Rome: the empire of pork
Claim: pork was the favorite meat of ancient Rome. Evidence: the Roman cookbook known as Apicius has more recipes for pork than for any other meat; the Romans made sausages, among them the Lucanian sausage still remembered in Italian and Portuguese names, and the Greek geographer Strabo reports hams shipped to Rome from Gaul.
Ask: why would pigs suit a city of a million people better than cattle?
