Without reflection, without mercy, without shame,
they built strong walls and high, and compassed me about.
And now I sit here and consider and despair.
My brain is worn with meditating on my fate:
I had outside so many things to terminate.
Oh! why when they were building did I not beware!
But never a sound of building, never an echo came.
Out of the world, insensibly, they shut me out.
(“Walls” Poem by C. P. Cavafy)
