The modern mind is used to neat distinctions and a more or less monolithic theoretical scaffolding where everything finds its little place. To our sensibility, what belongs to natural science does not belong to literature or art, let alone to astrology or occultism. Though some eccentrics try to straddle the gorge, within the current worldview they must remain what they are: eccentrics. This is largely a consequence of the evolution of science away from the mother root of philosophy and the triumph of the technical-scientific worldview. It is neither a good process nor a bad one: it is what it is, but it hasn’t always been this way.

Pietro d’Abano, who lived between the XIII and XIV century, was, like many of his time, an encyclopedic learner. This was certainly easier back then, when owning a couple of dozens books was considered a marvel and the hyperspecialization typical of our contemporary organization of knowledge hadn’t yet taken place.

The extent of Abano’s involvement in occult practices is not clear. The famous grimoire Heptameron (Book of the Seven Days) is traditionally attributed to him, though it is, in actual fact, an anonymous work. What we do know is that his knowledge of languages allowed him to study many authors (like the Averroes or Ibn Ezra) who had considerable influence on the later development of magical theory, though this influence is still little understood by contemporary occultists.

We also know that he taught a number of subjects ranging from medicine to astrology, and that he was a very adept astrologer. This is not a unicum in the history of science. Astrology was one of the few forms of divination that was, if not tolerated, at least not as consistently persecuted as other branches of occultism in the Middle Ages, largely due to the fact that a reasonable argument could be made that the astrological influence of the planets was a natural consequence of how the cosmos was believed to work according to the Platonic-Aristotelean view accepted by the Church. It was simply not always practical to distinguish astrology as astronomy from astrology as divination, though attempts were made.

Finally, Abano is the subject of a number of urban legends. For instance, he was brought before the inquisition twice, largely due to his immense erudition. Once he was acquitted, the second time he was condemned. Unfortunately, he died in custody before the sentence had been pronounced, so the tribunal ordered his body exhumed and burned. But they dug up an empty grave, since a friend of the philosopher had gotten to his body first. This fact alone was enough to cement in people’s mind the image of Abano as an ominous magus and necromancer whose body was capable of disappearing from the grave.

As for the present book on Geomancy, it is not a stretch to think that someone as versed in astrology as Abano should be interested in this form of divination, which, at least in Europe at the time, was reduced as much as possible to astrological principles. The treatise is divided into four books: in the first, Abano explains the principles and astrological correspondences of geomancy; in the second, he discusses the meanings of the various houses and the principles of geomantic perfection; in the third, he gives examples of the meanings of the figures in the houses; in the fourth, he talks about the good or bad fortune of the figures depending on which figures they derive from.

What makes this book an interesting read for any student of geomancy is that it confronts us with a way of reading the Geomantic Shield that is not typical of how geomancy has been rationalized in the late XX and early XXI centuries. This is in itself worthy of consideration, especially because it proves beyond doubt that the distinction between Shield Chart and Astrological Chart is artificial and only serves to complicate matters. Furthermore, Abano’s interpretation of the figures affords us a rare glance in the workings of the mind of an adept of geomancy, by whose example we can derive solid principles for interpreting our divinations. Abano’s examples are therefore not meant to be taken as the last word, but as a contribution to our study of the interrelation of the Geomantic figures.
