The main aim was to investigate the provenance of Viking age antler material findings of moose and red deer from Sigtuna and from three sites on the island of Gotland in the Baltic sea. This was done by analysis of the stable isotopes of carbon, nitrogen and sulphur. Thre were never any living population of these mammals on Gotland during the Viking age. δ34S-values of sulphur from this study was compared with earlier research and by studying maps of the Swedish bedrock. The δ34S-values were more like the δ34S-value for bedrock other than European granite. These bedrocks are found in the south-east of Sweden along the coast towards Gotland. The provenance of the Sigtuna antlers could be three different areas and the material from Gotnald could come from two differente regions. A student-t test between Fröjel and Sigtuna showed no significant correlation between the two populations. A comparison within the Sigtuna material showed a possible difference between two different dated phases. This could mean that an import of antlers from other areas was made when antlers in the Sigtuna region was less available.
