In Roman homes, salt shakers and wine barons were essential utensils for worship, and sometimes even used to invite Lars, the patron saint of the family. Salt, the most obvious object involved in the salt pot, symbolizes the wisdom and judgment inspired by the gods in the notes of the Bible.

Salt can represent excellent judgment, because it is necessary to accurately control the amount of salt in cooking. Too much or too little will destroy the taste of food. Because salt can protect food from decay, it is also considered to be a sign of resistance to evil spirits.
