I.
When a lover clasps his fairest,
Then be our dread sport the rarest.
Their caresses were like the chaff
In the tempest, and be our laugh
His despair—her epitaph!
II.
When a mother clasps her child,
Watch till dusty Death has piled
His cold ashes on the clay;
She has loved it many a day--
She remains,—it fades away.
Percy Bysshe Shelley
