The Gundestrup cauldron is a beautifully decorated silver container believed to have been made between 200 BC and 300 AD, or more specifically between 150 BC and 1 BC. This places it in the late La Tène period or the early Roman Iron Age. It is the largest known example of European Iron Age silver craftsmanship, with a diameter of 69 cm (27 in) and a height of 42 cm (17 in). The cauldron was discovered in pieces in 1891 in a peat bog near the village of Gundestrup in the Aars parish of Himmerland, Denmark. It is now displayed at the National Museum of Denmark in Copenhagen, with replicas shown in other museums. It was also part of a traveling exhibition called The Celts in the UK from 2015 to 2016.
The cauldron is not complete. It consists of a rounded cup-shaped base, five interior plates, and seven exterior plates. A missing eighth exterior plate would have completed the circle, and only two sections of the rim at the top remain. The base plate is mostly smooth and undecorated, except for a decorated round medallion in the center of the interior. All other plates are heavily decorated using repoussé work, a technique where silver is hammered from beneath to create raised designs. Additional details were added using gilding and inlaid glass for the eyes of figures. Other metal fittings were also found. The cauldron weighs just under 9 kilograms (20 lb).
Although the cauldron was found in Denmark, it was likely not made there. It includes artistic and technical elements from Gaulish and Thracian cultures, such as specific styles of decoration and imagery. The design of the panels closely resembles Thracian silverwork, while the depictions of human figures are similar to those found in Celtic art. However, connecting the scenes directly to Celtic mythology remains a topic of debate. Some symbols also appear to be inspired by the Near East.
Large-scale hospitality was likely a duty for Celtic leaders, and cauldrons were important items of prestige. However, most cauldrons from this time were simpler and smaller. The Gundestrup cauldron is unusually large and detailed, with no close match except for a large fragment of a bronze cauldron found in Denmark at Rynkeby. The wet, waterlogged conditions in parts of Scandinavia have preserved many unique objects that might have otherwise been lost. Scholars have studied the cauldron extensively, and it shows how European art combined influences from different cultures. While the exact meaning of its designs may never be fully understood, the cauldron remains a remarkable example of ancient craftsmanship.
Discovery
The Gundestrup cauldron was found by people cutting peat in a small peat bog named "Rævemose," which is near a larger bog called "Borremose," on May 28, 1891. The Danish government gave the finders a large reward, but they later argued loudly about how to divide it. Studies of the peat bog at the time showed that the land had been dry when the cauldron was placed there, and over time, peat grew over it. The way the pieces were stacked suggests someone tried to hide the cauldron well. Another study of Rævemose in 2002 concluded that the peat bog may have existed when the cauldron was buried.
The cauldron was discovered in a broken state, with five long rectangular plates, seven short plates, one round plate (called the "base plate"), and two pieces of tubing inside the curved base. There is also a piece of iron from a ring that was originally placed inside the silver tubes along the edge of the cauldron. It is believed that one of the eight short plates is missing because the total size of the seven outer plates is smaller than the size of the five inner plates.
Carefully made full-size copies of the cauldron have been created. One is in the National Museum of Ireland, and several are in France, including the Musée gallo-romain de Fourvière in Lyon and the Musée d'archéologie nationale in Saint-Germain-en-Laye.
Reconstruction
The cauldron was discovered in broken pieces, so it needed to be put back together. Sophus Müller, the first person to study the cauldron, figured out the traditional order of the plates. He used the positions of solder marks found around the edge of the bowl. In two instances, a hole that goes through both the inner and outer plates also helped determine the order. When the plates were fully reconstructed, they alternate between images of females and males, assuming the missing eighth plate shows a female.
Not all experts agree with Müller’s arrangement. Timothy Taylor noted that, except for the two cases with holes, the order of the plates cannot be confirmed by looking at the solder positions. He explained that the plates are not next to each other but are separated by a 2 cm space. This makes it hard to be certain about the correct sequence, even if a story or message exists. However, Larsen’s research supported the order of the inner plates as determined by Müller, Klindt-Jensen, and Olmsted. He also found that the order of the outer plates is confirmed by the placement of rivet holes, solder positions, and scrape marks.
Metallurgy
The Gundestrup cauldron is mostly made of silver, but it also includes gold for decoration, tin for joining parts together, and glass for the eyes of the figures. Studies show that the materials were added at different times, meaning the cauldron was created by artisans over many years. Many repairs were made to the cauldron, but these repairs are not as well done as the original work.
Silver was not often used in Celtic art, especially not in such large amounts. Usually, gold or bronze was preferred for important metal items, except for small jewelry. At the time the cauldron was made, silver was obtained by heating lead and silver ores to separate the silver.
By comparing the lead isotope levels in the silver to those used by other cultures, scientists believe the silver came from several ore sources, mostly in northern France and western Germany before the Roman period. Lead isotope studies also suggest that the silver used for the plates was melted and reused multiple times. Three to six different batches of recycled silver may have been used to make the cauldron. The circular "base plate" might have originally been a type of disc called a phalera. It is thought to have been added later to fix a hole in the bowl. Another idea is that the phalera was part of the decorations on a wooden cover, not the bowl itself.
The gold used for decoration can be divided into two groups based on purity and the amounts of silver and copper it contains. The less pure gold, which is thicker, was likely added later because thinner, purer gold sticks better to silver. Overall, the gold does not adhere well to the cauldron. The absence of mercury in the gold suggests that a method involving fire (fire-gilding) was not used. Instead, the gold was probably applied using mechanical tools, which explains the presence of closely spaced punch marks on the gilded areas.
Lead isotope analysis, similar to that used for silver, was also used for the tin. All the tin samples match the composition of tin from Cornwall, a region in western Britain. The tin used to join the plates and bowl together, as well as the glass eyes, is very pure and consistent in quality.
Finally, X-ray fluorescence tests showed that the glass in the cauldron is of a type called soda-lime. The glass contains elements found in calcareous sand and mineral soda, which are common on the east coast of the Mediterranean. These tests also indicate that the glass was made between the second century BC and the first century AD.
Flow of raw material
The manufacturing process had several steps that needed a lot of skill. Silver was melted in crucibles with copper to create a more subtle alloy. The melted silver was poured into flat ingots and then hammered into plates.
For the relief work, the silver sheets were heated to make them easier to shape into high relief. These rough shapes were filled with pitch from the back to make them firm for more detailed work with punches and tracers. The pitch was removed, and pattern areas were gilded. The eyes of larger figures were inlaid with glass. The plates were likely shaped flat first and then curved to be soldered together.
Most experts believe the Gundestrup cauldron was made by several silversmiths. Benner Larson used scanning electron microscopy to find 15 different punches on the plates, grouped into three tool sets. No single plate has marks from more than one group, matching earlier stylistic analysis that found at least three different silversmiths. The different purity and thickness of the silver also suggest work by multiple artisans.
Origins
The silverworking methods used to make the cauldron are not known from the Celtic world, but they match the famous Thracian tradition of shaping silver into sheets. The images on the cauldron are not clearly Thracian, but certain details, such as the way scenes are arranged, the decorative patterns, and specific items shown (like the shoelaces on the figure with antlers), help identify it as Thracian craftsmanship.
Taylor and Bergquist suggested that the Celtic tribe called the Scordisci hired Thracian silversmiths to create the cauldron. Classical historians record that the Cimbri, a Teutonic tribe, moved south from the lower Elbe region and attacked the Scordisci in 118 BC. After losing several battles to the Romans, the Cimbri withdrew north, possibly taking the cauldron with them to settle in Himmerland, where the cauldron was later discovered.
Olmsted (2001) noted that the art style of the Gundestrup cauldron matches that used in Armorican coins from 75–55 BCE, such as the billon coins made by the Coriosolites. This art style is unique to northwest Gaul and is mainly found between the Seine and Loire rivers, a region where the wealthy seafaring Veneti, as described by Caesar, held significant influence. This connection between the art style and the region supports the idea that the cauldron originated from this area.
The Gundestrup cauldron provides insight into a coin-driven art style, where the same skilled metalworkers who made large items like the cauldron also produced coins. It also shows cultural objects, such as swords, armor, and shields, that were common in this region, confirming the link between the art style and metal analysis. If, as Olmsted (2001) and Hachmann (1990) suggest, the Veneti also made silver phalerae found on the Isle of Sark and the Helden phalera, then many silver items like the Gundestrup cauldron likely came from northwest France, just before the Roman conquest.
Nielsen argues that focusing on the cauldron’s origin may lead to incorrect conclusions. Due to the movement of groups like the Celts and Teutons, and events like Roman expansion, it is unlikely that one group alone created the cauldron. Instead, the cauldron’s design and craftsmanship reflect a blending of cultures, with each influencing the others. Based on dating from beeswax found on the cauldron’s plates, Nielsen concluded it was made during the Roman Iron Age. However, an addendum to his article notes that results from the Leibniz Lab dated the beeswax about 400 years earlier than originally reported.
Ronald Hutton states that because the cauldron’s metals trace to the Black Sea region and it includes images of elephants, it should no longer be considered strictly Celtic.
Iconography
The decorated medallion on the round base plate shows a bull. Above the bull's back is a female figure holding a sword; three dogs are also shown, one above the bull's head and another near its hooves. It seems these figures are fighting; the third dog, located beneath the bull and near its tail, appears to be dead and is only slightly visible in the engraving. The bull may have been killed. Below the bull is ivy that is inspired by ancient Greek and Roman art. The bull's horns are missing, but there is a hole in the head where the horns were attached; perhaps they were made of gold. The bull's head rises completely above the plate, and the medallion is regarded as the most skillful part of the cauldron in terms of technique and art.
Each of the seven plates on the outside shows a face. Plates a, b, c, and d display bearded men, and the other three plates show women.
Interpretation and parallels
For many years, some scholars have studied the images on the cauldron by comparing them to the Celtic gods and stories found in later writings from the British Isles. Others are not sure about these interpretations. However, it is clear that some details on the cauldron match Iron Age Celtic artifacts found by archaeologists.
Other parts of the cauldron’s images are similar to art from the ancient Near East and have some connections to ancient India and Hindu gods and stories. Most scholars believe these designs were borrowed mainly for their visual appeal, not for their original meanings. However, some scholars have tried to link these images to traditions from the Proto-Indo-European religion.
One specific detail that is clearly Celtic is the group of carnyx players. The carnyx was a war horn described by the Romans and seen on Trajan’s Column. A few examples have been found by archaeologists, with more discovered in France in 2004.
Another detail that matches archaeology is the torc worn by several figures. This type of torc, called the "buffer" type, was a common Celtic artifact found in Western Europe, especially France, from the time the cauldron is thought to have been made.
Other details with possible Celtic links include the long swords carried by some figures, as well as horned or antlered helmets and boar crests on helmets. These items are similar to Celtic artifacts like a helmet with a raptor crest found in Romania, the Waterloo Helmet, and the Torrs Pony-cap and Horns. Shield bosses, spurs, and horse harnesses also match Celtic examples.
The antlered figure in plate A is often identified as Cernunnos, a god named on the 1st-century Gallo-Roman Pillar of the Boatmen. On that pillar, Cernunnos is shown as an antlered figure with torcs hanging from his antlers. Some believe the missing part of the figure on the cauldron might have shown him seated cross-legged, as described in other sources. Other cultures also had horned gods.
The figure holding the broken wheel in plate C is sometimes thought to be Taranis, a god associated with the sun or thunder, named by Lucian. Many wheels from the Iron Age seem to have been used as amulets.
The cauldron shows many animals, including elephants, dolphins, leopard-like felines, and fantastic creatures. It also includes animals common to Eurasia, such as snakes, cattle, deer, boars, and birds. While Celtic art often includes animals, it rarely shows them in magical or unusual forms with wings or mixed features. Exceptions exist, such as a boy riding a dolphin, borrowed from Greek art, and a ram-headed horned snake that appears three times on the cauldron. Art from Thrace and the Eurasian steppe also shows animals, and these styles helped spread designs between cultures.
On plate F, two figures standing beside a large head resemble a common motif in Assyrian and Persian art, including their long clothing. These figures are usually rulers, with wings symbolizing a deity protecting them. Other plates show griffins from Greek and Near Eastern art. Some large heads on the cauldron, likely gods, have small arms and hands, either holding animals or humans in a design similar to the "Master of Animals" motif.
Besides Cernunnos and Taranis, scholars do not agree on the identities of other figures. Some reject attempts to connect them to figures from distant or later sources. Some scholars suggest the elephants on plate B might reference Hannibal’s crossing of the Alps.
The double-headed wolfish monster attacking two fallen men on plate B could relate to Welsh or Irish characters like Manawydan or Manannán, a sea and Otherworld god. Another possibility is the Gaulish version of Apollo, who was a warrior and associated with healing.
Olmsted connects scenes on the cauldron to the Irish story Táin Bó Cuailnge. He suggests the antlered figure is Cú Chulainn, the bull is Donn Cuailnge, and the figures on plate E are Medb, Ailill, and Fergus. He also thinks the female figure on plate F might be Medb with her pets or Morrígan, a war goddess who takes bird forms. Olmsted sees Cernunnos as a Gaulish version of Cú Chulainn. He interprets scenes on plate A as related to the origins of the bulls in Táin Bó Cuailnge, which take on various animal forms.
Plate B might reflect a Gaulish version of the start of Táin Bó Cuailnge, where Medb circles her army for luck. Olmsted sees plate C as a Gaulish version of a scene where Cú Chulainn fights Morrígan.
Olmsted (1979) connects warriors on plate E to a scene from Táin Bó Cuailnge where Fraich and his men leap over a fallen tree and wrestle with Cu Chulainn. This scene is also linked to plate F, where Fraich’s body is taken to the underworld.
Both Olmsted and Taylor think the female figure on plate F might be Rhiannon from the Mabinogion, a goddess known for her birds. Taylor compares Rhiannon to Hariti, a figure from Bactrian mythology, and notes similarities between the female on plate B and the Hindu goddess Lakshmi, who is often shown with elephants. Wheel gods like Taranis and Vishnu also appear in multiple cultures.
