English: MNS/A/20192 Glazed Easter eggs were produced in the 11th-13th centuries. In Poland, they are known from excavations on settlements and burial mounds and, much more frequently, from archaeological work on early medieval cemeteries, from richly furnished skeleton graves, including children's ones. They are considered unique objects of high material value, but it has not been possible to explain their function so far. Rattle Easter eggs from children's graves are sometimes regarded as toys, while those discovered in burials of adult women and men are associated with the sphere of beliefs and rituals. Their presence may be explained by the widespread and ancient belief in the rebirth of life, symbolised by the egg.
