Christmas Traditions
Mistletoe
Kissing someone who happens to being stood under a sprig of mistletoe is seen as a tradition popularised in Victorian England. However even this relatively modern tradition has much more ancient echoes in that Mistletoe bears its fruit around the time of the Winter Solstice, and it's supposed mythical ability to heal and increase fertility.
Another hint of its integration from pagan ceremonies into Christmas tradition is said that the mistletoe plant used to be a tree, and its wood was used to make the Cross on which Jesus was crucified. After the Crucifixion, the plant shriveled to became the parasitic vine we know today.
