There are many monsters that a glassen surface
Restrains. And none more sinister
Than vision asleep in the eye’s tight translucence.
Rarely it seeks now to unloose
Its diamonds. Having divined how drab a prison
The purest mortal tissue is,
Rarely it wakes. Unless, coaxed out by lusters
Extraordinary, like the octopus
From the gloom of its tank half-swimming half-drifting
Toward anything fair, a handkerchief
Or child’s face dreaming near the glass, the writher
Advances in a godlike wreath
Of its own wrath. Chilled by such fragile reeling
A hundred blows of a boot-heel
Shall not quell, the dreamer wakes and hungers.
