Joseph is a proud practitioner of the Hellenistic Astrology.
The Hellenistic Era was from 3rd century BCE to the 7th century AD
in Greece, Egypt & Rome.
All subsequent astrology, of both the West and the East (Indian / Vedic astrology) have their point of origin in this one place, wherein the Genesis of astrology is known to have occurred.
The first phase of astrology's existence was hidden from the public. This was in the time of three of the greatest ancient Greek thinkers: Plato, Aristotle & Eudoxus. This was the 5th century BC, and their material was largely generated in the shadow of the ancient Egyptians.
By three centuries into the future, astrology had been born, and was used especially by royalty.
You may wonder about the future of astrology, now that we have recently recovered what the ancients were up to. This is perhaps the first time in nearly 2000 years that someone has grasped the original material. All the ancient texts have been translated into English.
