Famous Astrologers – Part 1

Do you know who are the top astrologers that have ever lived? In this blog we introduce you to the greatest astrologers, either living or dead, some of them might be more famous than others, but one thing that they all have in common is the love of the heavens and trying to interpret them.

Some astrologers class themselves as scientists, and some are little more than charlatans, in this blog we try to sort out the wheat from the chaff.

Galileo Galilei

Galileo Galilei is most well known simply as Galileo. He was a physicist who hailed from Italy, but he also excelled in engineering, mathematics, philosophy as well as astronomy. He lived during the Renaissance Period and contributed to many of the periods’ great developments, including improvements to the telescope, which enabled him to expand on his astrological observations. Galileo has been named as the father of modern physics and the father of modern science.

Some of his greatest astrological discoveries have included the four largest satellites of Jupiter, the phases of Venus and the observation of Saturn’s rings. Galileo’s biggest achievements came in applied science and technology, he studied velocity, gravity, inertia and projectile motion.


A Greco-Egyptian, Ptolemy was primarily a writer who excelled in mathematics, and, as his interest in the stars grew, he became a keen astrologer. Living in the ancient city of Alexandria, he was actually a Roman citizen although his writings were in Greek.

One of his most famous writings is known as the Almagest, which is an astronomical and mathematical theory of the movements of the stars and their planetary paths. This writing is a most important reference source about Greek astronomy at the time, and it is also most valuable as a note of the Greek Mathematician Hipparchus’ work, which has now been lost. Hipparchus mostly wrote about trigonometry, but modern-day mathematicians have to refer to Ptolemy to understand what he wrote.

Aleister Crowley

Crowley was a British writer mostly interested in the occult, and he is most famous today for his writings on this topic. He was a founder member of several occult institutions and organizations, including Argenteum Astrum, Ordo Templi Orientis and Golden Dawn.

His interests continued into astrology and he also was a ceremonial magician. Crowley founded his own religion called Thelema, he proclaimed himself as its prophet and was tasked to guide his followers into the Aeon of Horus. In the early 1900’s he was declared as the most wicked man in the world by the popular press of England and brandished a Satanist. Perhaps his lifestyle of drugs, social critic and as renowned bisexual did not endear him to the conservative people of England at the time.

Although there was a strong rumor that he was engaged at Cambridge University to become a British spy, this has never been proven. It certainly is a controversial claim, as he spent most of WWI in America where he campaigned energetically for the German war effort against his native country.

Crowley is a world away from our first two astrologers, but has to be named in our list of the world’s most famous astrologers due to his notoriety. In part two of our blog we look at other amazing characters in the field of astrology.
