The two most popular explanations of origin are that the belief goes back to pagan times when we believed in tree spirits, or that we are invoking Christ’s protection by referring to the wood of the Cross. The former is nothing but guesswork, based on the conviction that all superstitions must be ancient, and it has the usual problem of spanning thousands of years with no evidence at all of its existence, or, for that matter, any evidence that ‘we’ ever believed in tree spirits.
