Mundane Astrology

In this interview, Arwynne and Greek astrologer Thomas Gazis turn their attention to mundane astrology, the branch of astrology that studies world events and historical cycles.

Mundane Astrology

Thomas Gazis

Gazis explains that his approach has been shaped by influential thinkers like Dane Rudhyar and Richard Tarnas, while also drawing on his own decades of observation.

He describes the zodiac a “universal horoscope,” where planetary movements through the signs reflect shifts in collective human experience.

In particular, he emphasizes the significance of outer planets moving through the final quadrant of the zodiac—Capricorn, Aquarius and Pisces—the transpersonal or societal signs.

Pluto

Gazis shares his long-standing concern about the implications of Pluto’s movement through these signs.

While many astrologers have celebrated Pluto’s entry into Aquarius as a symbol of innovation and democratic progress, Gazis argues that the mythological underworld which is Pluto’s realm will be a powerful influence through the lens of Aquarius.

In this light, Pluto in Aquarius will intensify these darker collective dynamics, including technological warfare, social upheaval, and heightened global tension.

Planetary Resonance Cycles

A major theme of this discussion is the idea of planetary resonance cycles, particularly a roughly 500-year pattern in which several outer planets return to similar zodiacal positions.

Gazis notes striking parallels between current planetary placements and those present in the early 16th century, when European colonial expansion began reshaping the world.

He interprets this resonance as a signal that Europe may now be entering a period of cultural and geopolitical decline.

Historical Parallels

Throughout this conversation, Gazis illustrates how studying historical parallels in planetary cycles can help astrologers anticipate major collective developments—from global conflicts to shifting centers of cultural power.
