The history of Halloween becomes a bit more interesting when it is known that the Druids used this day to sacrifice victims to their deities. This sacrifice was conducted by burning their victims in cages made from wicker. Before this ceremony began, all fires were extinguished. They were all lit again from the sacrificial fire following the end of the ceremony. October 31st was the day when summer officially ended for 5th century BC Ireland. It was believed by the Celts that ghosts walked among the living on this day. They called this holiday Samhain. It was the time of the third and last harvest of the year. It was also the Celtic New Year. The Celts observed this day as their New Year most likely because the sun is at its lowest point on the horizon. This was measured by Britain and Ireland’s ancient standing stones.
