Percy Bysshe Shelley: Lines ("Far, far away, O ye Halcyons of Memory")

1.
Far, far away, O ye
Halcyons of Memory,
Seek some far calmer nest
Than this abandoned breast!
No news of your false spring
To my heart's winter bring,
Once having gone, in vain
Ye come again.

2.
Vultures, who build your bowers
High in the Future's towers,
Withered hopes on hopes are spread!
Dying joys, choked by the dead,
Will serve your beaks for prey
Many a day.
