Italy is recognized as the birthplace of pizza, that incredible edible disk of toasted bread crowned with cheese and other toppings. Proto-pizzas trace back to the early Roman Empire. Initially, pizza consisted of wood-fired flatbread, frequently topped with olive oil, salt, cheese and garlic. It may surprise readers that the first pizzeria to open in ancient Rome is thought by a few to have been a small shop in Pompeii displaying an ancient Latin inscription above its doorway, “vis colligendi pizzae,” or “the gleaning power of pizza.” I know, the similarity is amazing! Gleaning was a big thing back then, and this is the earliest known writing suggesting the Romans believed that nearly anything could go on a pizza.
