The cuckoo-throb, the heartbeat of the Spring;
The rosebud's blush that leaves it as it grows
Into the full-eyed fair unblushing rose;
The summer clouds that visit every wing
With fires of sunrise and of sunsetting;
The furtive flickering streams to light re-born
'Mid airs new-fledged and valorous lusts of morn,
While all the daughters of the daybreak sing:—
These ardour loves, and memory: and when flown
All joys, and through dark forest-boughs in flight
The wind swoops onward brandishing the light,
Even yet the rose-tree's verdure left alone
Will flush all ruddy though the rose be gone;
With ditties and with dirges infinite.

Dante Gabriel Rossetti
