There are surprisingly many good poems which are anonymous. These can be anonymous (unknown writer) for a variety of reasons and rarely impact upon their worth as a poem.
Poem:
This poem is listed as anonymous. however, I believe it to be by a poet named Barbara Burrow.
All things are ours because we love
The earth below, the sky above,
The mountains, meadow, sand, and sea.
All things surounding you and me
Are but a sweet reflection of
The gentle wonder of our love.
