William Shakespeare wrote sonnet 116. In this sonnet, Shakespeare tries to elucidate love by using comparisons, metaphors, and personification. The theme of this sonnet is about true love because of Shakespeare's ability to describe all different definitions of love, and why it is so essential to human beings.
There is a lot of metaphors in the poem. Shakespeare compares love to an ever-fixed mark, leading the ships like the North Star. In the poem, the ships represent the human beings lost in the search for life’s true meanings.
This metaphor makes the message more transparent because you can imagine the star guiding the lost sailors in the middle of the ocean and you understand the meaning of the words in another way than if he had just written: “love is priceless.”
