This paper uses several in-text citations from various cited sources to clearly explain the imagery of Robert Hayden's "Those Winter Sundays."
From the Paper:
"Hayden's poem begins with images of the freezing weather to create a literal feeling of coldness within the home. In the first stanza the weather is described as being "blueblack cold". The use of the word "blueblack" to describe the cold conjures up several images in the mind of the reader. First, the word "blue" shows the intensity of the icy weather. The "blueness" of the weather creates the image of icy, frozen conditions, and enables the reader to imagine how cold "those winter Sundays" must have been. In addition the word "black", which is used to describe the weather, creates an image of darkness associated with the cold. The darkness of the mornings lets the reader know that there is an absence of all sunlight and, hence, all warmth within the home."
