These simple children of the sun and soil.
O black slave singers, gone, forgot, unfamed,
You—you alone, of all the long, long line
Of those who've sung untaught, unknown, unnamed,
Have stretched out upward, seeking the divine.
You sang not deeds of heroes or of kings;
No chant of bloody war, no exulting pean
Of arms-won triumphs; but your humble strings
You touched in chord with music empyrean.
You sting far better than you knew; the songs
That for your listeners' hungry hearts sufficed
Still live,—but more than this to you belongs:
You sang a race from wood and stone to Christ.
Johnson ends by essentially thanking these unknown artists for mentally and spiritually freeing an oppressed population. 

O Black and Unknown Bards
