O SILVER-THROATED Swan
Struck, struck! A golden dart
Clean through thy breast has gone
Home to thy heart.
Thrill, thrill, O silver throat!
O silver trumpet, pour
Love for defiance back
On him who smote!
And brim, brim o'er
With love; and ruby-dye thy track
Down thy last living reach
Of river, sail the golden light—
Enter the sun's heart—even teach
O wondrous-gifted Pain, teach Thou
The God of love, let him learn how
Thomas Sturge Moore
