Natural History and Environment

As everybody knows, oysters are the ultimate aphrodisiac. Casanova is said to have eaten 50 raw oysters every morning with his mistress of the moment, in a bathtub designed for two. Whether oysters truly have exciting properties is open to debate, but like all seafoods, they contain high amounts of phosphorus and iodine, which are believed to be conducive to stamina. Author and food expert M.F.K. Fisher wrote: 'There are many reasons why an oyster is supposed to have this desirable quality ... Most of them are physiological, and have to do with an oyster's odour, its consistency, and probably its strangeness.' As well as an aphrodisiac, the oyster has since the earliest times been an inspiration to philosophers, artists, poets, chefs, gourmets, epicures and jewellers. It has been pursued by poachers and thieves, and defended by oyster-police and parliaments.
