On the other hand, Nova N 176 is written in a known (albeit mostly lost) language and there's relatively little indication of the content. Whereas Voynich is written in a mysterious unknown language/cipher and has fascinating illustrations that inspire curiosity. Voynich also has the "advantage" of resembling a European language, which makes studying it much more accessible to scholars and amateurs who lack the necessary training in non-European languages. (In other words, the problem is not that people are choosing to study one vs. the other, it's more that the set of people who have the necessary training to study Nova is either smaller, or doesn't have as many people interested in this sort of puzzle.)
