An example of a literary device used in the poem is irony.
Irony is when something unexpected happens, or something is said that is the opposite of what you’d expect. In this case, it is ironic that the sunsets were beautiful throughout the world because of the tragedy of the fire in Canada.
I know the dust of
gave the whole world
a year of fine sunsets.
The irony is that the destruction of the fire created the beauty of the sunset. Beauty from destruction is unexpected. The poem relies on the idea that the fire evokes these two different emotions of awe and sorrow.
By using this connection, the poet helps us feel intense emotion. The beauty of the sunset juxtaposed with the tragedy of the fire reinforces the idea that everything affects everything else.
