A Visual Grammar for Goetic Sigils.
The 3rd image above shows the most common glyphs (individual graphic units) that can be found in the sigils (seals) for Goetic spirits.
A hypothesis is that the sigils represent some attributes or characteristics of the spirits in question, in the same way that a company logo is meant to represent a corporation.
We can see that many of the sigils exhibit “bilateral symmetry”, which is also a property of biological organisms (including humans).
An additional hypothesis is that the seals represent a “circuit diagram” for the spirit, showing how it processes what all non-material entities thrive on: our attention.
