No text, but a visual code

[Antonio García Jiménez]

We live surrounded by artificial light and we do not realize the importance that natural light had in those days. In the Northern Hemisphere, now that it is spring and we are approaching the solstice, we see how light is gaining time over darkness. Light is vital for plants, which is why perhaps the signs of Aries and Taurus are repeated in the Voynich, to underline the idea of their importance in the plant cycle. 

Does anyone think there may be another reason?
