An '''oil lamp''' is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times. They work in the same way as a [[candle]] but with fuel that is liquid at room temperature, so that a container for the oil is required. A textile wick drops down into the oil, and is lit at the end, burning the oil as it is drawn up the wick.

Oil lamps are a form of [[lighting]], and were used as an alternative to candles before the use of electric lights. Starting in 1780, the [[Argand lamp]] quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the [[kerosene lamp]] in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally [[Electrification|electrified]] and light bulbs could be used.

Sources of fuel for oil lamps include a wide variety of plants such as nuts ([[walnuts]], [[almonds]] and [[kukui]]) and seeds ([[sesame]], [[Olive oil|olive]], [[Castor oil|castor]], or [[Flax oil|flax]]). Also widely used were animal fats (butter, [[ghee]], fish oil, [[Shark liver oil|shark liver]], [[whale blubber]], or [[Seal oil|seal]]). [[Camphine]], made of purified spirits of [[turpentine]], and burning fluid, a mixture of turpentine and alcohol, were sold as lamp fuels starting in the 1830s as the [[whale oil]] industry declined. Sales of both camphene and burning fluid decreased in the late 1800s as other sources of lighting, such as [[kerosene]] made from petroleum, [[gas lighting]] and [[electric lighting]], began to predominate.

Most modern lamps (such as [[Lantern#Modern lanterns|fueled lanterns]]) have been replaced by [[Propane|gas-based]] or [[Naphtha#Other applications|petroleum-based]] fuels to operate when emergency non-electric light is required. Oil lamps are currently used primarily for their ambience.

==Components==
[[Image:Oil lamp Fandaqomiyah.jpg|thumb|Double-nozzled [[terracotta]] oil lamp found in [[Samaria]]]]

The following are the main external parts of a [[terra-cotta]] lamp:
; Shoulder
; Pouring hole
: The hole through which fuel is put inside the fuel chamber. The width generally ranges from {{cvt|0.5|–|5|cm|in|1}}. There may be one hole or multiple holes.
; Wick hole and the nozzle
: May be either an opening in the body of the lamp or an elongated nozzle. In some specific types of lamps, there is a groove on the top of the nozzle that runs along to the pouring hole to re-collect the oozing oil from the wick.
; Handle
: Lamps can come with a handle. The handle can come in different shapes. The most common is a ring-shaped for the forefinger surmounted by a [[palmette]], on which the thumb is pressed to stabilize the lamp. Other handles can be crescent-shaped, triangular, or oval-shaped. The handleless lamps usually have an elongated nozzle, and sometimes have a [[Lug (knob)|lug]] rising diagonally from the periphery. The lug may act as a small handle where the thumb rests. Some lugs are pierced. It was speculated that pierced lugs were used to place a pen or straw, called the {{langx|la|acus}} or {{lang|la|festuca}}, with which the wick was trimmed. Others think that the pierced lugs were used to hang the lamp on a metal hook when not in use.{{citation needed|date=September 2015}}
; Discus
; Fuel chamber
: The fuel reservoir. The mean volume in a typical terra-cotta lamp is {{cvt|20|cc|mL}}.{{citation needed|date=September 2015}}

==Types==
Lamps can be categorized based on different criteria, including material ([[clay]], [[silver]], [[bronze]], [[gold]], [[Rock (geology)|stone]], [[Slip (ceramics)|slip]]), shape, structure, design, and imagery (e.g. symbolic, religious, mythological, erotic, battles, hunting).

Typologically, lamps of the [[Ancient Mediterranean]] can be divided into seven major categories:

; [[Potter's wheel|Wheel-made]]: This category includes Greek and Egyptian lamps that date before the 3rd century BC. They are characterized by simplicity, with little or no decoration, a wide pour-hole, a lack of handles, and a pierced or unpierced [[Lug (knob)|lug]]. Pierced lugs occurred briefly between the 4th and 3rd century BC. Unpierced lugs continued until the 1st century BC.

; Volute, Early Imperial: With spiral, scroll-like ornaments called [[volute]]s extending from their nozzles, these lamps were predominantly produced in Italy during the [[History of the Roman Empire#27 BC–AD 14: Augustus|Early Roman]] period. They have a wide discus, a narrow shoulder, no handle, elaborate imagery and artistic finishing, and a wide range of patterns of decoration.

; High Imperial: These lamps are late Roman. The shoulder is wider and the discus is smaller with fewer decorations. These lamps have handles, short, plain nozzles, and less artistic finishing.

; Frog: This is a regional style lamp exclusively produced in [[Egypt]] and found in the regions around it, between {{circa|100}} and 300 AD. The [[frog]] ([[Heqet]]) is an Egyptian fertility symbol.

; [[African Red Slip]]: Lamps made in North Africa, but widely exported, decorated in a red slip. They date from the 2nd to the 7th century AD and comprise a wide variety of shapes including a flat, heavily decorated shoulder with a small and relatively shallow discus. Their decoration is either non-religious, [[Christianity|Christian]] or [[Jewish]]. Grooves run from the nozzle back to the pouring hole. It is hypothesized{{by whom|date=September 2015}} that this is to take back spilled oil. These lamps often have more than one pour-hole.

; Slipper: These lamps are oval-shaped and found mainly in the [[Levant]]. They were produced between the 3rd to 9th centuries AD. Decorations include vine scrolls, palm wreaths, and [[Greek letters]].

; Factory lamps: Also called {{langx|de|Firmalampen}}, these are universal in distribution and simple in appearance. They have a channeled nozzle, plain discus, and two or three bumps on the shoulder. Initially made in factories in [[Northern Italy]] and Southern [[Gaul]] between the 1st and 3rd centuries AD, they were exported to all Roman provinces. The vast majority were stamped on the bottom to identify the manufacturer.{{citation needed|date=August 2020}}

==In religious contexts==

===Judaism===
[[Image:Three Oil Jews lamps from Sardegna MUSEO NAZIONA SANNA SASSARI.jpg|thumb|Jewish [[terracotta]] oil lamps from [[Sardinia]] in the Museo Nazionale Sanna, Sassari]]

Lamps appear in the Torah and other Jewish sources as a symbol of "lighting" the way for the righteous, the wise, and for love and other positive values. While fire was often described as being destructive, light was given a positive spiritual meaning. The oil lamp and its light were important household items, and this may explain their symbolism. Oil lamps were used for many spiritual rituals.
The oil lamp and its light also became important ritualistic articles with the further development of Jewish culture and religion. The Temple [[Menorah (Temple)|Menorah]], a ritual seven-branched oil lamp used in the [[Second Temple]], forms the centre of the [[Chanukah]] story.

===Christianity===<!-- [[Lampada]] redirects here -->
[[File:Saint Mercurius, bishop of Smolensk.jpg|thumb|Oil lamp burning before the [[icon]] of St. Mercurius of Smolensk, [[Kyiv Pechersk Lavra]], [[Ukraine]]]]

There are several references to oil lamps in the [[New Testament]]. In the [[Eastern Orthodox Church]], [[Roman Catholic Church]], and [[Eastern Catholic Churches]] oil lamps ({{langx|el|kandili}}, {{langx|cu|lampada}}) are still used both on the [[Holy Table]] (altar) and to illuminate [[icon]]s on the [[iconostasis]] and around the [[temple]] (church building). Orthodox Christians will also use oil lamps in their homes to illuminate their [[icon corner]]. Traditionally, the [[sanctuary lamp]] in an Orthodox church is an oil lamp. It is lit by the [[bishop]] when the church is [[consecrated]], and ideally it should burn perpetually thereafter. The oil burned in all of these lamps is traditionally [[olive oil]]. Oil lamps are also referenced as a symbol throughout the New Testament, including in the [[Parable of the Ten Virgins]].

[[File:Paavai-vilakku8.JPG|thumb|upright=.5|left|{{lang|ta-Latn|Paavai vilakku}}: brass oil lamp from [[Tamil Nadu]] in the image of [[Andal]]]]

Oil lamps are commonly used in [[Hindu temple]]s as well as in home shrines. Generally the lamps used in temples are circular with places for five wicks. They are made of metal and either suspended on a chain or screwed onto a pedestal. There will usually be at least one lamp in each shrine, and the main shrine may contain several. Usually only one wick is lit, with all five burning only on festive occasions. The oil lamp is used in the Hindu ritual of [[Aarti]].

In the home shrine, the style of lamp is usually different, containing only one wick. There is usually a piece of metal that forms the back of the lamp, which has a picture of a [[Hindu deity]] embossed on it. In many houses, the lamp burns all day, but in other homes, it is lit at sundown. The lamp in the home shrine is supposed to be lit before any other lights are turned on at night.

A hand-held oil lamp or [[incense sticks]] (lit from the lamp) are also used during the Hindu [[Puja (Hinduism)|puja]] ceremony. In the North of India, a five-wick lamp is used, usually fueled with [[ghee]]. On special occasions, various other lamps may be used for puja, the most elaborate having several tiers of wicks.

In [[South India]], there are a few types of oil lamps that are common in temples and traditional rituals. Some of the smaller ones are used for offerings as well.

They have only one wick.

When the [[Brihadeeswarar Temple|Big Temple]] in [[Thanjavur, Tamil Nadu]], was built 1010 AD, there were elaborate measures taken to provide lighting for the temple. Lands were donated to or conquered for the temple for this sole objective. The income from these lands would go towards providing the oil for the lights.<ref>{{cite book|url=https://books.google.com/books?id=O1b1N_Dx0jsC&pg=PA87|title=The Royal Temple of Rajaraja: An Instrument of Imperial Cola Power|first=Geeta|last=Vasudevan|year=2003|publisher=Abhinav Publications|isbn=8170173833}}</ref>

===Chinese===
[[Image:Malaysian god shrine.jpg|thumb|upright|right|Traditional Chinese shrine in [[Petaling Jaya]], [[Malaysia]], containing an oil lamp]]
Oil lamps are lit at traditional Chinese shrines before either an image of a deity or a plaque with [[Classical Chinese]] characters giving the name of the deity. Such lamps are usually made from clear glass (giving them a similar appearance to normal drinking glasses) and are filled with oil, sometimes with water underneath. A cork or plastic floater containing a wick is placed on top of the oil with the bottom of the wick submerged in the oil.

Such lamps are kept burning in shrines, whether private or public, and incense sticks or [[joss sticks]] are lit from the lamp.

==History==
{{More citations needed section|date=January 2012}}
Curved stone lamps were found in places dated to the [[10th millennium BC]] ([[Mesolithic]], [[Middle Stone Age]] Period, c. 10,300–8000 BC). The oldest stone-oil lamp was found in [[Lascaux]] in 1940 in a cave that was inhabited 10,000 to 15,000 years ago.<ref>{{cite web|url=http://www.epalladioartworkshop.com/OILLAMPS/HISTORY/index.htm|website=Epalladio Art Workshop|last=Papatzanakis|first=Noufris|title=Ancient Oil Lamps History|year=2012}}</ref><ref>{{cite web|url=https://archeologie.culture.fr/lascaux/en/lighting|title=Parietal art: Lighting|website=Lascaux|publisher=Musée d'Archéologie nationale|access-date=2020-08-07|url-status=live|archive-url=https://web.archive.org/web/20200808000035/https://archeologie.culture.fr/lascaux/en/lighting|archive-date=2020-08-08}}</ref>

[[File:千灯馆新石器时代石灯.jpg|thumb|Neolithic stone lamps in the Thousand Lamp Museum in [[Qiandeng]], [[Kunshan]], [[Suzhou, Jiangsu|Suzhou]]]]
Some archaeologists claim that the first shell-lamps existed more than 6,000 years ago ([[Neolithic]], [[Later Stone Age]], c. 8500–4500 BC). They believe that the alabaster shell-shaped lamps dug up in [[Sumer]]ian sites dating to 2600 BC were imitations of real shell-lamps that had been used for a long time ([[Early Bronze Age]], [[Canaan]]ite/[[Bronze Age|Bronze I–IV]], c. 3300–2000 BC).

It is generally agreed that the evolution of handmade lamps moved from bowl-shaped to saucer-shaped, then from saucer with a nozzle, to a closed bowl with a spout.{{Citation needed|date=July 2019}}

=== Chalcolithic Age (4500–3300 BC) ===
The first manufactured red pottery oil lamps appeared in the [[Chalcolithic]]. These were of the round bowl type.

=== Bronze Age (3200–1200 BC) ===
Bronze Age lamps were simple wheel-made bowls with a slight pinch on four sides for the wick. Later lamps had only one pinch. These lamps vary in the shape of the rim, the general shape of the bowl and the shape of the base.

====Intermediate Bronze Age (EBIV/MBI)====
A design with four spouts for wicks appeared in the Intermediate Bronze Age (2300-2000 BC). Lamps are made from large bowls with flattened bases for stability, and four equally spaced shallow pinches in the rim for wicks, although some lamps with only a single pinch have also been found. The four-spout design evolved to provide sufficient light when fueled with fish or animal oils, which burn less efficiently than olive oil.<ref>{{cite journal|last=Herriott|first=Conn|editor-last1=Ilan|editor-first1=David|editor-last2=Shapira|editor-first2=Hananel|editor-last3=Feinberg-Vamosh|editor-first3=Miriam|url=https://www.researchgate.net/publication/305381378|title=Artifacts from the Intermediate Bronze Age Tombs|journal=NGSBA Archaeology|volume=3|date=January 2015|pages=112–120|publisher=[[Hebrew Union College]]|format=PDF}}</ref><ref>{{cite web |last1=Douglas |first1=David A. |title=The Development and Demise of the Early Bronze Age Near Eastern Oil lamp, 2300 - 2000 B.C.E. |url=https://sites.google.com/site/earlyoillamps/the-early-bronze-age-iv-oil-lamp |website=Perspective on Ancient Near Eastern Oil Lamps |access-date=25 February 2021}}</ref>

====Middle Bronze Age lamps (MB)====
The four-wick oil lamps persist into this period. However, most lamps now have only one wick. Early in this period the pinch is shallow, while later on it becomes more prominent and the mouth protrudes from the lamp's body. The bases are simple and flat. The crude [[potter's wheel]] is introduced, transforming the handmade bowls to a more uniform container. The saucer style evolves into a single spout shape.

====Late Bronze Age lamps (LB)====
A more pronounced, deeper single spout is developed, and it is almost closed on the sides. The shape is evolving to be more triangular, deeper and larger. All lamps are now wheel-made, with simple and usually flat bases.

===Iron Age (1200–560 BC)===
During the [[Iron Age]], lamp rims become wider and flatter, with a deeper and higher spout. The tip of the spout is more upright in contrast to the rest of the rim.<ref>{{cite journal|last1=Biran|first1=A.|last2=Gopna|first2=R.|title=An Iron Age Burial Cave at Tel Ḥalif|year=1970|journal=Israel Exploration Journal|publisher=Israel Exploration Society|volume=20|number=3|pages=156–169|jstor=27925230}}</ref> The lamps are becoming variable in shape and distribution, although some remain similar to lamps from the Late Bronze period. In addition, other forms evolve, such as small lamps with a flat base and larger lamps with a round base. The later form continues into the [[Iron Age II]].

In the later Iron Age, variant forms appear. One common type is small, with a wide rim and a wide base. Another type is a small, shallow bowl with a thick and high discus base.

===Arctic===
[[File:Descriptive booklet on the Alaska historical museum (1922) (14758775556).jpg|thumb|Seal oil lamps]]
{{See also|Qulliq}}
The ''[[qulliq]]'' (seal-oil lamp) provided warmth and light in the harsh Arctic environment where there was no wood and where the sparse population relied almost entirely on seal oil. This lamp was the most important article of furniture for the [[Inuit]], [[Yupik peoples|Yupik]] and other [[Inuit]] peoples.<ref>{{cite book|last1=Joyce|first1=Thomas Athol|last2=Dalton|first2=Ormonde Maddock|year=1910|title=Handbook to the ethnographical collections|url=https://archive.org/details/handbooktoethnog00brit|chapter=The Eskimo|chapter-url=https://archive.org/stream/handbooktoethnog00brit/handbooktoethnog00brit#page/248/mode/2up|publisher=Oxford University Press|location=Oxford|page=249|via=Internet Archive}}</ref>

The lamps were made of stone and their sizes and shapes of lamps could be different, but mostly were elliptical or half-moon shaped. The wicks were mostly made of dried moss or [[Eriophorum callitrix|cottongrass]] and were lit along the edge of the lamp. A slab of seal blubber could be left to melt over the lamp feeding it with more fat.<ref>{{cite book|title=Brilliant: The Evolution of Artificial Light|last=Brox|first=Jane|url=https://books.google.com/books?id=ma_qDwAAQBAJ|chapter=New Century, Last Flame|chapter-url=http://www.ralphmag.org/GD/eskimo-reading.html|via=ralphmag.org|publisher=Houghton Mifflin Harcourt|date=2010-06-29|isbn=978-0547487151|archive-url=https://web.archive.org/web/20200125191848/http://www.ralphmag.org/GD/eskimo-reading.html|archive-date=2020-01-25}}</ref>

===Persian===
Persian lamps were large, with thin sides and a deep pinch that flattens the mouth and makes it protrude outward.

===Greek===
Greek lamps are more closed to avoid spilling. They are smaller and more refined. Most are handle-less. Some are with a lug, which may be pierced or not pierced. The nozzle is elongated. The rim is folded over so it overlaps in order to make the nozzle, and is then pinched to make the wick hole.

They are round in shape and wheel-made.

===Chinese===
The earliest Chinese oil lamps are dated from the [[Warring States period]] (481–221 BC). The ancient Chinese created oil lamps with a refillable reservoir and a fibrous wick, giving the lamp a controlled flame. Lamps were constructed from [[jade]], bronze, ceramic, wood, stone, and other materials. The largest oil lamp excavated so far is one discovered in a 4th-century tomb located in modern Pingshan, Hebei.<ref name="Metropolitan">{{cite book|title=China: Dawn of a Golden Age, 200-750 AD|url=https://archive.org/details/bub_gb_JbdS-R3y72MC|year=2004|publisher=Metropolitan Museum of Art|isbn=978-1-58839-126-1|pages=182–183}}</ref><ref>{{Cite book|title=Austere Luminosity of Chinese Classical Furniture|last=Handler|first=Sarah|publisher= University of California Press|year=2001|isbn=978-0520214842|publication-date=October 1, 2001|pages=308–309}}</ref>

===Early Roman===
[[File:Terracotta_lamp_MET_DP869.jpg|thumb|Terracotta lamp]]
[[Image:Oil Lamp J 1.jpg|thumb|A terracotta oil lamp of the Roman Imperial era (replica)]]

Production of oil lamps shifted to Italy as the main source of supply in the Early Roman era. Molds began to be used, and lamps were produced in large scale in factories. All lamps are closed in type. The lamp is produced in two parts, the upper part with the spout and the lower part with the fuel chamber. Most are of the characteristic "Imperial Type"—round, with nozzles of different forms (volute, semi-volute, U-shaped), a closed body, a central disk decorated with reliefs and a filling hole.

===Late Roman===
Late Roman lamps were of the "High Imperial" type. They included more decorations, and were produced locally or imported in large scale. The multiple-nozzled lamps appeared during this period. Many different varieties were created.

Frog type lamps also appeared during this period. These are kidney-shaped, heart-shaped or oval, and feature the motif of a frog or its abstraction, and sometimes geometrical motifs. They were produced around 100 AD. They are so variant that two identical lamps are seldom found.

===Late Middle Age===
[[File:Late-antique-oil-lamp.jpg|thumb|A late antique oil lamp showing a human figure identified as Christ.]]
Early Christian and late antique oil lamps were diverse. One of the most notable ones were Mediterranean sigillata (“African”) lamps. The motifs were largely geometric, vegetative and graphic (monograms), with figural depiction of animals and human figures, often Christ.<ref>{{cite journal |last1=Jukić Buča |first1=Vendi |date=2016 |title= Lamps from the upper layers of a site in Pula's St Theodore's quarter |url=https://www.bib.irb.hr/846562?rad=846562 |journal=Histria archaeologica: časopis Arheološkog muzeja Istre |volume=46/2015 |pages=169–194 }}</ref> Those depicting Christ or the Chi Rho often categorized as Hayes Type II.

===Byzantine===
Oil lanterns of the Byzantine were slipper-shaped and highly decorative. The multiple-nozzle design continued and most lamps bore handles. Some have complex exteriors.

===Early Islamic===
[[Image:Beja51.jpg|thumb|Early Islamic oil lamps (11th century), found in Southern Portugal]]

There is a transition period from Byzantine to Islamic lamps. The decoration on lamps of this transition period changed from crosses, animals, human likenesses, birds, or fish to plain linear, geometric, and raised-dot patterns.

The early Islamic lamps continued the traditions of Byzantine lamps. Decorations were initially a stylized form of a bird, grain, tree, plant, or flower. Later, they became entirely geometric or linear with raised dots.

An early description of the [[kerosene lamp]] comes from 9th-century [[Baghdad]] by [[Muhammad ibn Zakariya al-Razi|al-Razi]] (Rhazes). He referred to it as the {{langx|ar-Latn|naffatah}} in his {{lang|ar-Latn|Kitab al-Asrar}} ('Book of Secrets').<ref>{{cite magazine|first=Zayn|last=Bilkadi|others=Illustrated by Bob Lapsley|title=The Oil Weapons|url=https://archive.aramcoworld.com/issue/199501/the.oil.weapons.htm|magazine=[[Saudi Aramco World]]|date=January 1995|volume=46|number=1|pages=20–27}}</ref>

In the transition period, some lamps had Arabic writing. Writing later disappears until the [[Mamluk]] period (13th to 15th century AD).

=== Industrial age ===
Oil burning carriage lamps provided a model for the first [[bicycle lamp]]s in the 1860s.<ref>{{cite book|last1=Clemitson|first1=Suze|title=A History of Cycling in 100 Objects|url=https://books.google.com/books?id=6IHDDgAAQBAJ|location=London|publisher=Bloomsbury Publishing|date=2017|page=114|isbn=9781472918901|access-date=2018-04-22|quote=The first bicycle lamps from the 1860s were based on oil-burning carriage lanterns.}}</ref>

[[Image:Diya.jpg|thumb|A basic earthen oil lamp used for [[Diwali]]]]

In [[Vedic period|Vedic times]], fire was kept alive in every household in some form and carried with oneself while migrating to new locations. Later, the presence of fire in the household or a religious building was ensured by an oil lamp. Over the years various rituals and customs were woven around an oil lamp.

For {{lang|sa-Latn|Deep Daan}}, the gift of a lamp was and still is believed to be the best {{lang|hi-Latn|daan}} ('donation'). During marriages, spinsters of the household stand behind the bride and groom, holding an oil lamp to ward off evil. The presence of an oil lamp is an important aspect of ritual worship (the {{lang|sa-Latn|Shodashopachar Puja}}) offered to a deity. Moreover, a day is kept aside for the worship of the lamp in the busy festival calendar, on one {{lang|sa-Latn|amavasya}} (moonless) day in the month of [[Shravana (month)|Shravan]]. This reverence for the deep is based on the symbolism of the journey from darkness and ignorance to light and the knowledge of the ultimate reality – "{{lang|sa-Latn|tamaso ma jyotirgamaya}}".<ref>{{Cite book |last=Olivelle |first=Patrick |url=https://books.google.com/books?id=f9-2jV7sRuEC&pg=PR9 |title=Upaniṣads |date=1998 |publisher=Oxford University Press |isbn=978-0-19-283576-5 |pages=12–13 |language=en}}</ref>

Earlier lamps were made out of stone or seashells. The shape was like a circular bowl with a protruding beak. Later, they were replaced by earthen and metal lamps. In the epics ''[[Ramayana]]'' and ''[[Mahabharata]]'', there are references to gold and silver lamps as well. The simple shape evolved and the lamps were created in the shapes of the {{lang|hi-Latn|matsya}} ('fish'), {{lang|hi-Latn|kurma}} ('tortoise') and other incarnations of god [[Vishnu]]. Lamps were also created in the shape of the many emblems of gods, like [[conch]] shells or [[lotus flower|lotuses]]. Birds such as swans, peacocks, or parrots, and animals like snakes, lions, elephants and horses were also favorites when decorating a lamp. For lighting multiple lamps, wooden and stone {{lang|hi-Latn|deepastambhas}} ('towers of light') were created.

Erecting a {{lang|hi-Latn|deepastambha}} in front of a temple is still a general practice in western and southern India. In some of the South Indian temples, raised brass lamp towers called {{lang|hi-Latn|Kamba Vilakku}} can be seen. To adapt the design to households and smaller spaces, the {{lang|hi-Latn|deepavriksha}} ('tree of light') was created. As the name suggests, it is a metal lamp container with curvi-linear{{Vague|reason=unknown meaning|date=August 2020}} lines branching out from the base, each holding a lamp. The {{lang|hi-Latn|Deepalakshmi}} is another common design, where the goddess Lakshmi holds the lamp in her hands. {{lang|hi-Latn|Kuthuvilakku}} is another typical lamp traditionally used for household purposes in South India.

Oil lamps also were included in [[proverbs]]. For example, a Bradj (pre-Hindi) proverb says, "{{lang|gu-Latn|Chiraag tale andhera}}", 'the [utmost] darkness is under the oil-lamp ({{lang|gu-Latn|chiraag}})', meaning that what you seek could be close but unnoticed (right under your nose or feet), in various senses (a lamp's container casts a strong shadow).
