Pizza? At Pompeii?

Archaeologists at Pompeii have uncovered a wall painting which seems to show a pizza, or something like a pizza; a pizza precursor, pre-pizza, or maybe a pizza-oid type of entity. The pizza, foccaccia or bread in the image doesn't have tomato sauce on it, of course. Tomatoes are a new world fruit/vegetable and weren't brought Europe until the 15 or 1600s at the earliest and the first evidence of their being used in cooking in Italy wasn't until the late 1600s. But still... It's bread, with a topping of maybe fruit and/or vegetables, and/or pesto, and spices and it sure looks like pizza!
