I have been one acquainted with the night.
I have walked out in rain—and back in rain.
I have outwalked the furthest city light.
I have looked down the saddest city lane.
I have passed by the watchman on his beat
And dropped my eyes, unwilling to explain.
I have stood still and stopped the sound of feet
When far away an interrupted cry
Came over houses from another street
But not to call me back or say good-bye;
And further still at an unearthly height
One luminary clock against the sky
Proclaimed the time was neither wrong nor right.
I have been one acquainted with the night.
Is this a literal clock, or a metaphor for the full moon? Critics have debated the point extensively, but Frost is now “acquainted with the night” as in “dead,” so we’ll never know for sure. 
 
 
 ACCEPTED COMMENT: Many have also thought that the “luminary clock” was referring to the Big Ben in London, the largest city in England, as Robert Frost spent a few years living in England. He wrote and published many poems while there, such as “The Road Not Taken”.
