Analysis of By A Grave

Oft have I stood within the carven door
Of some cathedral at the close of the day,
And seen its softened splendors fade away
From lucent pane and tessellated floor,
As if a parting guest who comes no more,
Till over all silence and blackness lay,
Then rose sweet murmurings of them that pray,
And shone the altar lamps unseen before,
So, Dear, as here I stand with thee alone,
The voices of the world sound faint and far,
The glare and glory of the moon grow dim,
And in the stillness, what I had not known,
I know, a light, pure shining as a star,
A song, uprising like a holy hymn.
