The one-line summary

A Wiccan and Neo-Pagan celebration of the autumnal equinox, observed around September 22-23 in the Northern Hemisphere, marking the point in the year when day and night are of equal length. The festival is named after the Welsh mythological figure Mabon ap Modron, and is associated with the second harvest, the descent into darkness, and the balance of light and shadow. One of the eight Wiccan Sabbats.

Origin

The name "Mabon" was coined by the American Wiccan author Aidan Kelly in the 1970s, as part of his reorganization of the Wiccan ritual calendar. Kelly chose the name to refer to the autumnal equinox, because the Welsh mythological figure Mabon ap Modron (a divine child who is stolen from his mother and held captive in the underworld) parallels the agricultural story of the sun being held captive by the dark season. The name was widely adopted by the Wiccan community, and is now the most common name for the autumnal equinox festival in Wicca and Neo-Paganism.

The festival itself is older than the name, and has been observed in various forms throughout history. The agricultural significance of the autumnal equinox has been recognized since the earliest agricultural societies, and the festival has been widely observed in many cultures, including the Celtic, Germanic, and Roman traditions. The Roman festival of the autumnal equinox was associated with the goddess Pomona (the goddess of fruit trees), and the Anglo-Saxon festival of Hรฆrfest (the harvest) was associated with the gathering of the harvest and the preparation for winter.

The astronomical autumnal equinox is the basis for several public holidays, including the Japanese Autumnal Equinox Day (็ง‹ๅˆ†ใฎๆ—ฅ, Shubun no Hi, September 22-23), which is a public holiday in Japan and is part of the longer Silver Week (ใ‚ทใƒซใƒใƒผ ใ‚ฆใ‚ฃใƒผใ‚ฏ). The festival is also associated with the Mid-Autumn Festival in many East Asian cultures, and with the Mexican Dรญa de la Independencia (September 16, the day closest to the equinox).

Mabon ap Modron

Mabon ap Modron is a figure from Welsh mythology, mentioned in the medieval Welsh tales "Culhwch and Olwen" and "The Dream of Macsen Wledig". According to the story, Mabon was the son of Modron (a divine mother figure associated with the Celtic underworld), and was kidnapped from his mother three days after his birth. He was held captive in the underworld (Caer Loyw or Gloucester) until he was freed by King Arthur's men, who needed his help in the hunt for the boar Twrch Trwyth.

The story of Mabon ap Modron is one of the most famous in Welsh mythology, and parallels the Greek myth of Persephone (a divine child who is stolen from her mother and held captive in the underworld for part of the year). The myth has been interpreted as a metaphor for the agricultural cycle, with the stolen child representing the sun or the harvest, and the underworld representing the dark season of the year. The myth is also interpreted as a metaphor for the human condition, with the stolen child representing the divine spark within each person that must be recovered through spiritual practice.

The name "Mabon" is derived from the Common Celtic *Makkwo- (meaning "youth" or "son") and is related to the name of the Irish hero Mac ร“g (the Young Son), who is also associated with the Celtic underworld. The figure of the divine child who is stolen from his mother is one of the most common themes in Celtic mythology, and is widely interpreted as a metaphor for the agricultural cycle and the human relationship with the divine.

How it is observed

Mabon is observed with several distinctive traditions, each with its own history and meaning. The most prominent are: (1) the giving of thanks for the harvest, particularly the autumn fruits and vegetables; (2) the decoration of the home with autumn leaves, gourds, and pine cones; (3) the honouring of the balance of light and shadow, with rituals that emphasize the equal length of day and night; (4) the preparation for the coming winter, including the stocking of pantries and the making of preserves; and (5) the honouring of the god Mabon and the descent into the darker half of the year.

The giving of thanks for the harvest is one of the most distinctive customs of Mabon. The harvest is the central theme of the festival, and many Wiccan communities hold harvest feasts with traditional foods such as apples, pumpkins, squash, and root vegetables. The feast is typically shared with family and friends, and is often associated with the giving of thanks for the abundance of the year. The custom of the harvest feast is the basis for the American Thanksgiving holiday, which is observed on the fourth Thursday of November and which has similar themes of harvest and gratitude.

The decoration of the home with autumn leaves, gourds, and pine cones is another distinctive Mabon custom. The decorations are often made with foraged materials, and the act of gathering the materials is considered an important part of the festival. The custom is the basis for the American Thanksgiving decorations of cornucopias, pumpkins, and autumn leaves, and is also the basis for the Halloween decorations of pumpkins and gourds.

Mabon is one of the eight Wiccan Sabbats, and is part of a larger cycle of Pagan observances that includes the four Gaelic seasonal festivals of Imbolc, Beltane, Lughnasadh, and Samhain, and the four solar festivals of Ostara, Litha, Mabon, and Yule. The festival is also related to the Christian feast of Michaelmas (September 29), the Jewish festival of Sukkot, and the American Thanksgiving holiday. The festival is widely observed in Wiccan and Neo-Pagan communities worldwide.
