Artificial Intelligence Helps Decode Centuries-Old Borgia Cipher in Vatican Library

The Vatican Apostolic Library has housed a 408-page handwritten manuscript for more than four centuries that has never been successfully read. Artificial intelligence may provide the key to solving the riddle of encrypted texts that have remained unsolved for centuries.

The Vatican Apostolic Library has preserved a 408-page handwritten manuscript for more than four centuries, much of whose content has remained a mystery. The text uses 34 unusual symbols along with individual Latin letters, and the title page is written in Arabic. The cipher key — known as the Borgia cipher — was lost long ago, and many pages of the manuscript, now centuries old, have been damaged by the ravages of time.

An Unsolved Cryptographic Puzzle

The Borgia cipher is not the only such case in history. The world contains numerous texts and documents that have not been decoded for centuries or even millennia. The history of cryptography is full of such puzzles that have resisted intellectual effort across generations.

The Role of Artificial Intelligence in Breaking Ciphers

Now the situation may change. The advancement of artificial intelligence opens new possibilities precisely for analyzing such complex and previously unsolved encrypted texts. Machine learning algorithms are capable of detecting patterns and connections that escape the human eye — especially in large volumes of data, where traditional methods have proven insufficient.

According to experts, artificial intelligence could be the tool that breaks through the barriers that humans have struggled against for centuries. In the case of the Borgia cipher, this means analyzing thousands of symbol combinations to find the hidden linguistic pattern.
