Mette Hardenberg

Mette Hardenberg (1569–1629), was a Danish noble and landowner. She was known as an eccentric, and became famous in contemporary Denmark when she believed herself to be possessed by a demon. She was also known for the pilgrimage as a beggar, which she undertook after a vision in a dream.

She was born to riksråd Erik Hardenberg and married noble landowner Preben Gyldenstjerne til Vosborg (d. 1616) in 1589. Mette Hardenberg became insane in 1597, after which she became a known eccentric.
