Whether we choose to believe or not in ghosts and spirits, there is no denying that we only have to look through history to find a wide range of spooky encounters.
In the 1st century AD, a ghost was reported to haunt a house in Athens belonging to Pliny the Younger. According to Pliny the ghost would rattle chains and take the form of an old man with a beard.
The first poltergeist was recorded in 856AD at a farmhouse on the banks of the River Rhine in Germany. The spirit tormented the family by throwing stones, banging on walls and making fires. Even when several priests armed with holy relics came to visit, it sent them packing with a hale of stones.
Sightings of spectral armies after key English Civil War battles were reported in contemporary sources, similar accounts also came from Gettysburg, The Somme and Gallipoli.
The last two hundred years has seen a huge increase of interest in science but also in the spirit world. It seems that no matter how much we progress, we have a natural interest in ghosts.
