Besieging a Castle: How Not to Do It.
If you haven’t yet read Bonatti’s On War, you owe it to yourself to do so. This is not so much because it will come in handy in your daily life (note: if you routinely lay sieges as part of your workday, you may need a new career), but because it is a fascinating firsthand account of a “field” astrologer in the 13th century Bonatti had participated in many military expeditions, and there are several stories of his astrological prowess saving the day (check out Holden’s History of Horoscopic Astrology) The text is also an excellent illustration of the fact that even then, the commander did not always listen to his astrologer’s advice!
In this post, I will examine a chart from 1261, when Bonatti went on an expedition with the then-podesta (a type of military commander) of Urbino, Guido di Montefeltro. By way of historical context, Guido was one of the Ghibelline faction and was consigned to Hell by Dante Alighieri in Canto XXVII of his Divine Comedy. Guido was apparently quite a character; he ran Urbino for over thirty years, no small task in those unstable times, and at the end of his long life became a Franciscan monk, presumably to atone for his sins. As an astrologer, Bonatti earned a place in Hell also, though Dante gives every indication of possessing quite advanced astrological knowledge himself! In our chart, Guido and his army were besieging a castle, and the commander wished to know whether they would take it or not.
Technical Details: I am using Robert Zoller’s translation of On War, which I would recommend highly to interested readers. Though the place, date and time for the chart are not given, the closest approximation I could find is October 11, 1261, 9:05 am GMT, Urbino, Italy. Interestingly, the Sun and Moon for this chart are where they should be, but several of the other planets are in different degrees from Solar Fire’s calculation.
