No poet felt this ecstasy of mere living in Nature more deeply than Browning.

His own rapture (the word is not too strong) in it appears again and again in his poetry, and when it does, Browning is not a man sympathising from without with Nature.

He is then a part of Nature herself, a living piece of the great organism, having his own rejoicing life in the mightier life which includes him; and feeling, with the rest, the abounding pleasure of continuous life reaching upwards through growth to higher forms of being, swifter powers of living.

I might give many examples, but one will suffice, and it is the more important because it belongs not to his ardent youth, but to his mature manhood.

It is part of the song of Thamyris in _Aristophanes' Apology_.
