No text, but a visual code

[Antonio García Jiménez]

The best indication that (o) can represent a star is its union to (q). This gliph, like all of them, is not a letter but a symbol with its own meaning, an arrow-shaped symbol that indicates movement. It doesn’t often occur in labels because labels don't move. It occurs almost always at the start of a 'vord' and before (o). It may be to indicate that it is a certain star that is moving and not another.

Voynich's script may be a representation of the movement of the celestial sphere
