The serpent slithered through the grass,
First to Eve, the mistress of Eden,
And made her cross with what it told.
When first Adam heard of what had occurred,
"You silly hen!" he chided his wife.
But all too late; 'twas the end of the end.
As though with the prick of a thorn,
Knowledge finally came to them both.
Clearly now they could see,
With the eyes God had made them,
That at last they'd lost
And this was their final day.
