No text, but a visual code

[Antonio García Jiménez]

Mary D'Imperio saw in the Voynich drawings: plants, pipes and jars, a unit of style that for her must have some symbolic meaning. She suggested that the draftsman of the pictures was more accustomed to, and interested in, making mechanical or structural sketches than in illustrating natural objects.

This suggestion seems very relevant to me because it relates the Voynich to the work of engineers of the time such as Giovanni Fontana.
