DEAD COW FARM by ROBERT GRAVES

An ancient saga tells us how
In the beginning the First Cow
(For nothing living yet had birth
But elemental Cow on Earth)
Began to lick cold stones and mud:
Under her warm tongue flesh and blood
Blossomed, a miracle to believe;
And so was Adam born, and Eve.
Here now is chaos once again,
Primaeval mud, cold stones and rain.
Here flesh decays and blood drips red
And the Cow's dead, the old Cow's dead.
