Introduction
Sonnet 18 deserves its fame because it is one of the most beautifully written verses in the English language. The sonnets endurance comes from Shakespeares ability to capture the essence of love so cleanly and succinctly.
After much debate amongst scholars, it is now generally accepted that the subject of the poem is male. In 1640, a publisher called John Benson released a highly inaccurate edition of Shakespeares sonnets in which he edited out the young man, replacing he with she.
Bensons revision was considered to be the standard text until 1780 when Edmond Malone returned to the 1690 quarto and re-edited the poems. Scholars soon realized that the first 126 sonnets were originally addressed to a young man sparking debates about Shakespeares sexuality. The nature of the relationship between the two men is highly ambiguous and it is often impossible to tell if Shakespeare is describing platonic love or erotic love.
Commentary
The opening line poses a simple question which the rest of the sonnet answers. The poet compares his loved one to a summers day and finds him to be more lovely and more temperate.
The poet discovers that love and the mans beauty are more permanent than a summers day because summer is tainted by occasional winds and the eventual change of season. While summer must always come to an end, the speakers love for the man is eternal.
For the speaker, love transcends nature in two ways:
- The speaker begins by comparing the mans beauty to summer, but soon the man becomes a force of nature himself. In the line, thy eternal summer shall not fade, the man suddenly embodies summer. As a perfect being, he becomes more powerful than the summers day to which he was being compared.
- The poets love is so powerful that even death is unable to curtail it. The speakers love lives on for future generations to admire through the power of the written word through the sonnet itself. The final couplet explains that the beloveds eternal summer will continue as long as there are people alive to read this sonnet:
So long as men can breathe or eyes can see,
So long lives this, and this gives life to thee.
The young man to whom the poem is addressed is the muse for Shakespeares first 126 sonnets. Although there is some debate about the correct ordering of the texts, the first 126 sonnets are thematically interlinked and demonstrate a progressive narrative. They tell of a romantic affair that becomes more passionate and intense with each sonnet.
In previous sonnets, the poet has been trying to convince the young man to settle down and have children, but in Sonnet 18 the speaker abandons this domesticity for the first time and accepts loves all-consuming passion a theme that is set to continue in the sonnets that follow.
