Crossing the Veil: The Pre-Christian Origins of Halloween and Samhain

Crossing the Veil: The Pre-Christian Origins of Halloween and Samhain


Halloween, or the ancient Samhain, is considered the time of year when the veil between our world and the spirit world is at its thinnest. As darkness falls and families light their pumpkin Jack-o'-lanterns, they are, perhaps unknowingly, repeating the ancient traditions of honoring the dead and marking the beginning of the ‘dark half’ of the year.

Halloween Origins: Celtic Harvest Festivals

Halloween is an annual celebration held largely in the western world on October 31st. Starting in the evening, children, and sometimes adults, dress in masks and costumes, traditionally as ghostly figures, witches, or the undead – vampires, zombies, skeletons. They go knocking door-to-door, requesting treats, or else threatening a mischievous trick upon the household. Typical activities of the modern observance can include costume parties, pumpkin carving, trick-or-treating, lighting bonfires, playing pranks, and more.

Hallowe’en, a shortened form of "All Hallows' Evening" is an echo of Celtic harvest festivals of pre-Christian Europe. Observed now in several countries around the world, it is the evening before ‘All Hallows Day’, when saints (hallows) and martyrs are remembered by people of many Christian denominations. This ritual, however, coincides with (and some scholars suggest co-opted) the ancient observance of Samhain.



What were Pagan Rituals on Samhain?

Samhain (pronounced sah-van or sow-in) is the traditional Gaelic festival marking the change of seasons and the approach of winter. There are many important events that begin or happen around the time of Samhain in Irish myth . For example, people would bring their cattle back from the summer pastures and slaughter livestock in preparation for the upcoming winter. They would also light ritual bonfires for protection and cleansing as they wished to mimic the sun and hold back the darkness. It was also a time when people believed that spirits or fairies (the Aos Sí ) were more likely to pass into our world.

Dead and departed relatives played a central role in the tradition, as the connection between the living and dead was believed to be stronger at Samhain, and there was a chance to communicate. Souls of the deceased were thought to return to their homes. Feasts were held and places were set at tables as a way to welcome them home. Food and drink was offered to the unpredictable spirits and fairies to ensure continued health and good fortune.

Transforming Samhain

The idea that souls return home on a certain day of the year is repeated across many cultures around the world. Día de Muertos , or the Day of the Dead, is a similar holiday held around the same time of year in Mexico celebrating and honoring family members who have died.

Samhain saw a metamorphosis due to the early Church. In The History of Halloween or Samhain , Jack Santino writes:

“As a result of their efforts to wipe out ‘pagan’ holidays, such as Samhain, the Christians succeeded in effecting major transformations in it. In 601 A.D. Pope Gregory the First issued a now famous edict to his missionaries concerning the native beliefs and customs of the peoples he hoped to convert. Rather than try to obliterate native peoples' customs and beliefs, the pope instructed his missionaries to use them: if a group of people worshipped a tree, rather than cut it down, he advised them to consecrate it to Christ and allow its continued worship.”

In the 12th century, obligatory holy days across Europe involved town criers dressed all in black, ringing mournful bells and calling on Christians to remember the poor souls of the dead. Special ‘soul cakes’ would be baked and shared. This custom of “souling” was present in England, Germany, Belgium, Austria, and Italy, and this is thought to be the precursor of trick-or-treating.

Eventually, mumming and guising (going door-to-door in disguise and performing in exchange for food) was taken up as another variation on these ancient customs. Pranks were thought to be a way of confounding evil spirits. Pranks at Samhain date as far back as 1736 in Scotland and Ireland, and this led to Samhain being dubbed “ Mischief Night ”.

Controversy Surrounding Modern Halloween Practices

Many of the modern practices for Halloween date to 19th century England and North America. Fortune telling and divination have traditionally played a part in celebrations. Games were played with the intention to divine one’s future. Nuts and fruit featured in eating and drinking games, and soul cakes were prepared.

Around Halloween, pumpkins are hollowed out, and spooky faces are carved into them, creating Jack-o'-lanterns. Candles are then lit inside the pumpkins, creating eerie lanterns, and serving as signals that a household observes Halloween. Pumpkins are frequently used today as they’re easier to carve and a symbol of harvest, but the original lanterns in Ireland and Scotland were carved from turnips. These turnip lanterns were used to frighten off evil spirits by guisers, and were a motif of the Irish Christian folk tale of Jack, a wandering soul who was denied entry into both heaven and hell.

Observing Halloween is not without controversy. Some religions discourage participation, suggesting that it trivializes Samhain, it has satanic associations, or it is an inappropriate tribute to paganism or the occult. However, the modern practices heavily influenced by commercialization and popular culture differ appreciably from the ancient traditions of Samhain and All Hallows’ Eve.

Still, the connection exists and the history is clear - when you light a Jack-o'-lantern and brighten the darkening season, you’re carrying on an age-old tradition that bridges cultures around the world and reaffirms our connection to our departed loved ones.
