Fragment: "Igniculus Desiderii"

To thirst and find no fill, -- to wail and wander
With short unsteady steps, -- to pause and ponder, --
To feel the blood run through the veins and tingle
Where busy thought and blind sensation mingle, --
To nurse the image of unfelt caresses
Till dim imagination just possesses
The half-created shadow, then all the night
Sick . . .

                                 —Percy Bysshe Shelley
