The continental Celtic languages were, at their height, spoken across most of continental Europe, from the Atlantic coast of Iberia in the west to the centre of Anatolia in the east, and from the North Sea in the north to the Alps in the south. To trace what happened to the continental Celtic languages is to follow one of the great linguistic stories of the ancient world, the story of a community of related languages that at its peak included several million speakers, that lost its continental territory to the expansion of Latin and to the migrations of Germanic and Slavic-speaking peoples, and that survived into the present only in the British Isles and (through medieval migration) in Brittany. The story is an essential part of the broader story of the Celtic language family and of the Celtic languages and oral tradition as a whole.
The Continental Celtic Languages
The continental Celtic languages include Gaulish, the most extensively documented, which was spoken across Gaul and parts of northern Italy, the Balkans, and central Europe in the Iron Age and the Roman period. Celtiberian, the Celtic language of north-central Spain, is known from a substantial corpus of bronze inscriptions dating from the second and first centuries BCE. Lepontic, the oldest attested Celtic language, is known from inscriptions of the sixth century BCE in northern Italy and Switzerland. Galatian, the Celtic language of central Anatolia, is known mainly from a small number of personal names and from a single short Greek-language text containing Galatian words. Other continental Celtic languages, including Noric and Pannonian, are known from limited evidence.
The continental Celtic languages also include a substantial body of evidence from the place names and personal names of the continental Celtic world, which preserve a rich Celtic inheritance that is still in use in the modern languages of France, Spain, Switzerland, and Austria. The Rhine, the Main, the Danube, the Rhône, the Seine, the Loire, and the Garonne are all river names of Celtic origin, and the Lyon, Paris, Luzern, Wien, and Bregenz are also of Celtic origin.
The Roman Conquest
The principal cause of the decline of the continental Celtic languages was the Roman conquest of the continental Celtic world. The conquest of Gaul, completed by Julius Caesar in the 50s BCE and consolidated by the early emperors, brought the Gaulish language into direct contact with Latin, the language of the Roman administration. The conquest of Hispania, completed in the first century BCE, brought Celtiberian and the other Celtic languages of the peninsula into similar contact. The conquest of Galatia in central Anatolia, completed in the first century BCE, brought Galatian into contact with the Greek and Latin languages of the eastern Mediterranean.
The Roman conquest was not in itself a linguistic event, but it had profound linguistic consequences. The introduction of Latin as the language of administration, of the army, of the law, and of the towns created a powerful incentive for the Celtic-speaking populations to acquire Latin, and the process of Romanisation gradually replaced the older Celtic languages with Latin in most of the former Celtic-speaking territories. By the end of the Roman period in the fifth century CE, the continental Celtic languages had been substantially reduced, and by the early medieval period they were extinct as living languages.
The Survival of Gaulish
Gaulish, the most extensively documented of the continental Celtic languages, is known from hundreds of inscriptions, a substantial body of personal names and place names, a small number of coin legends, and a few longer texts. The most famous Gaulish text is the Larzac tablet, a lead curse tablet from the second century CE found in southern France, which contains a substantial Gaulish text in the Latin alphabet and gives a vivid picture of the Gaulish language in the late Roman period. Other important Gaulish texts include the Chamalières tablet, another lead curse tablet from the first century CE, and the Lezoux tablet, a Gallo-Latin bilingual inscription from the second century CE.
Gaulish continued to be spoken in Gaul well into the Roman period, and the personal names preserved in Latin and Greek inscriptions from Gaul include a substantial number of clearly Celtic forms well into the third and fourth centuries CE, suggesting that the language was still being spoken in some parts of Gaul at this late date. By the fifth century CE, however, Gaulish had been substantially replaced by Latin as the language of the population.
The Survival of Celtiberian
Celtiberian, the Celtic language of north-central Spain, is known from a substantial corpus of bronze inscriptions dating from the second and first centuries BCE. The Celtiberian inscriptions, although often difficult to interpret, include some of the longest Celtic texts from the ancient world, and they provide important evidence for the early development of the q and p sounds that distinguish the Goidelic and Brythonic branches. The Celtiberian texts from Botorrita (the ancient Contrebia Belaisca) are particularly important, including a bronze plaque with a long Celtiberian text in the Latin alphabet. The language declined more rapidly than Gaulish, and was probably extinct by the early first century CE. The Celtiberian language left substantial traces in the place names of north-central Spain, including the famous Numancia, Segobriga, and Clunia of the Celtiberian period.
The Survival of Galatian
Galatian, the Celtic language of central Anatolia, is the most geographically remote of the continental Celtic languages. The language was brought to central Anatolia in the third century BCE by the Galatian migrants, three Celtic tribes (Trocmi, Tolistobogii, and Tectosages) who crossed the Balkans and settled in the area around modern Ankara. The Galatians maintained their Celtic identity and language for several centuries, and St Paul of Tarsus addressed his Epistle to the Galatians to a population that was still, in the first century CE, speaking a Celtic language. Galatian declined through the late Roman period, and by the early medieval period it had been completely replaced by Greek and Turkish.
The Disappearance
The continental Celtic languages disappeared as living languages through a combination of Romanisation, Germanic expansion, and Slavic expansion, the process differing across the continent. In Gaul and in the Romanised parts of the continent, Latin gradually replaced the older Celtic languages through a long process of bilingualism and language shift. In the northern and eastern parts, the Germanic and Slavic migrations of the late Roman and early medieval periods brought new languages into the former Celtic-speaking regions, and the older Celtic languages were lost in the turmoil of the migration period.
By the early medieval period, the continental Celtic languages had been substantially replaced by Latin, Germanic, and Slavic languages, and by the high medieval period they were extinct as living languages. The continental Celtic world, once extending from the Atlantic to the Bosphorus, was now reduced to the insular Celtic languages of the British Isles, and the story of the continental Celtic languages became the story of a body of evidence preserved in inscriptions, in place names, in personal names, and in loanwords in the languages that replaced them.
The Legacy
The continental Celtic languages left a substantial legacy in the languages and the cultures of modern Europe. The French language, the Spanish language, the Italian language, the Portuguese language, and the Romanian language all preserve a substantial Celtic substratum, and the place names of modern Europe, from the Rhine to the Rhône and from the Danube to the Lyon, preserve a rich Celtic inheritance. The English language, although not itself a Celtic language, has borrowed a substantial number of Celtic words and place names from the older Celtic languages of the British Isles, and the German, Slavic, and Baltic languages of the continental interior preserve traces of Celtic contact that have been the subject of recent scholarly study.
The continental Celtic legacy is one of the great cultural facts of the modern European linguistic landscape, and it is an essential part of the broader story of the Celtic civilization and of the Celtic legacy today.
