Analysis of Unnatural Love

Landor, not that I doubt your word,
That you had strove with none
At seventy-five and had deferred
To nature and art alone;
It is rather that at thirty-two
From us I see them part
After they served, so sweetly, you-
Yet nature has no heart:
Brother and sister are estranged
By his ambitious lies
For he his sister Helen much deranged-
Outraged her, and put coppers on her eyes.
