The Nine Rings of Hell

In case you were wondering, here's what Dante said (good page here):

1. Limbo
Unbaptized babies and pagans who never had a chance

2. Lust
People driven by their fleshly desires in life

3. Gluttony
People who overindulged in food and drink

4. Greed
Those who hoarded possessions and those who overspend

5. Anger
The wrathful

6. Heresy
Those who had beliefs that contradicted those of the church

7. Violence
Murderers, suicides, blasphemers and rapists of the same sex

8. Liars
Panderers and seducers, flatterers, those who buy church offices, sorcerers and false prophets, corrupt politicians, hypocrites, evil counselors, the divisive, perjurers, [and surrogates for presidential candidates... just kidding]

9. Treachery
Those who betrayed their closest friends and family, including Judas
