Astrology · history · collective cycles
Mundane astrology does not predict events like a newspaper forecast. It identifies periods whose planetary cycles resemble earlier moments of collective tension or change.
Mundane astrology studies nations, civilisations and collective movements rather than individuals. Its principal tools are the long cycles of Jupiter, Saturn, Uranus, Neptune and Pluto, whose orbits range from roughly 12 to 248 years.
When planets meet at the same zodiac degree, astrologers look for a new phase in their cycle. Saturn–Pluto conjunctions, roughly every 33 years, have been associated with periods of severe restructuring: 1914, 1947, 1982 and 2020.
Each phase from first quarter to opposition and last quarter is given a different symbolic quality. Saturn–Neptune cycles are often read as moments when collective ideals or illusions meet material limits.
André Barbault’s index sums the angular distances between five slow planets. A low index means planets are grouped and historical pressure is considered higher; a high index means they are dispersed and the period may be more expansive. It produces tonalities, not binary answers.
These examples concern analyses published before, or reconstructed from methods that could have been applied before, the events. They are historical case studies, not proof of causality.
Barbault’s writings in the 1960s identified 1973–74 as a period of high planetary concentration associated with a likely global economic crisis. The first oil shock began in October 1973, followed by worldwide recession in 1974.
Barbault’s work on Saturn–Neptune cycles described the 1989 opposition as a period in which rigid structures and closed ideologies could dissolve. The Berlin Wall fell on 9 November 1989.
Several mundane astrologers, including Barbault, had identified the late 2000s as a period of Saturn–Pluto friction and structural economic stress. Lehman Brothers collapsed in September 2008.
In L’Avenir du Monde (2011), Barbault described the Jupiter–Saturn–Pluto configuration in Capricorn as one of the most intense crisis patterns of the century and named 2020–2021 as a major collective crisis window. The WHO declared COVID-19 a pandemic on 11 March 2020.

A British astrologer and Jungian analyst. The Outer Planets and Their Cycles explores how Uranus, Neptune and Pluto symbolise collective revolutions and shifts in cultural paradigms.
It cannot predict the nature of an event. A crisis window does not reveal whether the pressure becomes a pandemic, war, financial collapse or natural disaster.
It cannot provide an exact date. “Around 2020–2021” is a window, not a day. Anyone claiming day-level certainty goes beyond what the method can honestly offer.
It does not establish causation. Planets do not cause wars or pandemics. At most, the method describes a correlation that some readers find meaningful.
Failed predictions also exist. Not every high-concentration cycle produces a major crisis, and not every crisis coincides with a low index. It is a method, not an oracle.
Without catastrophism or easy optimism, the planetary cycles of 2026–2030 deserve attention. Several rare configurations form close together, including what Barbault’s followers call the “Barbault Basket” in July 2026.
Jupiter, Neptune, Uranus and Pluto form six simultaneous aspects resembling a basket. In Barbault’s method, the relatively high concentration index suggests deep reorganisation rather than a single acute collapse: geopolitical balances, technology, social structures and economic models may all be reconsidered.
This remains a broad symbolic framework — intentionally humble, and not a prediction of a specific event.
Only marginally. Historians such as Nick Campion study it as history of ideas, while statistical approaches have been attempted by researchers such as Michel Gauquelin. It remains between cultural history, collective psychology and disputed proto-science.
Because his method identifies windows of collective pressure, not their precise form. A pandemic was one possible expression among war, financial crisis or environmental disaster.
It uses calculable cycles, historical archives and published reasoning. Whether its correlations are persuasive is debatable, but its method is different from an intuitive vision.
