This poem discusses the lasting impact of the death of the poet's wife 18 years ago. He is kept awake at night by memories of her, seeing her gentle face looking at him from a picture on the wall. A halo of light surrounds her head. She died in this very room from burns suffered in a fire. Though 18 years have passed, he still wears the "cross" of her death on his breast, unchanged through all the seasons, just as a cross of snow remains unchanged on a mountain in the distant West. The memory and love for his late wife remains as deeply enduring for the poet as that cross of snow on the mountainside.
