You'll notice earlier in the thread I've been reading about pizza and it's origins. I posted one of the earliest newspaper items I could find originating from Italy to refer to it. I went back through searchable archives to the 1600s. There has been nothing earlier that I found. I also have some decent tomes on flatbreads from around the world. Nothing I see supports the idea that any Romans had what we call pizza before the Neapolitans. Focaccia for example isn't pizza and isn't and has never been thin and crisp.

The closest Rome-wise I could find is that the ancient Romans developed something completely different from pizza called "placenta cake" which is a multi layered crusty doughy crisp desert type thing with layers of dough and honey - almost sounding baclav'ish .... they certainly didn't invent what most would say is pizza. The Greeks came closer to it. In any event, a thin base doesn't mean crisp and crunchy.

Most people that are interested in pizza agree that pizza as we know it was developed in Naples in the late 18th century .... it sounded like what we call plain old marinara ...... but I find it is best not to argue ... no good seems to come of it ......
