Single Viking age silver finds in Ireland also appear which raises the question of what the purpose of burying silver hoards was. The threat of Viking raids would be sufficient for the burial of hoards in order to protect the wealth which could be later, but was not, reclaimed. This is a plausible explanation however there are other possible reasons why hoards were buried and then not recovered. One theory is that pagans in the Viking Age believed that the deceased would need riches in the afterlife which were the treasures he had buried whilst still alive. However this story was written long after the Christianisation of Scandinavia and so it in uncertain about its accuracy. Another possible reason for burying hoards was in order to protect silver generally (without specific threat of invasion) by leaders so that they could in time reward their followers with silver. This display of wealth and power could also have lead to hoards of silver being buried in order to eliminate them from circulation, creating a talking point for others.
