The salt of the earth

Abstract

In earlier days sharing your salt with someone meant sharing your freindship, and the spilling of salt was taken as a sign that the friendship was going to end. However, salt has long been used as a protection against evil, and the throwing of salt over the shoulder cancels the evil effect of upsetting the salt.
