Antonio's post mentioning astronomy is relevant.
If we take the Voynich illustrations at face value, it seems the makers cared about plants, stars and medicine/balneotherapy.
If they cared enough about these topics to write a whole book about them, I would think that meteorological and astronomical events, as well as medical events (inventions, discoveries, translations of important foreign works, droughts, epidemics, great conjunctions and comets, etc etc etc) might be at least as important to them as the outcome of the battle of Inverlochy.
