They were explicitly mentioned as being Celts by several classic authors. These tribes spoke the Celtiberian language and wrote it by adapting the Iberian alphabet. The numerous inscriptions that have been discovered, some of them extensive, have allowed scholars to classify the Celtiberian language as a Celtic language, one of the Hispano-Celtic languages that were spoken in pre-Roman and early Roman Iberia. Archaeologically, many elements link Celtiberians with Celts in Central Europe, but also show large differences with both the Hallstatt culture and La Tène culture.
