Gout was once a common malady that immobilized many of the upper class males of ancient Rome and imperial Britain. Both societies blamed it on too much rich food and wine, and they may have been right. The Roman writers, Seneca, Virgil, Juvenal, and Ovid all poked fun at the sufferers of gout, as did the London cartoonists; the popular belief was that it was a just punishment for over-indulgence. Physicians knew of the pain it caused and discovered that it was due to sharp crystals of uric acid between the joints of the bones; but what caused these to form? Among those affected by gout were Benjamin Franklin, one of the founding fathers of the United States of America, British Prime Minister William Pitt, poet Alfred Lord Tennyson, biologist Charles Darwin, and the founder of Methodism, John Wesley. It has been suggested that Alexander the Great, Kubla Khan, Christopher Columbus, Martin Luther, John Milton, and Isaac Newton also suffered its agonies. In the last century, it was found that more than a third of those suffering from gout had high levels of lead in their blood. It now seems likely that earlier generations had exposed themselves to gout by a fondness for port wine, which was invariably tainted with lead, and kept in lead crystal decanters. At various times in the 1700s, the British were at war with the French and no longer imported their wines or brandy, although quite a lot was smuggled into the country. Instead Englishmen turned to drinking the wines of their most faithful ally, Portugal. These, like port and Madeira, contained lead, and they became so popular that by the 1820s more than 20 million litres of port were being imported annually. Bottles of this age have been analysed for their lead content and shown to have in excess of 1 ppm suggesting that the risk of serious lead poisoning from such drink was relatively low, although it would have had an effect. Indeed the lead may have simply served as an irritant to the gut, which is why a glass of port at the end of a meal was reputed to have a laxative effect by the following morning.
