The widespread superstition that spilling salt brings bad luck is believed to have originated with the overturned salt cellar in front of Judas Iscariot at the Last Supper, an incident immortalized in Leonardo Da Vinci’s famous painting.
According to an old Norwegian superstition, a person will shed as many tears as will be necessary to dissolve the salt spilled. An old English belief has it that every grain of salt spilled represents future tears. The Germans believe that whoever spills salt arouses enmity, because it is thought to be the direct act of the devil, the peace disturber. The French throw a little spilled salt behind them in order to hit the devil in the eye, to temporarily prevent further mischief. In the United States, some people not only toss a pinch of spilled salt over the left shoulder, but crawl under the table and come out the opposite side.
