There seems to quite a few haunted tales concerning spirits or ghosts attached to certain items. There is the famous Spedlins Bible which became forever interlinked with the ghost when used to exorcise it. Other tales concern bodily parts such as skulls. Do you know any such accounts and whether there is any factual basis for them? Below is the tale of Calgarth Hall:
According to legend, the owners, a Mr and Mrs Kraster Cook were framed one Christmas by Myles Phillipson, a magistrate. He planted a silver cup upon their persons when they came around to visit him. The crime was punishable by death and Phillipson gained control of Calgarth hall, but not before being cursed by Mrs Dorothy Cook. After the death of Mr and Mrs Cook, two skulls appeared at Calgarth Hall and they were first noticed at Christmas on the first anniversary of the alleged silver cup theft. Phillipson's prosperity dwindled and each time they tried to remove or destroy the skulls they reappeared again. Eventually Calgarth Hall was occupied by Dr Watson, the Bishop of Llandaff. he performed an exorcism which apparently calmed the spirits. The skulls were bricked up behind a wall in the Hall.
Head collecting was important to the celts and I can see why it would be believed that spirits are connected to their lost heads.
