History 17:57, October 29, 2009 Snap-Apple Night by Daniel Maclise showing a Halloween party in Blarney, Ireland, in 1832. The young children on the right bob for apples. A couple in the center play a variant, which involves retrieving an apple hanging from a string. The couples at left play divination games. Halloween has origins in the ancient festival known as Samhain (pronounced sow-in or sau- an), which is derived from Old Irish and means roughly "summer's end". This was a Gaelic festival celebrated mainly in Ireland and Scotland. However, similar festivals were held by other Celts – for example the festival of Calan Gaeaf (pronounced kalan-geyf) which was held by the ancient Britons. The festival of Samhain celebrates the end of the "lighter half" of the year and beginning of the "darker half", and is sometimes[6] regarded as the "Celtic New Year". The celebration has some elements of a festival of the dead. The ancient Celts believed that the border between this world and the Otherworld became thin on Samhain, allowing spirits (both harmless and harmful) to pass through. The family's ancestors were honoured and invited home whilst harmful spirits were warded off. It is believed that the need to ward off harmful spirits led to the wearing of costumes and masks. Their purpose was to disguise oneself as a harmful spirit and thus avoid harm. In Scotland the spirits were impersonated by young men dressed in white with masked, veiled or blackened faces. Samhain was also a time to take stock of food supplies and slaughter livestock for winter stores. Bonfires played a large part in the festivities. All other fires were doused and each home lit their hearth from the bonfire. The bones of slaughtered livestock were cast into its flames. Sometimes two bonfires would be built side-by-side, and people and their livestock would walk between them as a cleansing ritual. Another common practise was divination, which often involved the use of food and drink. The name Halloween and many present-day traditions, derive from the Old English era. *Origin of name* The term Halloween, originally spelled Hallowe'en, is shortened from All Hallows' Even – e'en is a shortening of even, which is a shortening of evening. This is ultimately derived from the Old English Eallra Hālgena ǣfen.[16] It is now known as "Eve of" All Saints' Day, which is November 1st. A time of pagan festivities,[7] Popes Gregory III (731–741) and Gregory IV (827–844) tried to supplant it with the Christian holiday (All Saints' Day) by moving it from May 13 to November 1. In the 800s, the Church measured the day as starting at sunset, in accordance with the Florentine calendar. Although All Saints' Day is now considered to occur one day after Halloween, the two holidays were once celebrated on the same day. "Source: Wikipedia" .
