This is the baptismal font in þingvallakirkja, the church at þingvellir which is the place where the parliament was held in Iceland around the year 1000. The picture was taken on Good Friday 2004.
I was struck by this picture, which I found quite by accident, because it so neatly captures the moment when the Vikings embraced Christianity and acquired literacy — the moment when their most enduring monuments, the sagas, were recorded.
