Great Caesar's Ghost

I saw you standing there.
Your shadow covers so much ground around my feet and arms and back.
I can't look up, my eyes are too tired, my head is stiff from the same position.
My name is lost in the mass of general memory,
But yours is on the tip of my tongue.
Great Caesar's Ghost.
I have the Brutus urge,
and power is nothing a knife can't quell.
