Analysis of Grey Hours: Naples

There are some hours when I seem so indifferent; all things fade
To an indifferent greyness, like that grey of the sky;
Always at evening-ends, on grey days; and I know not why,
But life, and art, and love, and death, are the shade of a shade.
Then, in those hours, I hear old voices murmur aloud,
And memory forgoes desire, too weary at heart for regret;
Dreams come with beckoning fingers, and I forget to forget;
The world as a cloud drifts by, or I drift by as a cloud.
