I dont know about anyone else but I sometimes find it a bit bewildering keeping up with all the astrologers during the medieval and early modern era. The field seems quite crowded at times. For hellenistic astrology Project Hindsight have already put out this handy online catalogue of important astrologers.

http://www.projecthindsight.com/reference/catalog.html

Benjamin Dykes translations are also highlighting the role of important Persian and Arabic astrologers. However, I thought it might be handy to do a DIY chronology of the main european astrologers in the medieval and early modern era. My focus is more those that left writings behind although knowledge of good practitioners is important too. Not everyone on my list is an astrologer-for example Saint Thomas Aquinas and Saint Albertus Magnus. However, these are figures with important views on astrology from the Church. Equally, some figures such as Thomas Digges or John Flamsteed were astronomers that were sympathetic to astrology.

Its obviously not a complete list but a starting point for others to expand upon. For my own reference I am adding personal notes about most of these astrologers. I have taken a liberty with nationalities. Clearly Italy and Germany were not united nations in this period. On the other hand I have listed astrologers in medieval nations that are now part of a larger state: eg. Scotland, Aragon etc.

We do seem lacking in Spanish, Portugese and eastern European astrologers from this era. No doubt an anglophile bias in our understanding. Please chip in with other suggestions. If you have any suggestions about any important figures you feel have been left out please post your comments.

nice list, i will put aside.

Lorenzo Bonincontri, from San Miniato, Tuscany.

I will add Giovanni Magini (1555-1617) from Padova (Padua). Many like North say that he was the author of Placido house system, obviously on the ground it was the original Ptolemaic method.


I'm leaving a couple of days in order to hear Bezza on the great conjunctions, i will read you when I'm back

To Mark,

Thank you!

Just to clarify, North certainly didn't think it was the original Ptolemaic method! (Apologies for the off-topic remark.)

I was waiting for such a comment from you, I know your opinion about Ptolemy house system
Anyway you are right in putting things better, obviously I meant that were Magini/Placido to support this idea.

We do seem lacking in Spanish, Portugese and eastern European astrologers from this era.

The only one I have is "the book of crosses" by Oneydalla (translated by order of Alfonso X)

Lorenzo Bonincontri, from San Miniato, Tuscany.

I will add Giovanni Magini (1555-1617) from Padova (Padua).

Thanks Margherita!

I would have added town of birth for the above list but its not always known in the older figures. I have gone back and added for for those I have available.

I plan to update information in the original post so hopefully this thread can be ongoing as people come up with new suggestions. I am also aware of a few omissions of my own I should have added.

Thanks for the information on Lorenzo Bonincontri. I was trying to hunt down information online on 'Laurentinius Bonincontrius' but it was scant. I do have the old track Project Hindsight translation of his book on elections but I didn't have it to hand.

Geographically there are massive gaps here. Is that a reflection of reality or simply our ignorance of what was happening? For example, what was happening in eastern europe during this era? The only person I have on the list is Copernicus. Apart from the towering figure of Tycho Brahe what did the Scandanavian countries offer us? Then there is astrology in the Byzantine world. I have added a couple of astrologers that moved west but there must have been many others. Astrology didn't die out in Byzantium before the fall of Constantinople in 1453. Indeed, the spread of classical scholars and their libraries were undeniably factors that kick started the Italian renaissance.

Spain and Portugal represent the other important route through which classical knowledge was transmitted across Europe. Indeed this could be called nothing less than a crosssroads of Islamic, Christian and Jewish cultures. Its little wonder that Michael Scot first set out for Spain to study at the universities of Toledo and Cordoba established by the Arabs.

If I understand correctly it was translated by order of Alfonso X from Arabic into Castilian in 1259 by Yehuda Al-Cohen. Was Oneydalla an astrologer based in Muslim Spain?

I suspected the lack of information on astrology in medieval eastern europe simply reflected lack of research available in English rather than its non-existence.

I was therefore pleased to come across this website by Darin Hayton. He is a historian of science at Haverford University, Pennsylvania, USA and his academic specialism includes the medieval astrology of Poland and Hungary.

http://www.haverford.edu/hist/faculty/h ... l#fortunes

Contrary to many standard astrological histories Poland and Hungary were significant centres of astrological activity in their own right during the medieval period. Noteable 15th century Polish astrologers listed by Darin Hayton include the following:

Maritn Krol, Martin Bylica, Jan Stercze, Johannes Glogau and Albertus Brudzewo

Martin Bylica in particular seems to have enjoyed particular prominence in his own time. His writings have been preserved in locations as distant as Paris, France and Novogorod, Russia.

To quote from the link:

In 1467 the Polish astrologer Martin Bylica arrived in Pozsony (Bratislava), where he and Regiomontanus took up chairs in astronomy at the fledgling university, the Academia Istropolitana. By the summer of 1468 he had succeeded in gaining Matthias Corvinus?s generous patronage and soon become the king?s chief advisor. Over the next two decades Bylica tirelessly accompanied Corvinus on military campaigns and diplomatic missions, served as liaison between Corvinus and the faculty at the University of Vienna, and helped to develop an observatory at Corvinus?s court in Buda.

Darin Hayton has also done research on Cracow University as an important centre of astrological study in medieval Poland.

The Placidus house system is based essentially on an understanding of the directions by Ptolemy. Magini has shown in his book, "Primi Tabulea Mobile" by 1604, the calculation of the different directions in the way of Regiomontanus and also in "Ratio Ptolemy".

Obviously- to make Martin unhappy it should be the viam rationalem, quam iuxta Ptolemaei formam....

Hello Magherita,

in correct latin (as also in this book), you are absolutely right!
