Samhain

Samhain (pronounced /ˈsɑːwɪn/ SAH-win or /ˈsaʊ.ɪn/ SOW-in Irish pronunciation: [sˠaunʲ]) is a Gaelic festival marking the end of the harvest season and the beginning of winter or the "darker half" of the year. It is celebrated from sunset on 31 October to sunset on 1 November, or about halfway between the autumn equinox and the winter solstice. It is one of the four Gaelic seasonal festivals, along with Imbolc, Beltane and Lughnasadh. Historically, it was widely observed throughout Ireland, and later the Isle of Man and Scotland. Kindred festivals were held at the same time of year in other Celtic lands; for example the Brythonic Calan Gaeaf (in Wales), Kalan Gwav (in Cornwall), and Kalan Goañv (in Brittany).

Samhain is mentioned in some of the earliest Irish literature and is known to have pre-Christian roots. Many important events in Irish mythology happen or begin on Samhain. It was the time when cattle were brought back down from the summer pastures and when livestock were slaughtered for the winter. As at Beltane, special bonfires were lit. These were deemed to have protective and cleansing powers and there were rituals involving them. Samhain (like Beltane) was seen as a liminal time, when the spirits or fairies (the Aos Sí) could more easily come into our world. Most scholars see the Aos Sí as remnants of the pagan gods and nature spirits. It was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter. Offerings of food and drink were left for them. The souls of the dead were also thought to revisit their homes. Feasts were had, at which the souls of dead kin were beckoned to attend and a place set at the table for them. Mumming and guising were part of the festival, and involved people going door-to-door in costume (or in disguise), often reciting verses in exchange for food. The costumes may have been a way of imitating, or disguising oneself from, the Aos Sí. Divination rituals were also a big part of the festival and often involved nuts and apples. In the late 19th century, Sir John Rhys and Sir James Frazer suggested that it was the "Celtic New Year", and this view has been repeated by some other scholars.

In the 9th century, the Roman Catholic Church shifted the date of All Saints' Day to 1 November, while 2 November later became All Souls' Day. Over time, Samhain and All Saints'/All Souls' merged to create the modern Halloween.[4] Historians have used the name 'Samhain' to refer to Gaelic 'Halloween' customs up until the 19th century.

Since the latter 20th century, Celtic neopagans and Wiccans have observed Samhain, or something based on it, as a religious holiday. Neopagans in the Southern Hemisphere often celebrate Samhain at the other end of the year (~30 April – 1 May).
