Finemosque lamps areoil lamps that typically have a large round body and a narrower neck that flares towards the top.[1] They were often made with internal containers to be filled with oil and a wick to produce light.[1] They were usually made ofenamelled glass, often withgilding.[2] Some were also made inIslamic pottery, though this was much less efficient for actual lighting. These lamps were normally hung by a circular metal frame and suspended by chains that went through a number of loops on the outside of the body. The circular frames continue to be used in many mosques today, but with plain or frosted glass lamps for electric lighting.
The techniques used are typical of contemporaryIslamic glass, with the enamel decoration applied to a pre-fired plain body, and the whole then fired for a second time. The vibrant colors present from the enameling process of mosque lamps come from a variety of materials including lapis lazuli for blue, naples yellow for yellow, naples yellow and cobalt for blue, and lead-based enamels for red and yellow colors.[3] The coloured decoration may includeQur'anic verses, especially the first part of theAyat an-Nur or "Verse of Light" (24:35, see below), inscriptions and heraldic emblems recording the donor, as well as purely decorative motifs.[2] By the 15th century production of all types of fine glass was in steep decline, a sign of which is that in 1569 theOttomanGrand VizierSokullu Mehmed Pacha ordered 600 plain lamps ofVenetian glass, perhaps to be decorated elsewhere.[4]
TheOttomans also made lamps of similar form inIznik pottery, andShah Abbas I of Persia gave plain silver lamps to hang by the tomb ofShaykh Safi atArdabil;Persian miniatures show other examples from the 16th century in gold or brass and silver. Such opaque materials were much less effective as lighting, but the purpose of the lamp was symbolic as well as practical, related to the "Verse of Light".[5] Mosque lamps are often shown in profile at the head of aprayer rug for the same reason.[6] The decoration of the lamps often includes either the name or the symbol from Islamic heraldry of the donor, who usually gave a group of lamps.[7] Other types of lighting in mosques were large metal lamp stands, like very wide candlesticks, which were also used in secular buildings. These could be very intricately decorated.[8]
Oil lamps were introduced gradually into mosques and took time until they became common, which was around the end of the 7th century and the beginning of the 8th century.[9] They survive in considerable numbers from theMiddle Ages, especially the 13th and 14th centuries, withCairo in Egypt andAleppo andDamascus in Syria being the most important centers of production.[10]
The elaborate decorated types were mostly succeeded by plain glass oil lamps with a simple rim at the top, by which they were attached to (typically) a circular metal bar. Often these hang in tiers. Mosques today have shifted to a more cost efficient, energy saving method of lighting by converting mosque lamps to electric lighting techniques. In most cases Mosques will retain the hanging circular fittings, but use electric lights and glass shades of various sorts, not essentially different from other glasslampshades used in lighting other buildings. Some cases, such as the Ar-Rahmaniah Mosque at Kampung Pengkalan Baharu have also incorporated energy saving techniques such as solar panels to power mosque lighting.[11]

In 2000, three 14th-centuryMamluk mosque lamps in pristine condition from the collection ofBethsabée de Rothschild sold atChristie's in London for £1,763,750 (US$2,582K), £993,750 (US$1,455K) and £641,750 (US$937K).[12] Other mosque lamp collections are held at the Louvre museum in Paris and the Cairo Museum of Islamic Art.[13] In the second half of the 19th century, a number of forgeries, or expensive glass ornaments in the style of Mamluk lamps were produced in France and Italy.[14]
Light is often an important symbol in many religious texts, including the Qur'an.[9] Darkness to light is often interpreted as a transformation from un-enlightenment to enlightenment under the light which is often considered to be Allah.[9] Light can often be seen as or used in a way to become closer to God and this can be connected to the many lamps in mosques.[15]
:God is the Light of the heavens and the earth.
- The Parable of His Light is as if there were a Niche and within it a Lamp
- the Lamp enclosed in Glass: the glass as it were a brilliant star
- Lit from a blessed Tree, an Olive, neither of the east nor of the West,
- whose oil is well-nigh luminous, though fire scarce touched it
- Light upon Light! God doth guide whom He will to His Light
- God doth set forth Parables for men: and God doth know all things.
At times mosque lamps were used in rituals duringRamadan. In one such ritual, the flame of the lamp would be extinguished to signal to people that prayer was about to start.[9] In big mosques it was common to see thousands of lamps being used to illuminate the space.[17]

A miniature in theSister Hagaddah, produced in 14th-century Spain and now in theBritish Library, showing a service in asynagogue has lamps with the same form as Islamic ones.
