In a forest, laurel-greened
as Eocene Elysium,
neither shackled or demeaned
dwelt Hyracotherium.
Thirty million years passed
and scion Merychippus
grazed unbounded plains of grass,
Miocene terra nullius.
Twenty million years passed
and human hocus-pocus
enslaved to a servile caste
descendent Equus Caballus.
Zebras flaunting black and white
defy the upstart midgets,
Equus Burchelli in full flight
flipping their middle digits.
Just as well, that Man tamed horse
to serve Apocalyptic bile,
else Four Horsemen would perforce
ride sans steeds in Gangnam Style.
