Samhain: When the Boundary to the Otherworld Grows Thin

Festivals & Customs Samhain: When the Boundary to the Otherworld Grows Thin

Samhain (Irish, pronounced roughly "sow-in") marked among the Celts the beginning of the winter half of the year – early November. It was the most important of the four great Celtic festivals and counted as the turn of the year: the end of harvest time and the beginning of the dark half of the year.

The festival at the edge of the year

"Wits must he have who wanders wide, but all is easy at home."Hávamál 5, after Henry A. Bellows 1923 (public domain)

Samhain (1 November) was the most important festival of the Celtic year – the transition from the bright to the dark half of the year, the end of harvest and the beginning of winter. For the Celts the new year began here, so to speak.

When the otherworld is near

On the night of Samhain the boundary to the otherworld was regarded as especially permeable. Spirits, ancestors and beings from the world beyond could come across. People lit fires, made offerings and protected themselves from uncanny visitors.

From Samhain to Halloween

Through the Christian reinterpretation as All Saints' (1 November) and All Souls', Samhain lives on to this day – above all in Irish-influenced Halloween. Today's pumpkin has its root in the hollowed-out turnips of the old customs.

A festival, not a god

Samhain stands at the beginning of the dark half of the year, as Beltane at the beginning of the bright. Both festivals frame the Celtic year and show a people that lived in the rhythm of light and dark.

Evidence: Samhain is well attested in medieval Irish texts (Sanas Cormaic, Tochmarc Emire, Serglige Con Culainn).
Myth check: There was no "god Samhain" – that is an invention of the 18th/19th century. Samhain is the name of the festival (and the month), not of a deity. And the festival is Celtic, not Germanic.
What is documented: Samhain as the beginning of the winter half of the year and the most important Celtic festival (medieval Irish sources; Sanas Cormaic). The link with remembrance of the dead. The overlay by All Saints/All Souls and the development from All Hallows' Eve to Halloween.
What is myth/interpretation: Much about the exact Samhain rituals comes from medieval Irish texts, long after the pagan era. The popular "Celtic god of the dead Samhain" is an invention of the 18th/19th centuries – Samhain is a festival, not a god. Pumpkin, trick-or-treat and costumes are modern, above all American, developments.

Samhain is the dark threshold of the Celtic year – a festival of the ancestors that echoes into our Halloween. Related is the Germanic idea of the Rough Nights. More in the overview Celtic Religion.
