Countee Cullen, from Color (Harper, 1925):
Locked arm in arm they cross the way
The black boy and the white,
The golden splendor of the day
The sable pride of night.
From lowered blinds the dark folk stare
And here the fair folk talk,
Indignant that these two should dare
In unison to walk.
Oblivious to look and word
They pass, and see no wonder
That lightning brilliant as a sword
Should blaze the path of thunder.
