What is the author's style in Ithaka by Constantine P. Cavafy?

Although the island of Ithaka will always be associated with the homeland of Odysseus, in this poem, Cavafy uses the place name in an additional sense. Just as the journey to Ithaka is a metaphor for the human journey through life, so Ithaka is a metaphor for all destinations. It represents all the goals and ideals that humans strive for, all the expectations of a reward to be received in the future for actions performed in the present. This metaphorical meaning of Ithaka is clear not only from the context in which the word is used but also because the last line refers to Ithaka not in the singular but in plural, "Ithakas."
