Lighting Candles and Bonfires
For much of the early history of Halloween, towering bonfires were used to light the way for souls seeking the afterlife. These days, lighting candles have generally replaced the large traditional blazes.
Seeing Ghosts
The festival of Samhain marked the transition to the new year at the end of the harvest and beginning of the winter. Celtic people believed that during the festival, spirits walked the Earth. Later on, Christian missionaries introduced All Souls’ Day on November 2, which perpetuated the idea of the living coming into contact with the dead around the same time of year.
Trick-or-Treating
There is much debate around the origins of trick-or-treating, but generally there are three theories. The first theory suggests that during Samhain, Celtic people would leave food out to appease the spirits traveling the Earth at night. Over time, people began to dress as these unearthly beings in exchange for similar offerings of food and drink.
The second theory speculates that the candy boon stems from the Scottish practice of guising, which is a secular version of “souling.” During the Middle Ages, generally children and poor adults would collect food and money from local homes in return for prayers for the dead on All Souls’ Day. Guisers dropped the prayers in favor of non-religious practices with the inclusion of songs, jokes, and other “tricks.”
A third theory argues that modern American trick-or-treating stems from “belsnickeling,” a German-American Christmas tradition where children would dress in costume and then call on their neighbors to see if the adults could guess the identities of the disguised. In one version of the practice, the children were rewarded with food or other treats if no one could identify them.
