Variation on a Theme by Collins br br Let the day glare: O memory, your tread br Beats to the pulse of suffocating night- br Night peering from his dark but fire-lit head br Burns on the day his tense and secret light. br br Now they dare not to gloss your savage dream, br O beast of the heart, those saints who cursed your name; br You are the current of the frozen stream, br Shadow invisible, ambushed and vigilant flame. br br My eldest companion present in solitude, br Watch-dog of Thebes when the blind hero strove: br You, omniscient, at the cross-roads stood br When Laius, the slain dotard, drenched the grove. br br Now to the eye of prophecy immune, br Fading and harried, you stalk us in the street br From the recesses of the August noon, br Alert world over, crouched on the air's feet. br br You are our surety to immortal life, br God's hatred of the universal stain- br The heritage, O Fear, of ancient strife br Compounded with the tissue of the vein.
