Samhain in the context of "Prehistoric Ireland"

Halloween, also known as All Hallows' Eve, or All Saints' Eve, is a celebration observed in many countries on 31 October, the eve of the Western Christian feast of All Hallows' Day. It is at the beginning of the observance of Allhallowtide, the time in the Christian liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed. In popular culture, Halloween has become a celebration of horror and is associated with the macabre and the supernatural.

One theory holds that many Halloween traditions were influenced by Celtic harvest festivals, particularly the Gaelic festival Samhain, which are believed to have pagan roots. Some theories go further and suggest that Samhain may have been Christianized as All Hallows' Day, along with its eve, by the Church. Other academics say Halloween began independently as a Christian holiday, being the vigil of All Hallows' Day. Celebrated in Ireland and Scotland for centuries, Irish and Scottish immigrants brought many Halloween customs to North America in the 19th century, and then through American influence various Halloween customs spread to other countries by the late 20th and early 21st century.

Imbolc or Imbolg (Irish pronunciation: [ə ˈmˠɔlˠəɡ]), also called Saint Brigid's Day (Irish: Lá Fhéile Bríde; Scottish Gaelic: Là Fhèill Brìghde; Manx: Laa'l Breeshey), is a Gaelic traditional festival on 1 February. It marks the beginning of spring, and in Christianity, it is the feast day of Saint Brigid, Ireland's patroness saint. Historically, its many folk traditions were widely observed throughout Ireland, Scotland and the Isle of Man. Imbolc falls about halfway between the winter solstice and the spring equinox and is one of the four Gaelic seasonal festivals, along with Bealtaine, Lughnasadh and Samhain.

Imbolc is mentioned in early Irish literature, although less often than the other seasonal festivals. Historians suggest that Imbolc was originally a pre-Christian (or pagan) festival associated with the lambing season, the coming of spring, and possibly the goddess Brigid, proposing that the saint and her feast day might be Christianizations. A feast of Saint Brigid was first mentioned in the Middle Ages, but its customs were not recorded in detail until the early modern era. In recent centuries, Brigid's crosses have been woven on St Brigid's Day and hung over doors and windows to protect against fire, illness, and evil. People also made a doll of Brigid (a Brídeóg), which was paraded around the community by girls, sometimes accompanied by 'strawboys'. Brigid was said to visit one's home on St Brigid's Eve. To receive her blessings, people would make a bed for Brigid, leave her food and drink, and set items of clothing outside for her to bless. Holy wells would be visited, a special meal would be had, and the day was traditionally linked with weather lore.
