Henry Wadsworth Longfellow - Sleep

Lull me to sleep, ye winds, whose fitful sound
Seems from some faint Aeolian harp-string caught;
Seal up the hundred wakeful eyes of thought
As Hermes with his lyre in sleep profound
The hundred wakeful eyes of Argus bound;
For I am weary, and am overwrought
With too much toil, with too much care distraught,
And with the iron crown of anguish crowned.
Lay thy soft hand upon my brow and cheek,
O peaceful Sleep! until from pain released
I breathe again uninterrupted breath!
Ah, with what subtle meaning did the Greek
Call thee the lesser mystery at the feast
Whereof the greater mystery is death!

Henry Wadsworth Longfellow
