Can Artificial Intelligence solve the mysterious anagram from the church of the Poor Clares in Bratislava?

Abstract

A mysterious anagram was found in the Church of the Poor Clares in Bratislava, but as far as we know it has never been successfully solved. The anagram contains81 symbols, including specific diphthongsAE, CH, and GY. Unlike other anagramstypical of that age, the symbolsare not ordered alphabetically. We suspectthat a specific order of symbols is relatedto the original order of symbols in theplain text. Even with the suspected orderof letters, the number of possible plain textcandidates is too high to obtain the originaltext with standard methods. We examinealternative scoring methods based onmodern AI text similarity to improve thequality of the candidate plain text candidates.
