Yule Traditions and Symbols

Evergreens for Yule
Evergreens were cut and brought indoors to symbolize life, rebirth and renewal. They were thought to have power over death because their green never faded and they were used to defeat winter demons and hold back death and destruction. Because of their strenght and tenacity, they were also believed to encourage Sun's return.

Christmas Holly
Holly,which represents the masculine element , was often used to decorate doors, windows and fireplaces.Because of its prickliness it was thought to capture or ward off evil spirits before they could enter a home and cause harm. The holly leaves , symbolic of the Holly King, represent hope , and the red berries represent potency.

Holiday Traditions: Mistletoe
Mistletoe, which represents the female element, also holds much importance as it was used by Druid priests in special ceremonies during the Winter Solstice. They believed that its green leaves represented the fertility of the Mother Goddess, and its white berries, the seed of the Forest God or Oak King. Druids would harvest the mistletoe from sacred oak trees with golden scythes and maidens would gather underneath the trees to catch the falling branches, preventing them from falling to the ground; for if this happened, it was believed that all sacred energy in the plant would pour back into the earth. The branches and sprigs were then divided and distributed to be hung over doorways as protection against thunder, lightning and other evils. Mistletoe was also worn as an amulet for fertility, or hung above the headboard.

Yule Tree: An Important Pagan Symbol
The Yule Tree was also another important symbol in pagan tradition. Originally, it represented the Tree of Life or the World Tree among early pagans. In ancient times it was decorated with gifts people wanted to receive from the gods. It was adorned with natural ornaments such as pinecones, berries and other fruit, as well as symbols sacred to the gods and goddess. In some holiday traditions, garlands of popcorn and berries were strung around the tree so that visiting birds could feed off the tree as well.

To Honour and Protect: The Yule Log
The custom of burning the Yule Log began with the ancient Scandinavians who burned a huge log, felled from and Ash tree, to honour their god Thor. In the Celtic tradition, a continual hearth fire was kept to prevent spirits from entering the home. In order for the fire to keep burning, a large Oak tree was felled and brought into the home where the tree was placed trunk first into the hearth, with the last remnants set aside to burn with next year’s fire. It was also believed that the longer the Yule log burned, the faster the sun would come to warm the earth.

Other Yule Traditions and Symbols

Candles were another way to have an eternal flame within the home. They symbolized the light and warmth of the sun and were used to chase away evils and lure back the returning sun/son.
Wreaths were also traditional in ancient times for they symbolized the wheel of the year and the completion of another cycle. They were made of evergreens and adorned with cones and berries and hung as decoration throughout the home. They were also given as gifts to symbolize the infinity of goodwill, friendship and joyfulness.
Bells were often rung during the Winter Solstice to drive away demons that surfaced during the dark time of the year. They were rung in the morning as everyone began to wake to chase away the dark days and herald in the warmer, brighter days following the solstice.
Elves first became associated with Yule because the ancients knew that the Spirits that created the Sun inhabited the land of Elves. By including elves in the Yule celebrations, the ancients believed they were assuring the elves assistance in the coercion of the Sun to return.
Gingerbread was considered to be a specialty bread during this time since ginger had not been available until the Crusaders brought it back in the 11th century. There were strict laws regarding specialty breads in that time, so gingerbread was only allowed to be produced during the holidays and thus, it became associated with winter and Yule.
Wassail derives from the Old English words waes hael, which means “be well”, “be hale” or “good health”. It is a strong drink, usually a mixture of ale, honey and spices or mulled apple cider. When pagans went into the forest to fell the great oak for the Yule log, they would anoint the tree with wassail and bedeck them with wassail-soaked cakes, thus the ritual of wassailing was born. At home, the wassail would be poured into a large bowl during feast time and the host, when greeting his or her guests, would lift a drink and wish them “waes hael”, to which they would reply “drinc hael”, which meant “drink and be well”.
Carolling was also a popular Yule tradition when young children honoured the Winter Solstice with song. They would go through the villages, singing door to door. The villagers, in return, would reward them with tokens and sweets and small gifts which symbolized the food and prosperity given by the Mother Goddess to all her Earthly children.
