planetary movements and world historical trends and events
for the use of historians and astrologers

There are identifiable cycles of change in history and a clear relationship between the motions of slower-moving planets and historical events and trendsThis book demonstrates this.

However, current historical practice and received wisdom disagree.


Events and concrete changes in history often have their beginnings in the ideas, experiments and initiatives of people, occurring before the actual event. Astrology can identify the times when formative ideas and new trends take shape, and thus shape subsequent history.

Human free-will certainly does play an enormous role in historical events, yet it operates within the context of the nature of the times and the quirks or constraints of the 'energy-weather' at any time.

An astrological study of history isn't about 'fate' or determinism in history; instead it reveals an interaction between changing energy-conditions and our human responses to evolving situations. A study of astrological history shows the many ways that this process works. It describes the inner nature of the times, and the threads and tides underlying events.

The Historical Ephemeris is a reference work which can transform

your understanding of human history

and the deeper psychological processes lying behind it.



May this journey into the essence of historical time and change contribute to a wider and deeper understanding of world history. This is important, since we now live in a century of choice. Big choice.

This is the consequence not necessarily of astrological cycles or influences: it is a consequence of humanity's accumulated actions and choices to this day, within the context of those astrological influences. Over time we have made the choices we've made, and today the scope of our choice is accentuated enormously since the accumulated consequences are now with us more than ever before.


A note to astrologers without historical training: remember that it is too easy to cherry-pick and interpret events to fit one's astrological theories and predilections. A lot of consideration and understanding of historical events is needed. The best way to do this is to study the history first, picking events considered to be significant historically, and only then to put it alongside the astrological data. Astrological motions don't always create the outcomes that astrological theory expects; on a Mars conjunction to Pluto, it's just as likely that peace or war could break out - the 'god of war' has many tricks up his sleeves.

A note to historians with no astrological training: conventional history predicates that there is no inherent system or pattern to history. Therefore positing a 'theory of history' involving astrology can only be bunkum. I suggest that this standpoint will one day change, and astrological theory will prove useful in informing a new understanding of world historical processes. This particularly concerns the largely unconscious psychological dynamics that hide behind historical events.

A note to astrologer-historians. You will enjoy this ephemeris. There's a lot here. Good luck!


About the making of the ephemeris

This research was done in 1988-93 (in UK, USA and New Zealand), with slight revisions in 1999 and 2012.

Heartfelt acknowledgements to the following people for their assistance and encouragement in the calculation and compiling of this work:

  • the late Neil Michelson, San Diego USA, for starting me off with valuable data in 1988;

  • Rob Hand of Astrolabe, Cape Cod USA, for providing computing facilities (using the AstroAnalyst program), and for his ideas and encouragement (1988-89);

  • Nancy Lavoie of Massachussetts, USA, for her help and encouragement;

  • the late Steve Hill in New Zealand for facilities and for understanding this work;

  • Sig Lonegren, once of Vermont USA, now in Glastonbury, England, a dowser and prehistorian who practically encouraged this astrologer in his work.

May this Historical Ephemeris give you endless hours of fascination!

The Historical Ephemeris
by Palden Jenkins
Astro-historical tables for 2,500 years

The material contained in this ephemeris leads toward a new theory and understanding of history

Part One

5. The Next Seventy Years


Uranus-Neptune-Pluto conjunction, 578-575
In a sense the beginning of recorded history.
Before that, archaeology.
This is why this ephemeris starts at 600
