Original Source: Tom Slemen, Writes, one afternoon, I gave a talk about ghosts to a group of schoolkids at a library in Liverpool. Afterwards, a school girl asked me: ‘What’s the oldest ghost ever?’ The innocent question set me thinking. Anne Boleyn’s ghost is allegedly still being seen, 469 years after her death in 1536. An apparition said to be that of Boudicca is regularly seen in Lincolnshire. I also remembered the strange account of a heating engineer named Harry Martindale, who was working in the cellar of the medieval Treasurer’s House in York in 1953, when he was startled to hear a trumpet call. Mr Martindale watched in absolute terror as a Roman soldier marched through a wall, followed by an officer on horseback with about 16 other soldiers trailing behind him. Mr Martindale cowered in a corner as he watched the eerie scene and noticed that the ghosts were marching thigh-deep in the cellar floor. He later discovered the Romans had been marching along a road which ran under the treasury. This road had long been buried, which explained why all the ghosts – with the exception of the horse-mounted officer – were visible from the thighs up.
