BISKOPS ARNÖ, SWEDEN—The Local reports that a small fragment of a medieval stamp was recovered on an island in central Sweden during archaeological investigations ahead of the construction of a new pipeline. Archaeologist Maria Lingström found the object with a metal detector in a three-foot-wide trench. It is thought to have belonged to Christian archbishop Petrus Philippi, who died in A.D. 1341. “Only about 50 seal stamps that belonged to the clergy have been found so far in Sweden,” Lingström said. “This particular stamp was personal and the archbishop carried it with him at all times.” His signature seal stamp was likely destroyed upon the bishop’s death.
