Life & Context
Born in Nola in 1548, Bruno entered the Dominican Order as a young man. Brilliant, restless, and fiercely independent, he studied theology, philosophy, and astronomy but quickly grew disillusioned with rigid orthodoxy. He left the order, traveling through Europe as a wandering philosopher. His writings combined Copernican astronomy, Hermetic mysticism, and bold reinterpretations of Christian theology.
Bruno’s cosmology went beyond Copernicus: he declared that the universe was infinite, with countless suns and planets, and that God’s presence filled all of it. For him, studying the stars was not heresy but a path to understanding the divine.
Astrology, Scripture, and the Cosmos
Bruno embraced astrology as part of a universal wisdom tradition. Like earlier mystics, he saw biblical symbolism as astrological allegory. He believed:
- The twelve apostles reflected the twelve signs of the zodiac.
- The Book of Revelation was a cosmic drama of stars, beasts, and celestial cycles.
- The sun was not only a physical light but a spiritual image of Christ, whose light extends to all worlds.
“There are countless suns and countless earths all rotating around their suns, in exactly the same way as the seven planets of our system.”
— Giordano Bruno, On the Infinite Universe and Worlds (1584)
For Bruno, astrology was not fortune-telling but a sacred science of correspondences — reading the divine order in both Scripture and the heavens.
Conflict with the Church
Bruno’s radical views — reincarnation, infinite worlds, allegorical interpretations of Scripture, and the blending of astrology with Christianity — alarmed Catholic authorities. After years of wandering through France, England, and Germany, he was eventually arrested by the Inquisition in Venice and extradited to Rome. After seven years of trial, he was condemned for heresy and burned at the stake in 1600.
“Perhaps you, my judges, pronounce this sentence against me with greater fear than I receive it.”

A Vision of Infinite Worlds
Bruno’s most enduring legacy was his vision of an infinite cosmos. While Scripture spoke of God’s heavens, Bruno expanded the concept: God’s creation could not be limited to one world. The same divine order that the Bible describes symbolically was, for Bruno, spread across infinite stars and planets.
“The universe is then one, infinite, immobile… It is not capable of being comprehended and therefore is endless and limitless.”
— On the Infinite Universe and Worlds (1584)
Legacy & Influence
Giordano Bruno became a martyr for free thought and cosmic religion. Though condemned in his time, his ideas anticipated modern astronomy and inspired later mystics, philosophers, and scientists. Today he stands as a symbol of intellectual courage — and for our Astrology and the Bible series, he represents a bridge between biblical symbolism and a new, infinite vision of God’s cosmos.
