Dartmouth Toxic Metal Research: Lead - Versatile Metal, Long Legacy
Description
A taste for lead For winemakers in the Roman Empire, nothing but lead would do. When boiling crushed grapes, Roman vintners insisted on using lead pots or lead-lined copper kettles. "For, in the boiling," wrote Roman winemaker Columella, "brazen vessels throw off copper rust which has a disagreeable flavor." Lead’s sweet overtones, by contrast, were thought to add complementary flavors to wine and to food as well. The metal enhanced one-fifth of the 450 recipes in the Roman Apician Cookbook, a collection of first through fifth century recipes attributed to gastrophiles associated with Apicius, the famous Roman gourmet. From the Middle Ages on, people put lead acetate or "sugar of lead" into wine and other foods to make them sweeter. Lead touched many areas of Roman life. It made up pipes and dishes, cosmetics and coins, bullets and paints. Eventually, as a host of mysterious maladies became more common, some Romans began to suspect a connection between the metal and these illnesses. But the culture’s habits never changed, and some historians believe that many among the Roman aristocracy suffered from lead poisoning. Julius Caesar, for example, managed to father only one child, even though he enjoyed women as much as he enjoyed wine. His successor, Caesar Augustus, was reported to be completely sterile. Some scholars suggest that lead could have been the culprit for the condition of both men and a contributing factor to the fall of the Roman Empire. A form of lead intoxication known as saturnine gout takes its name from ancient Rome. Saturn was a demonic god, a gloomy and sluggish figure who ate his own children. The Romans noticed similarities between symptoms of this disorder and the irritable god, and named the disease after him. Scientists have since learned that while there are similarities between saturnine gout and primary gout - such as elevated blood uric acid levels - these are in fact two distinct diseases.
