Her Strong Enchantments Failing, by A. E. Houseman

Her strong enchantments failing,
 Her towers of fear in wreck,
Her limbecks dried of poisons
 And the knife at her neck, 

The Queen of air and darkness
 Begins to shrill and cry,
"O young man, O my slayer,
 To-morrow you shall die."

O Queen of air and darkness,
 I think 'tis truth you say,
And I shall die tomorrow;
 But you will die to-day.
