Celtic Protection Symbol
There are several Celtic protection symbols, including the shield knot, Triquetra, Pictish knot, Celtic cross, shamrock, mistletoe, suli, sheiah dog, and raven.
Consider first the various knots and crosses that are Celtic protection symbols. Celtic knots are often intricate and complex. In protection knots, the more complex their knot work, the more powerful the protection. They were formed to protect against demons, evil spirits, and wicked plots.
The shield knot offers protection against evil forces and will also call upon the gods from the four corners of the world. Any knot that has four corners is considered to be a shield knot. The four corners have multiple meanings: the four gods, seasons, or the elements of the earth - earth, wind, water, and air.
The Triquetra was used for protection as far back as the Wicca religion. It stands for the three aspects of the triple goddess: maiden, mother, and crone. It is also called a trefoil knot and is a very simple knot to make by using an overhand knot and connecting the two ends.
Pictish knots relied upon geometry and abstraction to make the patterns, sometimes with a set of triangles interwoven. It was used to protect against any magical rites that went wrong and missed their mark.
The basic Celtic cross pattern has been used for centuries. It is a crucifix within a circle and is believed to protect against all kinds of spiritual dangers. Sometimes the circle is found close to the center of the cross and other times it is almost at the end of the shorter arms of the cross. You will find these crosses with Celtic symbols engraved on them or with inlaid jewels. Spirals and knots show the complexity of nature and eternity that has no beginning and no end.
No one is sure about the origin of these crosses. Some say the circle is a halo and others say it represents eternal life. Others believe the circle dates back to the ancient times and symbolizes the Druid sun god and was stolen by the Christians. Some historians say the circle comes from an old practice of hanging a wreath on a cross to show victory. Then there's the legend of St. Patrick. Supposedly, he saw a Pagan statue with a circle (for the sun god) and he made the sign of the cross and blessed it. He obviously wanted to bring the Druid religion into Christianity as he ordained many Druid priests.
Here are a few more Celtic Protection symbols that represent gods, goddesses, animals, or plants.
Shamrock -- The trefoil, or the cloverleaf, is native to Ireland. It can be representative of the earth, sea, and sky or the three stages of man. It is used as a protective charm against evil and was used by St. Patrick to symbolize the Holy Trinity.
Mistletoe -- The power of mistletoe comes from the ancient belief that it was the sacred plant of the sun. This is because it lives in trees, which are also sacred, and has no roots. It has been used for protection and healing throughout time, especially in Winter Solstice rituals. It was also hung in houses to retain the love in the household and was replaced at certain times, a tradition that led to kissing under it.
Suli -- This is an amulet that protects against spiritual weakness. It shows the sun goddess inside a circle of flames.
The Sheiah Dog -- This ancient symbol has a dog inside a circle. He protected and guarded the secrets of the Druids and offered protection from black magic.
The Raven -- This symbol is not only a Celtic symbol but is used by North American Indians as well. It is believed to protect against black magic.
