Question

The message that poet want to convey through the poem snake

Answer 1

The snake comes across as an invasive and arresting threat comparable to the famous serpent in the Genesis story in The Bible, especially in the contrast Wright's words make between the walkers' calm, warm world and the snake's active, cold one.  The sibilant words in the opening line, "Sun-warmed in this late seasons' grace", establishes a relaxed warm mood which the snake penetrates: it "froze" the walkers mid-stride.  In addition, the word "Cold" has a heavy effect at the start of the final stanza, which leaves a final impression of the snake's potent presence.  However, unlike the biblical snake, this one ultimately fails to gain dominance over the walkers.
