Google DeepMind and historians created an AI tool called Aeneas that can predict the missing words in Latin inscriptions carved into stone walls and pottery sherds from the ancient Roman Empire.

Latin inscriptions from the ancient world can tell us about Roman emperors’ decrees and enslaved people’s thoughts – if we can read them. Now an artificial intelligence tool is helping historians reconstruct the often fragmentary texts. It can even accurately predict when and where in the Roman Empire a given inscription came from.
“Studying history through inscriptions is like solving a gigantic jigsaw puzzle, only this is tens of thousands of pieces more than normal,” said Thea Sommerschield at the University of Nottingham in the UK, during a press event. “And 90 per cent of them are missing because that’s all that survived for us over the centuries.”

The AI tool developed by Sommerschield and her colleagues can predict a Latin inscription’s missing characters, while also highlighting the existence of inscriptions that are written in a similar linguistic style or refer to the same people and places. They named the tool Aeneas in honour of the mythical hero, who, according to legend, escaped the fall of Troy and became a forebear of the Romans.
“We enable Aeneas to actually restore gaps in text where the missing length is unknown,” said Yannis Assael at Google DeepMind, a co-leader in developing Aeneas, during the press event. “This makes it a more versatile tool for historians, especially when they’re dealing with very heavily damaged materials.”
The team trained Aeneas on the largest ever combined database of ancient Latin texts that machines can interact with, including more than 176,000 inscriptions and nearly 9000 accompanying images. This training allows Aeneas to suggest missing text. What’s more, by testing it on a subset of inscriptions of known provenance, the researchers found that Aeneas could estimate the chronological date of inscriptions to within 13 years – and even achieve 72 per cent accuracy in identifying which Roman province an inscription came from.
