From The Arabic, An Imitation Poem by Percy Bysshe Shelley

MY faint spirit was sitting in the light
   Of thy looks, my love;
   It panted for thee like the hind at noon
   For the brooks, my love.
Thy barb, whose hoofs outspeed the tempest's flight,
   Bore thee far from me;
   My heart, for my weak feet were weary soon,
   Did companion thee.

Ah! fleeter far than fleetest storm or steed,
   Or the death they bear,
   The heart which tender thought clothes like a dove
   With the wings of care;
In the battle, in the darkness, in the need,
   Shall mine cling to thee,
   Nor claim one smile for all the comfort, love,
   It may bring to thee.
