In 1905 a part of the mound Hogebeintum, Friesland, was excavated. They found an hollowed out oak tree with the skeleton of a woman inside, a so-called tree-trunk-coffin. Because trees are very sparse in this area, one assumes that this oak must have been imported from far away.
The woman was buried with a beautiful necklace which was made of glass, amber, mother-of-pearl and bone beads. Because of these two things, the oaktree and the necklace, the notion that she was a lady of high status is very likely. She was 40-50 years old when she died, an old age for that time period.
The Frisian public gave her the name Beitske. A name that is truly Frisian and also refers to the mound Hogebeintum.
