Researcher Lisa Davis, a leading Voynich manuscript expert, observed non-consecutive pages within the same bifolio (double sheet) shared graphic elements, like pages 78 and 81. To investigate, she developed an AI to analyze symbol and word likenesses. The AI confirmed a high affinity between seeming
