A computer science student has discovered the first word in an unopened Herculaneum scroll using machine learning models. The scroll is one of many that were buried and carbonized by the eruption of Vesuvius in 79 AD. The discovery was made possible by a competition that encouraged contestants to develop open-source tools and techniques to virtually unwrap and read the scrolls. The word 'porphyras', meaning 'purple', was identified and verified by a team of papyrologists.
