Hellenistic Astrology Explained

Hellenistic astrology (also known as Greek astrology) emerged in the Mediterranean region shortly after the death of Alexander the Great (323 BCE). It is an important phase in the history of astrology. Hellenistic astrology incorporated Babylonian techniques, Egyptian traditions, and mixed them with Greek philosophical concepts.

Origins of Hellenistic Astrology

Hellenistic astrology began in the Greek-influenced regions of the Mediterranean, especially in Egypt. The city of Alexandria in Egypt became a key center of scholarly activity, where many of the era's advancements in astronomy and astrology were made. The fusion of Babylonian mathematical techniques, Egyptian calendrical systems, and Greek natural philosophy created a distinctive new form of astrology. Hellenistic astrology also took influences from the philosophical schools of its time, including Stoicism and Hermeticism.

The Most Important Features of Hellenistic Astrology

The Birth Chart:
The birth chart (also called natal chart) is central to Hellenistic astrology. It maps the sky at the moment of birth. This chart is used to interpret various aspects of a person's character and destiny.

Planetary Influences:
Each planet is associated with specific a god or quality. Through their positions and relationships, various aspects of a person’s life and destiny can be inferred. The Greeks developed a system to classify the relationships between the planets, that is called “aspects”. An aspect is determined by calculating the distance between planets on the chart.
The most important aspects are:

• Conjunction (0°):
  A Conjunction occurs when two planets are in the same position on the birth chart. This is the most powerful aspect and signifies that the energies of the two planets amplify each other. A Conjunction may even occur between three or more planets. In this case, its effect is even more powerful.
• Sextile (60°) and Trine (120°):
  The Trine and Sextile aspects are considered to be harmonious aspects, in which the energies of the planets support each other. They are beneficial, but weaker than the conjunction.
• Square (90°):
  A Quartile aspect is generally considered to be a negative aspect in which the energies of the planets are at odds with each other, and may block or interfere with beneficial effects.
• Opposition (180°):
  An Opposition is the most powerful negative aspect between planets. It occurs when two planets are at opposite ends of the birth chart. This aspect usually has a negative impact on the character and faith of a person.
