what greek roots were used to create the word photography
Photography The word "photography" was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), "light"[2] and γραφή (graphé) "representation by means of lines" or "drawing",[3] together meaning "drawing with light".[4]
History of optics The earliest known lenses were made from polished crystal, often quartz, and have been dated as early as 750Â BC for Assyrian lenses such as the Nimrud / Layard lens.[2] There are many similar lenses from ancient Egypt, Greece and Babylon. The ancient Romans and Greeks filled glass spheres with water to make lenses. However, glass lenses were not thought of until the Middle Ages.
