What metaphor does Caesar use when he characterizes himself on the Ides of March?

"I know he would not be a wolf, but that he sees the Romans are but sheep:

He were no lion, were not Romans hinds."

Casca describes Caesar in this way; Caesar is like the lion or the wolf, and the citizens of Rome are likened to sheep. I will look further for a description of Caesar about himself, but I don't think there is one.

At the Senate in the Ides of March, when asked if he will repeal the banishment of Publius Cimber, Caesar becomes enraged. In a dramatic monologue, Caesar compares himself to the Northern Star and denies the petition, thus sealing his fate. Cimber is the brother of conspirator Metullus, and had Caesar granted the request, he might have changed the course of history. I believe jill d's quote came from Cassius, not Cascade, during the storm on the eve of Caesar's death.

The skies are painted with unnumber’d sparks,  

They are all fire and every one doth shine,   72

But there’s but one in all doth hold his place:  

So, in the world; ’tis furnish’d well with men,  

And men are flesh and blood, and apprehensive;  

Yet in the number I do know but one   76

That unassailable holds on his rank,  

Unshak’d of motion: and that I am he,  

Let me a little show it, even in this,  

That I was constant Cimber should be banish’d,

That would be Casca, not Cascade.
