A vast amount of tropical plants grow in India, which was connected to medieval Europe by trade routes.
Green water was not uncommon in medieval imagery, it's only in modern times that we think of water as blue. Google images of "De Balneis Puteolanis" for examples.

In the VMS, the gals contrast their new bathing in the American swamps with their old bathing in the Roman baths of Europe. Roman baths (built on top of arches to allow heating from underneath) date back to classical times and can be found all over Europe. Some of them are still in use today. And they are of no help to you for dating the VMS to the 15th century.

Of greater importance is the fact that no other work written wholly or partially in Voynichese has ever been found in Europe. Even in medieval times European writing and culture was well-documented. Could the mysterious absence of more examples of Voynichese in Europe be a sign that maybe the VMS wasn't compiled in Europe?

Meanwhile, a Professor Emeritus of Anthropology at Yale University (where the VMS is now kept) wrote:

"Our knowledge of ancient Maya thought must represent only a tiny fraction of the whole picture, for of the thousands of books in which the full extent of their learning and ritual was recorded, only four have survived to modern times (as though all that posterity knew of ourselves were to be based upon three prayer books and Pilgrim's Progress)."

There is LOTS of Mayan writing on stones and temples, and some in manuscripts, and it is pictograms, similar to Egyptian writing in concept. The shapes and the way they are presented has nothing in common with the VMS.

The point is that we do not how many of those thousands of books that were destroyed might have been written in Voynichese. For sure, the Spanish Inquisition would have made no effort to distinguish VMS script from hieroglyphics.

Do you know ANYTHING about the Spanish occupation? because you talk as if you're inventing an alternate history. Some of the missionaries did make an effort to record some of the icons and style of communication of the local people.
