I need to write an essay comparing two of the following poems by W.B. Yeats in regards to context, themes, and so on to an unseen question. "When You Are Old" "The Second Coming" "Leda And The Swan" "Easter 1916" "The Wild Swans At Coole" "Among School Children" "An Irish Airman Foresees His Death" My question is which poems work well with each other and why? Thank you :)

Yeats's work moves in two directions, in a way. Much of what he says in his poetry is very Romantic. "The Wild Swans at Coole" represents this well. In the poem, he paints a vivid nature scene and ponders the value of beauty.
An obvious connection can be made to "Leda and the Swan," of course, but it would be more of a contrast than a comparison. The swan in the latter is representative of brutality, the "brute blood of the air," as he calls it. Its beauty makes the rape of Leda that much more of a betrayal since one would normally associate swans with grace and gentleness. Still, a meaningful analysis of how he uses the beauty of the animal in both could yield some insightful ideas, even if he takes the symbolic bird in two very different directions.
The idea of Leda repeats itself in "Among School Children," in the second stanza. The speaker "dream[s] of a Ledaean body," he says in the second stanza, and he ponders the fragile innocence of the children he sees, referring once again to swans in the third stanza. Though this poem's narrative takes place in the real, contemporary world of the poet and "Leda and the Swan" is a recall of the classical Greek myth, both explore some rather ugly human realities. Both poems offer a cynical sadness in their points of view.
"The Second Coming," and "Easter, 1916" also take a very modern, somewhat pessimistic view of human society, and these two both build heavily on the trope of birth. In "Easter, 1916," Yeats discusses three times a "terrible beauty [being] born," and in "The Second Coming," he ends the poem on the image of a "rough beast . . . slouch[ing] toward Bethlehem to be born." Both explore a dire possibility for the future, and both offer a subtle (if slim) chance for hope.
"When You are Old" and "An Irish Airman Foresees his Death" are both outliers (in my opinion), the former being a very personal expression of love and the latter being an expression of Irish nationalism. The second may be compared to some of the other more cynical poems, but the target is a specific political subject matter: Irish soldiers dying as soldiers for the UK, whereas in the others he deals with broader patterns of human life.
