Oil lamp

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, a ritual seven-branched oil lamp used in the Second Temple, forms the centre of the Chanukah story.

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 (Greek: kandili, Church Slavonic: lampada) are still used both on the Holy Table (altar) and to illuminate icons 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.

Oil lamps are commonly used in Hindu temples 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 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.

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.

The first manufactured red pottery oil lamps appeared in the Chalcolithic. These were of the round bowl type.

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.

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.[4][5]

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.

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.

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.[6] 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.

Seal oil lamps

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 and other Inuit peoples.[7]

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 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.[8]

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

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.

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.[9][10]

Terracotta lamp

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 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.

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.[11]

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 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.

In 9th-century Baghdad, al-Razi (Rhazes) described the first kerosene lamp; he referred to it as the Arabic: naffatah in his Kitab al-Asrar ('Book of Secrets').[12]

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

Oil burning carriage lamps provided a model for the first bicycle lamps in the 1860s.[13]

• Jerusalem oil lamp: The clay has a characteristic black color because it was burned without oxygen. Usually of high quality.
• Daroma oil lamp
• Jerash oil lamp
• Nabatean oil lamp
• Herodian oil lamp: Considered to be used mainly by Jews. Wheel-made, rounded, and have a nozzle with concave sides. The lamps are usually not decorated; if there is decoration, it tends to be simple. Very common throughout all of Palestine, and some lamps have also been found in Jordan. Date from the 1st century BC to the end of the 1st century AD.
• Menorah oil lamp, seven nozzles: Rare and are associated with Judaism because of the numerical connection with the seven branches or arms of the Menorah.
• Samaritan oil lamp: Characterized by a sealed filling hole, which was to be broken by the buyer. This was probably done to ensure ritual purity. They have a wider spout, and the concavities flanking the nozzle are almost always emphasized with a ladder pattern band. In general, the lamps are uncoated. The decorations are linear or geometric.
  • Type I: A distinct channel runs from the pouring hole to the nozzle. They have a small knob handle, a ladder pattern around the nozzle and no ornamentation on the bottom of the base.
  • Type II: Pear-shaped and elongated, with a lined channel that extends from the filling hole to the nozzle. Continued to be used up to the early Muslim period.
• Candle Stick oil lamp: Menorah design on the nozzle and bunch of grapes on the shoulders.
• Byzantine oil lamp: The upper parts and their handles are covered with braided patterns. All are made of a dark orange-red clay. A rounded bottom with a distinct X or cross appears inside the circled base.
• Early Islamic oil lamp: Large knob handle and the channel above the nozzle are the dominant elements of these. The handle is tongue-shaped, and decoration is rich and elegant. The lower parts are extremely broad and the nozzles are pointed.

Lamps in a temple at Wayanad, Kerala, India

A basic earthen oil lamp used for Diwali

In 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 Deep Daan, the gift of a lamp was and still is believed to be the best 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 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 amavasya (moonless) day in the month of 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 – "tamaso ma jyotirgamaya".

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 matsya ('fish'), 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 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 deepastambhas ('towers of light') were created.

Lighting of a Kuthuvilakku

Erecting a 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 Kamba Vilakku can be seen. To adapt the design to households and smaller spaces, the deepavriksha ('tree of light') was created. As the name suggests, it is a metal lamp container with curvi-linear lines branching out from the base, each holding a lamp. The Deepalakshmi is another common design, where the goddess Lakshmi holds the lamp in her hands. 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, "Chiraag tale andhera", 'the [utmost] darkness is under the oil-lamp (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).
