Or walls of cold, unsympathetic stone
Respond but hollow echoes of a groan.
Though limbs as free and restless as the wind
Are not to shackles readily resigned,
Complaint, with oath and bitterness replete,
In prisoner is doubly indiscreet.
The imprecation, born of righteous wrath,
Subtracts no obstacle from any path.
Bereft of star or luminary bright,
No night so dark as artificial night;
