I added a new web page on the Tower of the Winds, an ancient building in Athens.
The standard modern view is that it was "scientific" you know a big utilitarian clock tower.
The webpage is a description of the Tower by a 17th century Turkish traveler, who describes a great deal of astrological talismanic lore regarding it. Very interesting and reminiscent of the larger scale astrological talismanic workings in the Book of the Treasure of Alexander. and Adocentyn, the astrological city of Hermes Trismegistus in Picatrix, Bk IV ch 3.
We tend to think of talismans as jewelry, as rings or medallions. In fact, De Imaginibus of Thabit Ibn Qurra clearly is talking about statuettes and many of the Picatrix Bk IV chapter 9 mansions images are also to be made as statuettes, often of wax. Certainly magic mirrors and swords, for example, are part of our traditional view of talismans, but almost anything, up to a whole city, can be created as an astrological talisman. These forces permeate all material things and if we pay attention orient us to the spiritual cycles and forces that underlie everything in the material world.
