Learning Astrology

The learning path

Go in order. Each step builds on the last, and it's fine to spend weeks on one. The most useful habit is to check everything you learn against your own chart and the charts of people you know well.

1. Learn the alphabet

   Astrology has four building blocks: the planets (what), the signs (how), the houses (where in life) and the aspects (how planets talk to each other). Learn the meaning of each, and the 12 symbols.

   • Cheat sheetMy study notes with keywords for every planet, sign, aspect and house
   • TipMake flashcards of the glyphs and keywords until you can read them without thinking.

2. Cast your own birth chart

   You need your birth date, time (as exact as possible) and place. Free software draws the chart for you, so there's no need to calculate by hand.

   • Free toolAstro-Seek, with charts, transits and many calculators
   • TipYour birth certificate usually has the time. If not, ask family or the hospital.

3. Read a chart piece by piece

   Start with the "big three": Sun, Moon and Ascendant (rising sign). Then go planet by planet: its sign, its house, its aspects. Write out a sentence for each and see if it sounds like the person.

   • BookAspects in Astrology by Sue Tompkins
   • PracticeRead the charts of 5–10 people you know well, and of famous people with known birth times.

4. Put it together: synthesis

   The hard part is weighing everything at once: which planets are strongest, what themes repeat, and where they contradict each other. This is where astrologers really improve.

   • BookThe Only Way to Learn Astrology, Vol. 2, which focuses on putting a chart together
   • FreeAstro-Databank has thousands of famous birth charts with rated birth-time accuracy

5. Learn timing: transits and progressions

   Transits compare where the planets are now to your birth chart. Progressions and solar returns are other timing methods. Keep a journal of your transits and what actually happens.

   • NotesJupiter & Saturn life cycles, the big returns at ages 12, 24, 30, 36 and beyond
   • Free toolThe transit and solar return calculators on Astro-Seek or astro.com

6. Go back to the source: traditional astrology

   Modern astrology is only about 100 years old. Reading the ancient and medieval techniques, such as sect, dignities, profections and lots, deepens everything. Many of the old texts are free (see Books).

7. Keep learning with others

   Listen, discuss, and read charts for friends. Explaining a chart out loud is the fastest way to find what you don't understand yet.

A short history

Astrology is one of the oldest continuous intellectual traditions in the world. It passed between Babylon, Egypt, Greece, India, Persia, the Islamic world and Europe, and each culture reshaped it.

1. c. 2000–1000 BCE

   Mesopotamian omens

   Babylonian priests watch the sky for signs about the king and the kingdom. Thousands of omens are collected in the series Enūma Anu Enlil.

2. c. 500–400 BCE

   The zodiac is born

   Babylonian astronomers divide the sky into 12 equal signs of 30°. The oldest known personal horoscope dates from about 410 BCE.

3. 2nd–1st c. BCE

   Hellenistic synthesis

   In Ptolemaic Egypt, Babylonian astronomy meets Greek philosophy and Egyptian tradition. The birth-chart system of houses, aspects and the Ascendant takes shape, credited to texts attributed to Hermes Trismegistus.

4. 1st c. CE

   Manilius & Dorotheus

   The Roman poet Manilius writes Astronomica, a poem about astrology. Dorotheus of Sidon writes a verse textbook that later becomes hugely influential in Arabic translation.

5. 2nd c. CE

   Ptolemy & Valens

   Claudius Ptolemy writes the Tetrabiblos, explaining astrology in terms of natural philosophy. Vettius Valens writes the Anthology, full of practical example charts.

6. c. 2nd–6th c. CE

   Astrology reaches India

   Greek astrology is translated in the Yavanajātaka and blends with Indian tradition, developing into Jyotiṣa (Vedic astrology).

7. 8th–10th c.

   The Islamic golden age

   In Baghdad, scholars like Māshā'allāh and Abū Ma'shar translate and expand Greek, Persian and Indian works, adding refinements to horary, electional and historical astrology.

8. 12th–16th c.

   Medieval & Renaissance Europe

   Arabic texts are translated into Latin. Astrology is taught at universities alongside medicine and astronomy, and is used by doctors and royal courts.

9. 1647

   William Lilly

   Lilly publishes Christian Astrology, the first major astrology textbook in English. It remains the classic text on horary astrology.

10. 17th–18th c.

    Decline

    With the Scientific Revolution, astrology loses its place in universities and among the educated elite. It survives in almanacs and folk practice.

11. Late 1800s

    The modern revival

    Through the Theosophical movement, Alan Leo popularizes a simplified, character-focused astrology, which becomes the basis of modern Western astrology.

12. 1930

    Sun-sign columns

    R. H. Naylor's horoscope for Princess Margaret in the Sunday Express leads to the first regular newspaper sun-sign columns.

13. 20th c.

    Psychological astrology

    Influenced by Carl Jung, astrologers like Dane Rudhyar and Liz Greene recast the chart as a map of personality and personal growth.

14. 1990s–today

    Traditional revival & the internet

    Projects like Project Hindsight translate ancient texts, sparking renewed interest in Hellenistic and medieval methods. Free software, apps and podcasts bring astrology to millions.
