dangerous light


One of my favorite paintings in the Cleveland Museum of Art: Jeptha Homer Wade: Nathaniel Olds, 1837.

From the item description:
The green-tinted spectacles worn by Olds were designed to protect the eyes from the intensity of Argand lamps, a type of indoor light used during the early 1800s. These lamps burned whale oil, and many people worried that its bright flames might damage eyesight.The painter of this portrait founded the Western Union Telegraph Company in 1854 ... His grandson, Jeptha Wade II, was a founder of the Cleveland Museum of Art and donated the land upon which it stands as a Christmas gift to the city in 1892.
