Kohl Flasks. Dimensions: 2 x 3/4 in. (5.1 x 1.9 cm). Date: probably 10th-12th century.These charming objects were designed to hold kohl, a black cosmetic powder applied around the eyes. In the past, kohl was widely used by men and children as well as women. It was thought not only to accentuate the beauty of the eyes, but also to guard against the glaring sun, ward off evil, and discourage eye disease. The narrow drill hole at the top of these flasks would have accommodated a slender stick to collect the cosmetic. Museum: Metropolitan Museum of Art, New York, USA.
