Rembrandt’s Golden Glow

[Paul Ferguson]

"Scientists found arsenic sulfide pigments in “The Night Watch,” arguably the artist’s most famous painting...Our research involved examining 17th-century trade records, apothecary pharmacopeias, price lists and contemporary writings on metallurgy,” lead author Nouchka de Keyser, an Operation Night Watch team member, tells Hyperallergic. The researchers also combed through painters’ manuals and alchemical literature, including Danish historian Ole Worm’s Museum Wormianum."
