Mammon is a concept as old as the Bible having to do with greed, avarice, and materialism in the Old Testament. In the New Testament, the concept is personified as a false god. Mammon is latter referred to in various literary works, including the Divine Comedy, as the demon that personifies the avarice, one of the seven deadly sins.
