The Couple
The poem focuses on the relationship between a couple. It is clear from the speaker's casual use of “we” and “us” that they have been together for some time. The speaker—whose gender is not indicated—describes taking advantage of a break in a two-day rain spell to take a walk. The suggestion of an argument or disagreement hangs heavily upon them. They silently make their way around a lake, walking with a gap between them.
The Swans
The beauty of the swans moving together in the water stops the couple in their tracks. Their performance of tipping their heads and "[halving] themselves in the dark water" has a profound effect on the couple (Line 10). Described as "icebergs of white feather," the swans' significance extends beyond what can be immediately seen (Line 11). As they leave the scene, they are depicted as "porcelain over the stilling water" (Line 14). Despite having a fragile appearance, porcelain is quite strong. As they watch the swans, the couple is taken out of the context of their own problems. Ultimately they are left with the possibility of reconciliation. Overall, the swans exemplify the healing capability of the natural world.
