Mystery: Mistletoe Kiss

A beautiful kiss under a mistletoe is a tradition practised by many during Christmas; but what is the mystery behind this? Mistletoe is the common name for most obligate hemiparasitic plants in the order Santalales. These plants attach to and penetrate the branches of a tree or shrub by a structure called the haustorium, through which they absorb water and nutrients from the host plant.

The common explanation says that early Christians integrated mistletoe into their celebrations as the religion spread across third-century Europe. The rationale predates the early Christians and goes back to the Norse god Baldur — second son of Odin, god of truth and light — who was so beloved by the other gods that they sought to protect him from all the dangers of the world.

His mother, the goddess Frigg, "took an oath from fire and water, iron and all metals, stones and earth, from trees, sicknesses and poisons, and from all four-footed beasts, birds and creeping things, that they would not hurt Baldur." And thus the beautiful god was deemed invincible.

At a large gathering soon after, stones, arrows, and flame were all flung at Baldur to test his might. Nothing worked, and he walked away unscathed. Jealous of Baldur's new powers, the mischievous Loki set out to find the one thing on Earth that might be able to hurt him. He found that the goddess Frigg forgot to ask mistletoe — tiny and forgotten — not to harm her beloved son. In the end, a dart fashioned from the little plant was used to murder Baldur in front of all the other gods who loved him so dearly.
Frigg, of course, was devastated. Steve Whysall at the Vancouver Sun explains that the tears of Baldur's mother became the berries of the plant, and it was decreed that "mistletoe would never again be used as a weapon and that she would place a kiss on anyone who passed under it."

And thus we hang mistletoe underneath our doorways come the holidays — so that we never overlook it again.
