The collection belonging to the Swedish History Museum contain a great multitude of various objects. Most of them are archaeological finds but there is also a large subdivision containing ecclesiastical artefacts, in this case a helmet from a heraldic achievement carried in a funeral procession. The achievement hung in St. Mary’s church in Sigtuna but the helmet came loose at some point. Eventually, in 1888, the congregation sold the helmet along other unused objects to the History Museum. The crest show a pair of ox horn denoting the family name Oxenstierna, one of the most distinguished families in Swedish society since 1292. The achievement was most likely made for Bengt Oxenstierna (+1495) or his son Christiern (+1520).
