What brought you to astrology?
At first it was skepticism about the subject. I noticed someone at work was using it to day trade, and I told him that was nonsense. He told me I was ignorant and suggested reading “Horoscope Symbols” by Robert Hand. Doing that put me on the path.
Who did you study astrology with?
Soon after getting interested in astrology, I became enamored with traditional practices, in particular Robert Zoller’s approach to medieval astrology in conjunction with philosophy. After studying with him, I wanted to go deeper into traditional astrology and older (and older) sources, so I eventually ended up learning from Robert Schmidt at Project Hindsight.
What is your specialty, or focus?
“Hellenistic astrology” would probably describe my focus. Currently I’ve been studying Valens more deeply, working with some of the more unusual techniques he describes.
What are your top 3 favorite astrology books?
So many to choose from! I’d have to go with “The Judgment of Nativities” by al-Khayyat, which is a solid traditional natal textbook. The “On Reception” by Mashallah, which is what helped me finally under horary. And finally, Robert Schmidt’s reconstruction of Antiochus “Definitions and Foundations”, which is an attempt to define the basic principles.
If you could have dinner with any historical astrologer, who would it be?
Probably Valens at the moment, if only to interrogate him! He really leaves out a lot of detail and I’m very curious what he left out. Bonatti would be my alternate, if only to hear how catty he was.
Is there a planet, sign, or aspect you’ve been exploring lately that represents an archetype or energy that feels important to you right now?
Thinking how the Great Conjunction of Jupiter and Saturn sets the current times, and then continues to permutate with their following transits.
Are there any additional comments you would like to make about your lecture?
I think it will be great to show how amazing profections can be. To show how such a simple technique can develop into much (perhaps too much) complexity and very quickly. And how very useful it can be, in itself and as a paradigm for all other time lords.

Gabe Rosas has been a dedicated student of study of traditional astrological systems for more than twenty years. His journey began with the medieval astrology course developed by renowned astrologer Robert Zoller, which provided a solid grounding in the interpretive methods and philosophical underpinnings of pre-modern astrology. Seeking to deepen his knowledge and engage with the roots of the tradition, Gabe later became a student of Robert Schmidt at Project Hindsight, a pivotal initiative that played a significant role in translating, recovering, and revitalizing ancient Hellenistic astrological texts for a modern audience. He is dedicated to making the rich legacy of traditional astrology accessible and meaningful for people living in the present day. His approach highlights the enduring relevance of ancient techniques and encourages a contemplative engagement with the complexities of planetary influence, inviting individuals to consider how the rhythms of the cosmos can illuminate the patterns and turning points within their own lives.
