L ead-tin yellow can also be seen in the blouse worn by the willing young lady in Vermeer’s The Procuress. The beautiful orange-red coat worn by the dashing young man about to hand the girl her wage was created with vermilion (also on Monet’s list), a mercury pigment (HgS). It was common to enhance its richness by glazing over it with transparent organic reds, such as madder lake. The exquisitely painted lobster in the de Heem still life is also vermilion. The lemon peel, a frequently used device to show the artist’s skill, also has the dimpled effect in the paint itself. Orpiment and realgar, naturally occurring minerals containing arsenic, were known in antiquity as far back as ancient Egypt and Mesopotamia. Mercuric sulfide, reportedly derived from the natural mineral cinnabar found in the mines in Almadén, Spain, was used in ancient Rome. White lead was also known and used by the Romans, but its toxicity was perhaps not well understood, since it found a use in women’s cosmetics! The accumulation over time of the deleterious effects of poisons became known with advances in modern medicine and biochemistry. An interesting case in point is that of the great master Peter Paul Rubens.
