Magnifying Glass Coloring Pages

“The evidence indicates that the use of lenses was widespread throughout the Middle East and the Mediterranean basin over several millennia”. The earliest explicit written evidence of a magnifying device is a joke in Aristophanes’s The Clouds from 424 BC, where magnifying lenses to ignite tinder were sold in a pharmacy, and Pliny the Elder’s “lens”, a glass globe filled with water, used to cauterize wounds. (Seneca wrote that it could be used to read letters “no matter how small or dim”). A convex lens used for forming a magnified image was described in the Book of Optics by Ibn al-Haytham in 1021. [verification needed] After the book was translated during the Latin translations of the 12th century, Roger Bacon described the properties of a magnifying glass in 13th-century England. This was followed by the development of eyeglasses in 13th-century Italy.
