Sailing to Byzantium Yeats 1928
I interpret the poem as a trip from the beginning of the life up to the end of the life.
In the first stanza Yeats speaks about his ground of birth: "That is no country for old men." He speaks about the nature and he says that quite what is born, it dies. In the second stanza, I think that he ponders on board of the ship. In the third stanza, Yeats looks amazed at the mosaic of the wise people, which they teach to the soul of the people. Also Yeats in this stanza does a request to the wise people; he says to them that they should take it with them towards the immortality.
In the fourth stanza, Yeats speaks about a trip after the death, coming this way to the immortality. He says that the nature is a life, it is the change and the death is the eternity.
