No text, but a visual code

[Antonio García Jiménez]

Thanks David, it was just a rhetorical question on my part. A way for the forum to reflect on the origin of this symbol.

Angle symbols were standardized in the 16th century, but their shape is likely inspired by earlier examples. 

The glyph (o) is the most common of the Voynich script, a book with numerous astronomical/astrological pages.

Is it a coincidence, when there is also that series of o's in a circle of f70r1 that gives the impression of being the degrees of the sphere?
