"On the Creation of Niggers" (1912)
When, long ago, the gods created Earth,
In Jove's fair image Man was shaped at birth.
The beasts for lesser parts were next designed;
Yet were they too remote from humankind,
To fill the gap, and join the rest to Man,
Th'Olympian host conceived a clever plan.
A beast they wrought, in semi-human figure,
Filled it with vice, and called the thing a NIGGER.
