How many people could have written the Voynich?

I would say another not unimportant requirement is that they need some technical skills - which starts with knowing how to write, sharpen the pen correctly etc.

If a further requirement is that he must have been acquainted with the Alsace style of art, had some disagreements with the Roman Church since he used no obvious religious signs, showed interest in building swimming pools, wrote in a language that has not yet been written, and was most likely a mystic, you can narrow down the search to Nicholas Kempf from Strasbourg, who studied and for some years taught at Vienna University, served as a prior of two Carthusian monasteries in the Slovenian speaking land, wrote over thirty books of philosophical works, poems, theological treaties (including Mystical theology), and bought a land for the monastery where the monastery build an open swimming pool for public baths.
