Where does "only songs are beautiful, but beauty doesn't need songs" come from?

It should be from a poem by the Russian poet Fett, "At the sight of your smile ...", the last two sentences:

As soon as I saw your smile,

Or find your clear eyebrows—

Can sing love songs, but not for you,

But because of the beauty you never tire of seeing.

Whether in the morning or in the evening, people are talking about it.

That singer sings tirelessly,

Go to the cradle of her fragrance,

Like a nightingale crying at a rose.

But the young queen in the garden said nothing.

There is an appearance that shines with noble purity;

Only songs need beauty,

Beauty doesn't even need a song.

Russian original:

Афанасий Фет — Только встречу улыбку твою:

Только встречу улыбку твою

Или взгляд уловлю твой отрадный, —

Не тебе песнь любви я пою,

А твоей красоте ненаглядной.

Про певца по зарям говорят,

Будто розу влюбленною трелью

Восхвалять неумолчно он рад

Над душистой ее колыбелью.

Но безмолвствует, пышно чиста,

Молодая владычица сада:

Только песне нужна красота,

Красоте же и песен не надо.
