Italian officials unveiled the discovery of a 2,000-year-old basilica that archeologists have attributed to Vitruvius, the ancient Roman architect, at a press conference on Monday, according to a report in Reuters.

The ancient basilica, which would have been used as a public building in ancient Rome, was built at Fanum Fortunae and completed in 19 BCE. It is the only known building by Vitruvius and is referenced in De architectura, the only treatise on architecture to survive from antiquity. Vitruvius would later be immortalized in Leonardo da Vinci’s Vitruvian Man drawing, which mapped the architect’s ideals of portion onto the human body.
