Thou Art Not Lovelier Than Lilacs

Thou art not lovelier than lilacs,-no,
  Nor honeysuckle; thou art not more fair
  Than small white single poppies,-I can bear
Thy beauty; though I bend before thee, though
From left to right, not knowing where to go,
  I turn my troubled eyes, nor here nor there
  Find any refuge from thee, yet I swear
So has it been with mist,-with moonlight so.
Like him who day by day unto his draught
  Of delicate poison adds him one drop more
Till he may drink unharmed the death of ten,
Even so, inured to beauty, who have quaffed
  Each hour more deeply than the hour before,
I drink-and live-what has destroyed some men.
