The authors have sampled and analysed pigments from murals in seven Medieval churches in the northern 2/3 of Sweden. These churches are, listed from south to north: Trönö, Enånger, Hälsingtuna, Alnö, Liden, Grundsunda and Nederluleå.The murals date from c. 1300–1550.The analyses were performed with a Hitachi S-4300 scanning electron microscope. The churches of Enånger and Alnö are richly decorated, and they also yielded the most interesting results. In Enånger we identified ultramarine and yellow volborthite, a rare copper vanadate mineral. In Hälsingtuna the infrequently used mineral vivianite was found. Some of these churches were presumably important sojourns for pilgrims en route along the coast of the Baltic Sea to Nidaros-Trondheim. The murals in the Old church of Nederluleå, 800 km north of Stockholm, are generally attributed to the workshop of the renowned master Albertus Pictor, and our pigment analyses support this. In Trönö, Liden and Grundsunda only fragmentary murals survive. Seven lead pigments were selected from four churches and analyzed with a mass spectrometer to determine their lead isotope ratios. The lead pigments in Hälsingtuna, Grundsunda and Nederluleå originate in Germany, presumably the Harz or Erzgebirge regions. Three lead pigments used at Enånger were found to be a mixture of pigments from Germany and Sweden, in the latter case from the Bergslagen region, where mines were worked quite early. This is the first time that we have identified a Medieval lead pigment with a Swedish origin.
