Honoring the Tree Spirits


Many believe the practice of knocking on wood or touching wood goes far back to pre-Christian times.

During Pagan times people firmly believed in tree spirits. Trees were worshiped.  

The concept that trees had magical powers was commonly acknowledged.

The dryads of the trees could heal the sick and give blessings of good fortune.

Treated badly the dryads could also put an end to your happiness.

The notion that nymphs, spirits, gods and goddesses reside in trees had a deep impact on humans.

Trees were thereby treated with respect and honored.  You always wanted to be on good terms with the dryads.

Some would also go to a sacred tree and whisper their hopes, dreams and secrets to the tree. Before doing so, they would knock on the tree.

They believed the evil spirits could not hear their secret wishes if they knocked on the tree.

The Christian Cross

Some say the Christian cross is the reason for touching wood. The wooden cross is considered sacred.  During the Middle Ages people were a lot more superstition.

The wooden cross was acknowledged as quite effective to keep evil spirits at a distance.

Monks, wearing wood crosses were known to tap (knock on) the cross to ward off evil spirits lurking among their mists.

Tiggy Touch Wood

Touch Wood

“Tiggy touch wood” was an extremely well known children’s game in the early 19th century in Great Britain.

This was a chasing game.

The concept was that one was safe only when touching wood.

Often the children would shout “Tiggy, tiggy touch wood. I’ve got no wood.” to tease the chaser.

There is a theory that the phrase “touch wood” simply originated from this children’s game.

All were safe as soon as they would touch Wood.
