What “Celtic art” means
The phrase covers a long, uneven run of decorated objects, not the output of one nation. Greek and Roman writers used “Celts” for various peoples north of the Mediterranean, and in modern times “Celtic” became the name of a language family. Art historians then borrowed it for a distinctive curving style that appears on metalwork from about the fifth century BCE. That style is named La Tène style, after a site on Lake Neuchâtel in Switzerland where many decorated weapons and tools were recovered from the 1850s onward.
The people who made these objects are called Celtic by convention, and some scholars prefer more cautious wording. They also left no written explanations of their art. Everything below is therefore read from the objects themselves, from where they were found, and from comparison with neighbouring cultures.
Before La Tène: the Hallstatt background
The earlier Hallstatt culture of central Europe, running from roughly 800 to 450 BCE, favoured geometric decoration: bands, triangles and concentric circles on pottery, bronze vessels and belt plates. It takes its name from a cemetery above the salt workings of Austria, and Hallstatt salt mining was one source of the wealth that bought imported goods. Rich burials show the result. A grave at Vix in Burgundy, from about 500 BCE, held a huge Greek bronze mixing bowl and a gold neck ring, evidence of long-distance contact with the Mediterranean.
The birth of the La Tène style
Around the middle of the fifth century BCE, craftworkers in the western part of central Europe began to rework imported motifs. Palmettes and lotus buds, familiar from Greek objects and from the Etruscan civilization of northern Italy, were bent into S-curves, tendrils, commas and lyre-shaped loops. Many designs seem to rest on compass-drawn geometry, and they often hide faces or animal heads within the curves.
Scholars have given names to several phases. An early vegetal phase gives way to the Waldalgesheim style, named after a rich burial in Germany from the later fourth century BCE. Later work includes a so-called Plastic style, with swelling relief forms, and a Sword style on scabbards in the Danube region. These labels are modern conveniences, and regional workshops did not follow a single path.
What survives, and why it is mostly metal
Most surviving Celtic art is metal because metal was buried or thrown into water as an offering and lasted. Typical finds include:
- gold and bronze neck rings and brooches, the subject of the long-running study of Celtic torcs and brooches
- helmets, shields and decorated scabbards
- bronze mirrors engraved with curving patterns
- buckets, flagons and horse gear
- coins that began as copies of Greek types and slowly turned abstract
The Battersea shield, dredged from the Thames, is sheet bronze set with red glass or enamel and is usually dated to the last few centuries BCE. The craft behind such objects is explored through Celtic metalworking techniques such as casting, hammering and enamelling. Wood, leather and textiles, which probably carried a great deal of decoration, have mostly rotted away, so the record is skewed toward status goods that elites chose to bury.
Some stone survives too. A life-size sandstone warrior from Glauberg in Germany, found in the 1990s and dated to around 500 BCE, wears a leaf-shaped crown, and carved heads from Bohemia and southern France show that the style reached monumental scale.
Trade, status and meaning
Fine objects moved along trade routes that also carried amber, salt, wine and metals. The amber trade routes linking the Baltic to the Mediterranean ran through the same regions where the early style developed. Gold and imported wine vessels in graves suggest that art was tied to rank, feasting and display.
Whether the patterns also carried meaning is harder to say. Spirals, wheels, birds, boars and human heads recur, and it is tempting to read them as a symbolic language. The honest position is that Celtic symbolic motifs can be described but their meanings are inferred, partly from later writers and partly from the contexts in which objects were found.
The Roman period and the north-west
The Roman conquest of Gaul, between 58 and 50 BCE, ended the independent production of the style on the continent, where it blended into Gallo-Roman fashions. In Britain, conquest began with the invasion of 43 CE and covered the south first. In Ireland, which Rome never conquered, and in parts of northern Britain, curvilinear decoration kept developing.
In Scotland, the Pictish symbol stones, carved from roughly the sixth or seventh century CE, show animals and abstract signs in a curving manner that some scholars link to earlier Iron Age traditions. The symbols themselves are a separate system whose meaning is still debated.
Insular art: monasteries and Christian patrons
From the seventh century, Irish and British monasteries and Anglo-Saxon workshops produced what is called Insular art. It fuses old spirals with animal ornament of Germanic origin and with interlace, a plaited pattern that came from the wider Roman and post-Roman world. Brooches such as the Tara Brooch and liturgical vessels such as the Ardagh Chalice, both generally dated to the eighth century, show the metalwork at its finest.
The same designs fill gospel books. These are early medieval Christian works, not Iron Age ones, and the best known is the Book of Kells. The interlace that dominates their pages and stone crosses is covered by studies of Celtic knotwork patterns, which also separate documented history from modern claims.
Revivals and what is really old
The Tara Brooch was found in 1850 and was shown at the Great Exhibition of 1851 in London. It sparked a fashion for jewellery, architecture and book design in an imagined “Celtic” style. Arts and Crafts and Art Nouveau designers took up spirals and knots, and the same imagery fills modern logos, tattoos and tourist goods.
Much of what is sold as ancient Celtic design is therefore a nineteenth- and twentieth-century reworking. The knotted borders and ring-headed crosses people associate with the word “Celtic” are mostly early medieval Christian, not Iron Age.
Seeing it for yourself
Many of the main pieces can be seen in museums, among them the British Museum, the National Museum of Ireland in Dublin, the National Museums Scotland and several museums in Germany, France and the Czech Republic. The Book of Kells is kept at Trinity College Dublin. Objects in museums are often displayed in cases that cut them off from their burial or watery contexts, so reading the labels for find-spot and date helps a great deal in understanding what each piece may have meant to its owner.
