Résumé
This pilot study investigates the existence of seasonal movements of sheep – transhumance – in Iron Age Catalonia (North-Eastern Spain). The occurrence of seasonal movement of livestock between the coast and the interior, perhaps in relation to the Mediterranean market, was suggested for this area based on landscape and palynological studies. This hypothesis was tested on the basis of strontium, carbon and oxygen isotope analysis from seven sheep lower third molars. The evidence obtained suggests that the animals did not move across geological areas during the time of enamel mineralization. In addition, the paper provides valuable isotopic evidence that can be used in further studies.
