No text, but a visual code

[Antonio García Jiménez]

That's a good way to avoid having to think more. For example, I see in You are not allowed to view links. Register or Login to view. that strange composition of a square joined to a triangle without a base and another sign above. How can that be a Capital, a ligature, abbreviation or a number?

I have never seen such a thing in a medieval manuscript and I have seen quite a few. The only thing it resembles is some type of geometric element, something used in the world of astrology.
