2,000-Year-Old Carbonised Bread from Herculaneum Reveals Ancient Roman Baking Methods

When Mount Vesuvius erupted in AD 79, a round loaf of bread remained inside an oven in the ancient Roman town of Herculaneum, where it was buried and carbonised under volcanic debris. Discovered during excavations in 1930, the artifact survived nearly two millennia, offering researchers a rare look at ancient food preparation.

Insights from the Herculaneum Archaeological Park

Information from Italy's Herculaneum Archaeological Park indicates that Roman bakers often cut lines across the surface of round, flattened loaves before baking to allow easy portioning.

• Panis Quadratus: One common design featured eight sections, named after the Latin word 'quadra'.
• Alternative Designs: Archaeologists also recovered two well-preserved loaves with six sections each from the House of the Brick Altar and the Palestra area.
• Bakers' Stamps: Loaves often carried rectangular stamps, such as the letters "VM" found on a six-section loaf, which likely helped identify ownership when households used shared public ovens.

Modern Recreation and Other Finds

The British Museum featured the loaf in a 2013 exhibition, later sharing a recipe and preparation video in July 2020 based on a recreation by Italian chef Giorgio Locatelli. The process used wholemeal or plain flour, spelt or buckwheat flour, salt, sugar, water, and biga acida (sourdough). Additionally, archaeologists uncovered smaller flatbreads with geometric and plant-like patterns along the Lower Decumanus, which were likely displayed for sale in ancient food shops.
