Read "Villanelle of My Lady's Treasures" by Ernest Christopher Dowson. Then, answer the question that follows.

I took her dainty eyes, as well
As silken tendrils of her hair:
And so I made a Villanelle!

I took her voice, a silver bell,
As clear as song, as soft as prayer;
I took her dainty eyes as well.

It may be, said I, who can tell,
These things shall be my less despair?
And so I made a Villanelle!

I took her whiteness …
And from her cheek two roses rare:
I took her dainty eyes as well.

I said: "It may be possible
Her image from my heart to tear!"
And so I made a Villanelle.

I stole her laugh, most musical:
I wrought it in with artful care;
I took her dainty eyes as well;
And so I made a Villanelle.

How does the form of the villanelle impact the meaning of Dowson's poem?
Fourteen lines are divided into an octave about painting a portrait and a sestet about villanelles.
Repetition of two lines throughout emphasizes that the beauty of the speaker's subject could only be painted through a villanelle.
There is no rhyme scheme or meter, which makes the poem seem like an informational paragraph about painting portraits.
The shift and the couplet explain that the subject of the poem is very nice, and only a poem can express that.
