The twelfth century saw a large number of Arabic texts on natural philosophy translated into Latin for the first time. Many of these texts were astrological, and had originally been translated into Arabic in the eighth and ninth centuries, shortly after the rise of Islam, from original Greek, Persian and Indian sources. Knowledge of astrology in Western Europe prior to the twelfth century was limited, although the need for Christians to calculate the date of Easter meant that an understanding of solar and lunar cycles was important, leading to the development of the science of computus, taught in secular cathedral schools, which were the main centres of learning in England in the twelfth century. One school with a reputation for scientific learning was the cathedral school at Hereford, and this research focuses on a text of a teacher there, Roger of Hereford, who compiled the newly-translated Arabic material on astrology into a single book, Judicial Astrology. – By the thirteenth century, astrology had become an established part of the curriculum taught in newly-established universities across Europe, and included studying works by Arabic astrologers that had been translated into Latin. What has not been researched in detail until now, though, is how astrology was taught in that century between the translation of Arabic texts and its establishment as part of the quadrivium in universities, and a detailed examination of Roger’s seminal book. – This thesis examines his Judicial Astrology in detail, analysing the astrological techniques used, identifying Roger’s sources, and looking at his teaching methods. – This thesis sets the context within which astrological texts were translated, and provides an analysis of every extant manuscript of Judicial Astrology. The conclusion examines Roger’s claim that he compiled the first astrology book in England, and asks whether it still stands as a usable text today.

Roger of Hereford’s Judicial Astrology

England’s First Astrology Book: Roger of Hereford’s Judicial Astrology

The twelfth century saw a huge renaissance of astrology in Christian Europe, as numerous astrological texts were translated from Arabic into Latin. An English scholar called Roger, teaching in the cathedral school at Hereford, made use of these new translations to produce a textbook of horary astrology for his students, creating the first astrology textbook in England: Judicial Astrology. Roger’s seminal textbook contains many techniques that are not well-known among astrologers today, even among traditional astrologers, but are fascinating and worth trying out in your own astrology practice.

Roger was teaching in England but, like all scholars of his time, wrote his textbook in Latin, and until now it has never been translated, meaning Roger’s innovative work has been largely hidden for over eight centuries. This book addresses that gap; it’s the result of nearly a decade of research that Chris Mitchell did for his PhD, unearthing the original manuscripts, transcribing the scrawling and heavily abbreviated handwriting, and translating the often confusing text into English. However, that PhD did not provide a full translation but focused on academic aspects of the text; this book is aimed not at academics, but at astrologers.

This books aims to give Roger a voice – a modern voice, where instead of talking to you in Latin or archaic English, he can go through his techniques and explain them in modern English. Roger’s original text doesn’t have many worked examples, although as a teacher Roger probably would have done worked examples in the class in front of the students, so there are numerous examples in this book. Recreate the experience of learning astrology in Roger’s classroom, but from the comfort of your own twenty-first-century home rather than a hard classroom bench.

Dr Chris Mitchell is a long-standing tutor at the Sophia Centre (Institute of Education & Humanities) at the University of Wales Trinity Saint David (UWTSD) in Lampeter, where he teaches on the MA in Cultural Astronomy & Astrology, tutors distance-learning students, marks student work and delivers lectures for summer schools and one-day events.
He holds an MA in Cultural Astronomy & Astrology (Bath Spa) and completed a PhD at the University of Leicester focused on medieval English astrology; his doctoral thesis, titled “Roger of Hereford’s Judicial Astrology: England’s First Astrology Book?”, is available online and examines the surviving manuscripts of Roger’s text, its transmission and its role in twelfth-century England.
Mitchell’s principal research interests are medieval astrology and the manuscript/translation traditions that brought astrological knowledge from the Islamic and Jewish worlds into Latin Europe. He works closely with primary manuscripts, paleography and codicology, investigating how texts were transmitted, translated and taught; he has published on transmission networks, the role of Jewish scholars in knowledge transfer between the eleventh and fourteenth centuries, and case studies such as prognostications and specific medieval authors.
From his doctoral research and subsequent work Mitchell produced an edited and commented edition of Roger of Hereford’s text: England’s First Astrology Book: Roger of Hereford’s Judicial Astrology (Almuten Figuris Publications, 2021), which presents a critical text, translation and contextual commentary intended both for scholars and informed readers of the history of astrology.
In addition to monographs and thesis material, Mitchell contributes chapters and articles to collected volumes and conference proceedings, and regularly presents at Sophia Centre events, summer schools and specialist conferences on the history of astrology. He combines rigorous manuscript work with public-facing lectures and short courses, bridging academic research and wider pedagogical outreach.
Outside purely academic publishing, Mitchell has undertaken practical projects—creating lunar and ephemeris tables, producing astronomical/astrological tables for publishers, and offering technical consultancy services in astrological calculations and software—work that demonstrates a practical competence alongside his historical scholarship.
He is active in the broader astrological and academic community, contributing to conference programmes and academic networks; his work is notable for its careful use of primary sources, attention to how medieval educational contexts shaped astrological texts, and for situating English medieval astrology within the wider Mediterranean translation movements.
Useful primary references and entry points for further reading include his UWTSD staff profile (which lists roles and contact details), the online copy of his PhD thesis, and the 2021 edited volume of Roger of Hereford’s Judicial Astrology
