Not only was Leonardo DaVinci a great painter, he knew some things about salt that I just discovered. Of all the times I looked at this "Last Supper Painting" I never noticed there was salt on the table.

In Bible times, salt was used symbolically in covenants - in both Old Testament and New. Jehovah entered into a salt covenant with David that his seed would be on the throne forever. In Jesus' time, Roman soldiers carried pouches of salt, and when they made a covenant they would pour salt from their pouches into one container and shake it up. Then who could tell one man's salt from the other?

A salt covenant symbolizes:

Loyalty

Honesty

Friendship

Preservation

Now, take a peek at this close up of Judas from "The Last Supper" painting.

Not only does he have a bag in his hand, while the other reaches toward the bowl, but the salt is spilled in front of his arm.... symbolizing the broken covenant between him and Jesus.
