from paradise lost, john milton's epic catalog of the demons who became the gods of pagan peoples.  

1. Moloch
2. Chemos
3. Baalim
4. Ashtaroth
5. Astoreth/Astarte
6. Thammuz
7. Dagon
8. Rimmon
9. Osiris
10. Isis
11. Orus
12. Belial

for milton, as for homer and virgil, numbers are significant. these are the tribes of the demons, a new nation of evil. virgil has 12 foes for aeneas to defeat before the great battle for latium, so it makes sense that Christ would have 12 foes to defeat in his great fight. if my memory is right, the 13th foe that is listed for aeneas is not a part of the epic catalog, but is the most worthy opponent: turnus. similarly, perhaps Christ's most worthy opponent is listed 13th and outside the catalog: beelzebub. this leaves satan out of the picture, though, so obviously i need to think about it more.  

                 but he, my inbred enemy,

Forth issued, brandishing his fatal dart 

Made to destroy. I fled and cried out 'Death!'

Hell trembled at the hideous name, and sighed

From all her caves, and back resounded 'Death!'

john milton, paradise lost, II.785-789

A mind not to be changed by place or time. 

The mind is its own place and in itself

Can make a Heaven of hell, a hell of Heaven. 

john milton, paradise lost, I.253-255

lewis says much the same thing of the postmodern relativists: they will be the ones in the corners of hell saying "i just have to wake up... it's all in my mind, i just have to wake up." 

Fallen cherub, to be weak is miserable, 

Doing or suffering, but of this be sure, 

To do aught good never will be our task,

But ever to do ill our sole delight,

As being the contrary to his high will

Whom we resist. 

john milton, paradise lost, I.157-162

To bow and sue for grace 

With suppliant knee and deify his power, 

Who from the terror of this arm so late 

Doubted his empire, that were low indeed, 

That were an ignominy and shame beneath 

This downfall, since by fate the strength of gods 

And this empyreal substance cannot fail...

john milton, paradise lost, I.111-117
