THE ancient Celts were various population groups living in several parts of Europe north of the Mediterranean region from the Late Bronze Age onwards. Given the name Celt by ancient writers, these tribes often migrated and so eventually occupied territories from Portugal to Turkey.
Although diverse tribes the ancient Celts spoke the same language and maintained the same artistic tradition which is characterised by the use of idiosyncratic flowing lines and forms. Celtic languages are still spoken today in parts of the British Isles and northern France.
Ancient writers gave the name Celts to various population groups living across central Europe inland from the Mediterranean coastal areas. Most scholars agree that the Celtic culture first appeared in the Late Bronze Age in the area of the upper Danube sometime around the 13th century BCE.
