What lips my lips have kissed, and where, and why,
I have forgotten, and what arms have lain
Under my head till morning; but the rain
Is full of ghosts tonight, that tap and sigh
Upon the glass and listen for reply,
And in my heart there stirs a quiet pain
For unremembered lads that not again
Will turn to me at midnight with a cry.
Thus in winter stands the lonely tree,
Nor knows what birds have vanished one by one,
Yet knows its boughs more silent than before:
I cannot say what loves have come and gone,
I only know that summer sang in me
A little while, that in me sings no more.

Love is not all: it is not meat nor drink
Nor slumber nor a roof against the rain; 
Nor yet a floating spar to men that sink 
And rise and sink and rise and sink again; 
Love can not fill the thickened lung with breath, 
Nor clean the blood, nor set the fractured bone; 
Yet many a man is making friends with death 
Even as I speak, for lack of love alone. 
It well may be that in a difficult hour, 
Pinned down by pain and moaning for release, 
Or nagged by want past resolution’s power, 
I might be driven to sell your love for peace, 
Or trade the memory of this night for food. 
It well may be. I do not think I would.

Him rival to the gods I place,
   Him loftier yet, if loftier be,
Who, Lesbia, sits before thy face,
   Who listens and who looks on thee;

Thee smiling soft. Yet this delight
   Doth all my sense consign to death;
For when thou dawnest on my sight,
   Ah, wretched! flits my labouring breath.

My tongue is palsied. Subtly hid
   Fire creeps me through from limb to limb:
My loud ears tingle all unbid:
   Twin clouds of night mine eyes bedim.

Ease is my plague: ease makes thee void,
   Catullus, with these vacant hours,
And wanton: ease that hath destroyed
   Great kings, and states with all their powers.
