Not far from the forum is the sign of a shop belonging to a local baker Podiscus Pricus, in whose building historians say was a wood-fired oven. There were likely other ovens across Pompeii, too similar to a small one found in the Greco-Roman market area of Naples. Some 4 feet in diameter, these ovens would not have been a good shape for bread, but you could bake smaller rounds: in other words, pizza -- that classic Italian street food staple.
