In Imperial times, we have been told, exotic eating was the rule. Like most gross exaggerations, this one contains an element of truth. From Petronius, Juvenal, Lucian, Martial and other Roman writers we learn that peacocks, flamingos and herons were in fact served with their full plumage carefully replaced after cooking; that wolves, hedgehogs and puppies were considered choice eating; that dormice-small rodents resembling squirrels-were confined in barrels to keep them from exercising and were force-fed to obesity for the table.
