Divine Comedy
This circle holds those who were violent in their lives. The people who were violent to people and property are in a river of fire. The depth of their placement in the river corresponds to how much you damaged in life. For example, Alexander the Great is immersed up to his eyebrows. The violent against self are turned into plants and are pecked at and ripped apart by birds. The violent to God and the violent to nature are also here. They have to walk on flaming sand for eternity.
