Colourless transparent glass with a yellow tinge, applied blown foot and handle, enamelled and gilded. Mosque lamps of glass, enamelled and often with gilding, survive in considerable numbers from the Islamic art of the Middle Ages, especially the 13th and 14th centuries, with Cairo in Egypt and Aleppo and Damascus in Syria being the most important centres of production.
They are oil lamps, usually with a large round bulbous body rising to a narrower waist, above which the top section is flared. There is usually a foot so they can be placed on a surface, but they were normally used suspended by chains that went through a number of loops on the outside of the body. They were used to light mosques and other buildings in mosque complexes, in large spaces in groups hanging from a circular metal frame.
