Who were the Celts?

5 June 2021

The early Celts rarely wrote about themselves. To the Greeks, they were known as Keltoi, Keltai or Galatai and to the Romans Celti, Celtae and Galli.

The first mention of the Celts was made by the Greeks authors between 540 and 424BC. But the most valuable insights are provided by Roman authors. As the Roman world was expanding, they came in direct contact with the Celts on their northern borders, however, these classical texts are incomplete as they were often copied long after the event. Therefore, the information we have provides, at best, an occasional 'snapshot' of the Celts.

It is believed that the Celts were a collection of tribes which originated in central Europe. Although separate tribes, they had similar culture, traditions, religious beliefs and language in common.

What did the Celts call themselves?

We don’t actually know what the Celts called themselves. The name ‘Celts’ is a modern name which is used to describe many tribes of people who lived during the Iron Age. None of the Classical texts refer to the peoples of Britain and Ireland as Celts. Therefore, as the Celts were a collection of tribes, they were more generally known by the name of those tribes or societies as opposed to a collective nation or empire.

Where did the Celts come from?

Coin of the Roman Republic

Early sources place Celts in western Europe and also occupying land near the headwaters of the Danube River. Their home territories have often been traced to central and eastern France, extending across southern Germany and into the Czech Republic.

In 279BC the Celts were known to have looted Delphi, the sacred Greek site. Strabo (Geographer) recorded a meeting between the Celts and Alexander the Great in 335BC in the Balkans. Classical writers had recorded a large-scale migration of Celts soon after 400BC, this migration took the Celts from central Europe into Northern Italy and Eastern Europe.

Celts in Britain

It is believed that the Celts arrived at the shores of Britain at approximately 1,000BC and lived there during the Iron Age, the Roman Age and the post Roman era. Their legacy continues today where examples of the language, culture and traditions continue to exist.

Welsh Celts

Today, Wales is seen as a Celtic nation. The Welsh Celtic identity is widely accepted and contributes to a wider modern national identity. During the 1st centuries BC and AD, however, it was specific tribes and leaders which were named. By the time of the Roman invasion of Britain, four tribal peoples occupied areas of modern day Wales:

  • Ordovices (north-west)
  • Deceangli (north-east)
  • Demetae (south-west)
  • Silures (south-east)

To understand how Celts first came to be associated with Wales, we must turn to the historical development of Celtic linguistics (the study of languages).

What languages did the Celts speak?

Archaeologia Britannica

Tracing the beginnings of Celtic languages is difficult. Most agree that they derive from an earlier language known as 'proto-Indo-European'. This probably reached western Europe through the movement of peoples, possibly from Central Asia between 6000 and 2000BC. Unfortunately, there is little agreement over precisely when this occurred and when and how Celtic languages subsequently developed.

On current understanding, Celtic languages have their origins at some time between 6000 and 600BC, with the earliest known inscriptions in a Celtic language being found in Northern Italy and dating to the 6th century BC. George Buchanon, a 16th-century scholar, suggested that the peoples of continental Europe had once spoken a related group of Gallic languages. Since modern Welsh, Irish and Scots Gaelic were similar to these ancient languages, the people of Britain, it was argued, originally came from France and Spain.

A pioneering study by Edward Lhuyd in 1707 recognised two families of Celtic languages, P-Celtic or Brythonic (Welsh, Breton, Cornish) and Q-Celtic or Goidelic (Irish, Scots Gaelic, Manx). The Brythonic languages were assumed to have come from Gaul (France), whilst the Goidelic languages were given an Iberian (Spain, Portugal) origin.

During the 18th century, people who spoke Celtic languages were seen as Celts. The ancient inhabitants of Wales, were therefore increasingly known as Celts.

Celtic Languages

The native tongue of Wales (known as Cymru by the Celts), is Welsh. Welsh is a Celtic language and is still widely spoken in Wales and across the world. In Cornwall some (although very few) still speak Corning, which is from the same linguistic strand as Welsh and Breton.

In Scotland, the Scots Gaelic is also still spoken, although by not as many as Welsh speakers. The local affiliate to the BBC in Scotland is known as BBC Alba, which is the Celtic name for the region. It is also worth noting that the origin of the Bagpipes, a famous musical instrument from Scotland can be traced to Celtic times as well.

What did the Celts look like?

Warriors fighting.

Looking again at the recordings by Roman literature, the Celts were described as wearing brightly coloured clothes, with some having used blue dye from the woad plant to paint patterns on their bodies.

What did the Celts wear?

They are known for their colourful wool clothing and later on the Scottish Tartan. The clothes the Celts would wear showed status and importance within the tribe. The usual Celtic attire would include a tunic and a belt, as well as a long cloak and trousers which were fastened by a ’fibuale’.

In fact, many historians have noted that the Celts were one of the first people in Europe to wear trousers, the ‘fibuale’ would be clasps, which were used to fasten their trousers.

What did the Celts eat?

There were obviously no supermarkets during the time of the Celts, they would grow their own plants, farm and hunt animals for food.

Their diet would include, wild foods such as mushrooms, berries, nettles, wild garlic and apples they would also eat spinach, onions, leeks, carrots and parsnips, blackberries, gooseberries and blueberries. Hazelnuts and walnuts as well as grains for bread and porridge would also feature in their diet.

As for meat, they would hunt deer, foxes, beavers, wild boars and bears as well as farm domesticated animals such as chickens, goats, sheep, pigs and cattle. They would also fish for Salmon, Trout or Mackerel. They would also eat eggs from hens and wild birds, along with insects and honey from bees.

More information about the food the Celts would eat during the Iron Age can be seen in our Daily life of the Celts learning resource.

Celtic Art and Archaeology

Detail of triskele

The appearance of a new style of art during the 5th century BC and its later spread across much of Europe has frequently been interpreted by archaeologists as evidence for a common Celtic culture or identity.

Celtic art was recognised and named by British scholars during the mid 19th century. However, it was not until 1910-14 that the earliest objects decorated in this style were traced to a common cultural area of north-east France, southern Germany and the Czech Republic.

It was named the La Tène culture , after an important collection of decorated metalwork discovered at a site on the edge of Lake Neuchâtel in Switzerland. The spread of La Tène or Celtic art across Europe, including Britain and Ireland, was for a long time interpreted as invasions by Celtic people.

More recently, British archaeologists have become increasingly dissatisfied with the idea of Celts invading Britain and of a 'Celtic' society sharing language, art, religious belief and identity. There is little conclusive evidence amongst the archaeological remains for large-scale arrivals of a new people from the Continent.

The archaeology of the Iron Age in Britain is suggesting a mosaic of regional societies, each with their own distinctive identity. This is at considerable odds with a uniform Celtic culture.

Archaeologists have also become more critical of their own assumptions when interpreting Iron Age sites. The presence of La Tène art in Wales need not indicate invading Celts, it could equally show the spread of a fashion across many societies or suggest long-distance exchange contacts. At the same time, we now know that much of the later La Tène art is distinctively British in style and largely absent in Continental Europe.

Debate has surrounded the notion of the Celts since scholars first began to examine it, and this discussion is set to continue.

It is possible that future genetic studies of ancient and modern human DNA may help to inform our understanding of the subject. However, early studies have, so far, tended to produce implausible conclusions from very small numbers of people and using outdated assumptions about linguistics and archaeology.

Ekeko - guarding memories

Sarah Younan, 1 June 2021

A long time ago an ancestor lived in the Congo, let’s call him Ekeko.

Ekeko the Spirit Doll

Ekeko was much loved by his community and after his passing, skilled craftsmen made a spirit doll from solid iron to guard his memory.

We don’t know exactly how this spirit doll found its way to Wales. It’s a gap in knowledge that speaks of colonialization and empire. Many artefacts were taken from the Congo, and with them cultural memories were lost. We are keen to hear from anyone who may know more about this spirit doll.

Often when artefacts end up in museum collections they can no longer serve their intended purpose. In order to try and activate Ekeko we worked together with Cruse Bereavement Care, Playframe and the Hands on Heritage project, a youth-led project at Amgueddfa Cymru funded through the National Heritage Lottery Fund. We worked with Norbert Mbu-Mputu, a Congolese philosopher and poet who created this poem:

I am Ekeko

Welcome to my home

Here in the space of Bakulu I guard memories

and connect the world of the seen and the unseen

I carry memories from the past, the present and the future.

 

Bakulu - a Space for Memories

To re-activate Ekeko, we created a photoscan of the spirit doll and built a virtual space, a Bakulu; a space to guard memories of the ancestors. We worked with young people supported by Cruse Bereavement care to add memories to this space. During workshops we explored virtual reality spaces, shared memories and created visual representations, from photographs, from clay, from images found online. We placed these in the virtual space, where Ekeko smiles as memories from the past and present are carried into the future.

You can view the 360 video of the virtual memory space we co-created.

 

Some tech stuff:

What is a photoscan?

Photoscanning also known as photogrammetry uses triangulation to create 3-dimensional representations of real life objects from photographs. By taking photographs from different angles, so-called "lines of sight" can be developed and the surface of the object can be calculated and rebuilt digitally.

How can I view the video?

You can view the video in 2D on Youtube, or you can create a 3D experience using your smartphone, some cardboard and the YouTube mobile app.

  1. Assemble Google Cardboard.

  2. Open the Ekeko video on YouTube app.

  3. To start playback, tap the play button.

  4. https://storage.googleapis.com/support-kms-prod/ED06541043D9B49799EFBF07A2966B453B34
    Tap the Cardboard icon . The screen split will split into two smaller screens.

  5. Insert your phone into Cardboard.

  6. Look around to view the video in VR180 or 360 degrees.

How can I navigate the video?

The memories will move slowly with enough time to allow you to read their captions. You can simply let the video play or navigate by:

  • In 2D using your mouse (or fingers if you are using touch screen) to grab the video image and move it around, and zoom in and out to navigate.

  • In 3D you can move your head to look around in the space.

  • You can pause the video for a closer look. The navigation remains active even if you pause the video.

 

With thanks to our participants, and the memories they kindly donated.

Grief is a natural process, but it can be devastating. Cruse Bereavement Care offer support after the death of someone close.

New resources for exploring nature and archaeology

Katherine Slade, 28 May 2021

Over the past year, we have all had to stay closer to home more often. We may have discovered new local places, and started to look in more detail at familiar places. The museum has launched a new set of web-based resources to help people continue this exploration. The new On Your Doorstep webpages help and encourage others to discover local archaeology and nature in Wales. We’ve included activities for investigating and learning more, in the countryside and urban areas. If you want to delve even deeper, you can explore our natural history and archaeology collections of over 4 million specimens, and find links to our specialist sites.

Visit: On Your Doorstep: Nature, geology and archaeology in Wales

Nature Bingo

Have a go at spotting everything on our nature bingo cards. Cards for spring and summer are available now, as well as cards with more abstract terms such as ‘hooked’, ‘shiny’ and ‘slow’ to challenge you to look more closely at nature when you are out and about. Get out there and start ticking them off! Who can get a full house first? You can improve your Welsh at the same time by using both English and Welsh versions together as well as the handy hints for learners.  

Spotter’s Sheets

The spotter’s sheets in Welsh and English are there to help you to recognise more of the natural world and the archaeology on your doorstep. Use our downloadable spotter’s sheets to identify animals, plants, fossils, rocks and artefacts. They can be used as an introduction to a particular theme, to remind you of helpful identification characteristics, or to learn interesting facts about ordinary things around us in Wales.

Guides…to animals and plants

Visit the nature spotters guides webpage

  • Garden Pond Snails. Are there snails in your pond, if so what are they?
  • Hitchhikers on Ocean Plastics. Some sea creatures use floating plastic, or other waste, to travel around the world. Get in touch with us if you find any in Wales.
  • Brown Seaweeds. Brown seaweeds are often the most obvious living things on a rocky shore. Learn about a few selected seaweeds to get you started on the 120 you can find in Wales!
  • Red & Green Seaweeds. When you’re next on a rocky shore, try looking for these red and green seaweeds which are common features of rock pools.

Guides…to geology

Visit the nature spotter's guide webpage.

  • Have I Found a Fossil? Use this guide if you are unsure whether the object you have found is a fossil or not.
  • The Main Fossil Groups. Working out which group your fossil belongs to will give you an idea of how old it is and tell you something about the habitat where it lived, millions of years ago.

  • Housing in Wales before 1000 BCE. Today’s houses are a recent innovation. Find out what type of houses were common just a few thousand years ago.
  • Making axes at the end of the Stone Age. People started making polished stone axes around 4000 BCE and used them to chop down trees, impress neighbours, or beat up enemies. But where do you go to find the right rocks to make an axe in Wales?

Get involved!

You can share archaeological finds with us on Twitter via @SF_Archaeology, and natural history finds via @CardiffCurator.

We currently have a project looking at new animals rafting across seas and oceans to Wales on plastics, so we really want to hear from you. Tell us if there are any other spotter’s sheets you’d like us to make. And if you complete any of our nature bingo cards, feel free to boast on social media by sharing your nature photos with us! To let us know about more sensitive things such as dinosaur footprints or rare plants, or for more help, please get in touch with our Museum Scientists.

Look out for more activities and features appearing on the ‘On Your Doorstep’ webpages through the year and keep an eye out for more archaeology which will launch fully for the 2021 Festival of Archaeology during July.

Lost worlds of Gondwana

Leonid Popov, Honorary Research Fellow, 26 May 2021

What is Gondwana?

The Museum has large fossil collections of Early Palaeozoic age (540-400 million years old) from various parts of the world. Many come from regions that in the geological past formed a huge single supercontinent, called Gondwana. Wales was also part of Gondwana, until it broke away some 480 million years ago.

Where is Gondwana located?

If we could look at the globe 400-550 million years ago, we would find a very different world. Almost all of the Northern Hemisphere was covered by an ocean called Panthalassa.

In the Southern Hemisphere, a huge landmass extended from the South Pole to the equator. There were no oceans separating South America, Africa, Australia, Antarctica and India. They were all merged in a single supercontinent, which scientists have named Gondwanaland or simply Gondwana.

It also included large parts of south and south-east Asia, and southern Europe, which were either attached to the mainland, or formed chains of islands and volcanic island arcs some distance off the Gondwanan coast. Some of these islands, such as South and North China, were the size of small continents.

When was Gondwana formed?

Gondwana was formed some time during the Ediacaran Period, by about 550-530 million years ago, as a result of the collision of several ancient continents.

First signs of complex animal life

This is the time when the first signs of complex animal life appear in the fossil record. The name of the Period comes from the Ediacara Hills in South Australia, where geologist Reg Sprigg discovered the (then) oldest known animal fossils in 1946. Ever since, Gondwana has been the most important source of our knowledge of early metazoan (complex animal) life. Important fossil localities outside Australia are known from Namibia, Newfoundland, Central Iran and Wales. All were part of Gondwana at that time.

Earth about 530 million years ago, shortly after the Gondwanan supercontinent formed
Image 1:

Earth about 530 million years ago, shortly after the Gondwanan supercontinent formed.
The oldest mineralised fossils of marine animals date from this time: (a) mineralised plate of worm from Northern Iran; (b) brachiopod from Indian Kashmir; (c) trilobite from Alai Range, Kyrgyzstan; (d) enigmatic fossil from Jordan; and (e) conodont tooth. Scale bars = 0.2 mm. Trilobite fragments about 4 mm wide.

The Cambrian Explosion

Evidence of life is scarce in rocks formed during the Ediacaran Period, but everything changed at the beginning of the Cambrian Period, just over 540 million years ago. This was the time when marine animals started to grow hard parts, or skeletons, for the first time. Remains of such animals were preserved in the rock as isolated parts, like vertebrate teeth and sponge spicules, as shells, including molluscs and brachiopods, and as complete carapaces of trilobites and similar animals. Such fossils are found in many fossil localities across Gondwana, from Newfoundland to Australia.

There are also a few locations where soft body parts of these animals are preserved. One of the richest and most important fossil localities of this kind is in Chengjiang, South China. These fossils provide convincing evidence that almost all major types of invertebrate animals that are alive today have existed since early Cambrian times. The Cambrian Explosion gets its name from the fact that most major groups of animals appeared over a (geologically) short period of time, as life diversified rapidly into a great variety of forms.

What caused the Cambrian Explosion?

There is a lot of debate among scientists and ongoing research about what caused the Cambrian Explosion, and it is likely to have resulted from the interplay of several factors rather than one single trigger. Recent research on ancient sediments gave weight to the key role played by oxygen, by showing that oxygen levels in the sea rose from the Ediacaran to Cambrian period, to near-modern levels. This would have allowed larger and more complex animals to evolve, and more complex food webs to develop. An increase in larger predators may have triggered rapid evolution of predators and prey, as natural selection adapted their bodies to better target or evade each other.

There was also a global sea level rise at this time, which greatly increased the area of shallow seas on Earth, providing more habitable space that could be filled by new species. Another possible environmental factor was an increase in calcium ions in sea water, due to volcanic activity and widespread weathering of the land. These ions would have provided the raw materials for animals to make shells, skeletons and other hard parts, making a greater variety of body plans possible.

Some scientists speculate that internal, developmental features of animals themselves may also have played a role in the Cambrian Explosion, although it is very difficult to test this idea. It is possible that animals acquired some key genes or that they crossed some threshold level of genetic complexity, making it possible to make a much bigger range of body shapes. However, the fact that some complex animals already existed in the Ediacaran period suggests that this was unlikely to have been a key trigger for the Cambrian Explosion.

About 480 million years ago, Avalonia separated from Gondwana
Image 2:

About 480 million years ago, Avalonia separated from Gondwana, and Wales started a long journey towards the tropics, meeting the east coast of Laurentia (North America) 70-80 million years later. Marine life rapidly diversified on tropical shelves, shown by these fossils from Australasian and Middle Eastern sectors of Gondwana: (a) an early coral; (b) ostracod, a minute crustacean; and (c) encrusting bryozoans on brachiopod shell.

The Ordovician diversification of life?

Life in the ancient seas went through big changes during the Ordovician Period (440-490 million years ago). Animals living on the sea bottom started to grow upwards, higher above the sea floor, and the first coral reefs started to grow about this time. This resulted in an amazing increase in the diversity of life.

In the Ordovician world, more animals lived attached to the bottom and fed by filtering plankton from sea-water. Good examples of such animals are various corals, brachiopods, bryozoans or moss animals, and crinoids or sea lilies. Living alongside these were mobile animals, including molluscs and arthropods.

Trilobites were still abundant, but gradually became less important.

Tropical seas surrounding the Australasian sector of Gondwana were an important centre for the origin of new marine life, like maritime South-East Asia is today.

 440 million years ago, the world was recovering after ice age and mass extinction.
Image 3:

440 million years ago, the world was recovering after ice age and mass extinction. Most post-extinction survivors settled in the tropics, only later migrating to higher latitudes. Early Silurian rocks from Iran preserve a rare record of that migration: (a) common brachiopods and (b) bryozoans; (c) microscopic plates from sea cucumbers; (d) rare sponges; (e) trilobite Calymene; (f) conodont teeth and (g) cone-shaped brachiopods.

The end and new beginning

Towards the end of the Ordovician Period, life on Earth faced a difficult new challenge, resulting in the second biggest mass extinction event in its history. An enormous ice cap started to grow in the Southern Hemisphere, where most of the shallow seas supporting diverse marine life were located. During the final (Hirnantian) stage of the Ordovician, a significant part of Gondwana was covered by thick ice. Evidence for this is widespread across Africa, Brazil and the Arabian Peninsula, and has most recently been found by our research team in Iran. The growing ice sheet cooled the climate and caused sea level fall, drastically changing many shallow marine habitats.

The Hirnantian was named after Cwm Hirnant near Bala, in North Wales, where this stage of geological history was first recognised. By that time, Wales was actually far away from the rapidly cooling Gondwanan world and was approaching tropical Laurentia (the ancient North American continent), as part of a small 'break-away' continent called Avalonia. Wales was also the place where the so-called "disaster Hirnantia fauna" was discovered and described for the first time. This restricted group of animals evolved in temperate latitude Gondwana following the first major pulse of global extinction. At that time, with few competitors left, they were able to spread widely across the globe.

By the end of the Ordovician Period, two-thirds of marine species were extinct and the great variety of living things found in different parts of the world had all but disappeared. Lucky survivors took over expanding shallow seas after the ice cap melted in the early Silurian Period, from around 440 million years ago. Soon marine life flourished and diversified once more. But by that time, the four major continents, Gondwana, Laurentia (North America), Baltica (Europe) and Siberia, were slowly moving northwards and towards each other, eventually joining together to form a single land-mass, Pangaea (meaning "entire Earth"), by the end of the Palaeozoic. A different world with a different history was emerging.
