature and the course of a person’s life.
  • If you want to demystify the process of integrating the different components of a horoscope and learn how to achieve full chart synthesis.
  • If you are looking for a more accurate and consistent form of astrology that can be used to predict events. For example, how to tell when a person will hit a career peak.
  • If you want to know where astrology came from and what its technical and conceptual foundations are. For example, what is an aspect, or why does the 5th house signify children?

Most of all, the course is designed for those who want to become better astrologers, both by teaching you how to utilize the techniques you already know more effectively, as well as by introducing you to new techniques that can do things that you didn’t even know were possible.

What do you get when you sign up for the course?

Here are some of the things that you get access to immediately upon signing up for the course:

  • Over 90 hours of audio lectures with accompanying PowerPoint presentations on different facets of Hellenistic astrology. Click here for an example of a slide from one of the lectures.

  • Hundreds of chart examples, so that you can learn not just the theory underlying the techniques, but also how to actually apply them in practice.
  • Dozens of downloadable diagrams which help to explicate technical concepts. Here is an example of a diagram which illustrates the concepts of planetary enclosure and intervention.
  • Guided readings of translations of ancient astrological texts, with primers on basic vocabulary and concepts, in order to allow students to read more advanced material on their own.
  • Access to online discussion forums in which students can discuss concepts and techniques related to Hellenistic astrology with other students of the course

Synopsis of Each Part of the Course

Below you will find a brief synopsis of what is covered during each of the 10 parts of the course:

Part 1: The History of Hellenistic Astrology

The first part of the course provides a broad overview of the history of ancient astrology. In it we explore some of the historical undercurrents which fostered the development of Hellenistic astrology in Greco-Roman Egypt, and how developments in the earlier Mesopotamian and Egyptian astrological traditions led to the introduction of some of the basic technical doctrines, such as the zodiac and the twelve houses. Other topics covered include the mysterious origins of Hellenistic astrology, astrologers whose texts survived from this period, mystery schools present in the early tradition, and an overview of the ongoing efforts to recover the ancient traditions in modern times.

Part 2: The Philosophy of Hellenistic Astrology

The purpose of the second part of the course is to become familiar with the philosophical undercurrents that played a role in the development and practice of Hellenistic astrology. In particular we focus on debates surrounding the mechanism underlying astrology, as well as debates about fate and free-will, and the extent to which things were viewed as predetermined. This part of the course also features coverage of some of the major philosophical schools during this time period and their relationship with astrology, such as Platonism, Aristotelianism, Stoicism, Hermeticism, Neoplatonism, Gnosticism, and Skepticism.

Part 3: Basic Techniques and Concepts in Hellenistic Astrology

The Twelve PlacesIn the third part of the course you will learn the fundamental technical doctrines of Hellenistic astrology, through an overview of the core concepts of the system. This primarily involves an analysis of the ancient approach to dealing with the planets, signs, houses, and aspects.

This part of the course sets a foundation for a more precise approach to predictive astrology by introducing a number of basic interpretive principles and distinctions that are either missing from or are not entirely clear in modern astrology.

Part 4: The Domicile Lord of the Hour-Marker

In the fourth part of the course you’ll learn how to use the ruler of the Ascendant or “Hour-Marker” in order to determine information about the focus and purpose of a person’s life. This part of the course includes a review of the original conceptualization of the significations of each of the 12 houses.

Part 5: Rulers of the Twelve Places

In the fifth part of the course you will learn how to interpret the rulers of the twelve houses or “places” when they are in houses other than their own. For example, what it means when the ruler of the 7th is in the 10th, or when the ruler of the 11th is in the 9th, and so on.

Part 6: Conditions of Bonification and Maltreatment

In this part of the course you will learn about a special set of considerations for determining planetary condition, known as the conditions of bonification and maltreatment. These 7 conditions allow you to determine how a planet is functioning in a chart, and whether its significations are being affirmed and enhanced, or denied and corrupted.

Part 7: Lots or “Arabic Parts”

The purpose of the seventh part of the course is to introduce the technical concept known as Lots (kleroi), which are known in modern times as “Arabic Parts.” Lots are mathematical points that are used in a chart in order to study specific topics in a person’s life, and oftentimes they can be the key to understanding things that are otherwise unclear about a person’s life. In particular we will focus on the Lot of Fortune, and discuss the rationale for its calculation, as well as its meaning and uses in chart delineations.Triplicity rulers

Part 8: Triplicity Rulers of the Sect Light

In the eighth part of the course you will learn about the concept of rulership by trigon or triplicity, and I will show you how it is used within the context of a specific technique for determining the overall foundation of the nativity known as the triplicity rulers of the sect light. We will also introduce some of our first timing techniques, which are timing the activation of certain placements through planetary periods and ascensional times.

Part 9: Time-Lord Techniques: Annual Profections

The purpose of the ninth part of the course is to introduce the concept of time-lord techniques, and to focus on one technique in particular known as Annual Profections.

The premise of the Hellenistic time-lord techniques is that not all placements in a given natal chart are operating at their fullest potential at any given moment in time. Instead, there are specific periods in a native’s life when certain planets or sectors in the chart become activated, thus drawing out the latent potential of those natal placements.

Annual Profections are used in order to determine which planets will be activated in a native’s life in a given year, which allows astrologers to pinpoint the most important transits that will coincide with specific events. Profections can be used in order to determine what some of the primary themes are that will arise during the course of the year, as well as whether the year will tend to be experienced as more positive or more challenging.

Part 10: Advanced Time-lord Techniques: Zodiacal Releasing

In the tenth part of the course you will learn about a more advanced time-lord technique known as Zodiacal Releasing, which is one of the most impressive and powerful time-lord systems that has been recovered from the Hellenistic tradition to date.

Zodiacal Releasing lectureZodiacal Releasing divides a person’s life into chapters and paragraphs, as if the life was a book, and you were able to read the narrative of the native’s life like you would read the outline of a biography.

Each chapter in a native’s life begins with the activation of a specific planet as a time-lord, as well as the sign of the zodiac ruled by that planet.

Once all of the time-lord periods for a person’s life have been calculated, the technique can be used to identify periods of heightened importance and activity with respect to the native’s overall career and life direction, otherwise known as “peak periods.” The technique also provides information about which periods of the native’s life will tend to be experienced as the most subjectively positive or negative, career transitions, and other important life turning points.

When used in coordination with other techniques taught in the course, Zodiacal Releasing provides astrologers with a powerful method for determining information about the course of a native’s life, and becomes an indispensable tool for predicting the future.
