Men improve with the years

I AM worn out with dreams
A weather-worn, marble triton
Among the streams
And all day long I look
Upon this lady's beauty
As though I had found in a book
A pictured beauty,
pleased to have filled the eyes
Or the discerning ears,
Delighted to be but wise,
For men improve with the years
And yet, and yet,
Is this my dream, or the truth?
O would that we had met
When I had my burning youth!
But I grow old among dreams,
A weather-worn, marble triton
Among the streams.
