"It's A Long Lane That Knows No Turnings"

Context: The narrator of this poem is a servant of an Italian duke who had ordered a young woman withdrawn from a convent that he could take her as his wife. She finds that the routine of the duke's household and the domination of his sickly mother make life dismal and burdensome for her; a few months after her marriage she seizes an opportunity to escape and is never seen again. This incident had happened many years before, and now the servant anticipates the time when the old duke's death will end his bond of servitude. He will make the most of his freedom, but his time is short. His wife, Jacynth, and his children are dead and he knows that all human situations, and all human lives, come to an end:

. . . in the churchyard Jacynth reposes,
And our children all went the way of the roses:
It's a long lane that knows no turnings.
