A chandelier is a ceiling-mounted fixture with two or more arms bearing lights. Modern chandeliers are often very ornate, containing dozens of lamps and complex arrays of glass shapes to illuminate the room in many intricate patterns. The earliest chandeliers were used in medieval churches and abbeys to illuminate large halls. Developments in glass making in the early 18th century led to an increased production of lead crystal. The light-scattering properties of this highly refractive glass quickly became a popular addition to the form, leading to the classic crystal chandelier.
