Viking axe from Mammen.
In 1868 a farmer began to dig into the mound Bjerringhøj at Mammen near Viborg. During this work he chanced upon an unusually richly-furnished grave, which has become known as the grave from Mammen. A magnate was buried in the grave during the winter of 970-71 AD. He was given an expensive costume, a ceremonial axe with inlaid silver decoration and a large wax candle.
On one side a tree motif can be seen. It may symbolise the Christian Tree of Life or the pagan tree Yggdrasil. On the other side is an animal figure – perhaps the rooster Gullinkambi (Old Norse “golden comb”) or the Phoenix. According to Norse mythology Gullinkambi sits on top of the tree Yggdrasil. Here it wakes the Viking warriors every morning and it will crow at the beginning of Ragnarok (the end of the world).
