A Short Analysis of Shakespeare’s Sonnet 18: ‘Shall I compare thee to a summer’s day?’
A summary of a classic Shakespeare poem
‘Shall I compare thee to a summer’s day?’ is one of the most famous opening lines in all of literature. In this post, we’re going to look beyond that opening line, and the poem’s reputation, and attempt a short summary and analysis of Sonnet 18 in terms of its language, meaning, and themes. The poem represents a bold and decisive step forward in the sequence of Sonnets as we read them. For the first time, the key to the Fair Youth’s immortality lies not in procreation (as it had been in the previous 17 sonnets) but in Shakespeare’s own verse. But what is William Shakespeare’s Sonnet 18 actually saying?
Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer’s lease hath all too short a date:
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimmed,
And every fair from fair sometime declines,
By chance, or nature’s changing course untrimmed:
But thy eternal summer shall not fade,
Nor lose possession of that fair thou ow’st,
Nor shall death brag thou wander’st in his shade,
When in eternal lines to time thou grow’st,
So long as men can breathe, or eyes can see,
So long lives this, and this gives life to thee.
Most of the poems we write about here on Interesting Literature involve introducing the unfamiliar: we take a poem that we think has something curious and little-known about it, and try to highlight that feature, or interpretation. But with ‘Shall I compare thee to a summer’s day?’ we have almost the opposite problem: we’re trying to take a very well-known poem and de-familiarise it, and try to see it as though we’re coming across it for the first time. This is by no means an easy task, so we’ll begin with a summary.
First, then, that summary of Sonnet 18, beginning with that opening question, which sounds almost like a dare or a challenge, nonchalantly offered up: ‘Shall I compare thee to a summer’s day?’ Shakespeare asks the addressee of the sonnet – who is probably the same young man, or ‘Fair Youth’, to whom the other early sonnets are also addressed – whether he should compare him to a summery day. He goes on to remark that the young man is lovelier, and more gentle and dependably constant. After all, in May (which, in Shakespeare’s time, was considered a bona fide part of summer) rough winds often shake the beloved flowers of the season (thus proving the Bard’s point that summer is less ‘temperate’ than the young man). What’s more, summer is over all too quickly: its ‘lease’ – a legal term – soon runs out. We all know this to be true, when September rolls round, the nights start drawing in, and we get that sinking ‘back to school’ feeling.
In lines 5-8, Shakespeare continues his analysis of the ways in which the young man is better than a summer’s day: sometimes the sun (‘the eye of heaven’) shines too brightly (i.e. the weather is just too hot, unbearably so), and, conversely, sometimes the sun is ‘dimmed’ or hidden by clouds. And every lovely or beautiful thing (‘fair’ here in ‘every fair’ is used as a noun, i.e. ‘every fair thing’), even the summer, sometimes drops a little below its best, either randomly or through the march of nature (which changes and in time ages every living thing).
In lines 9-12, Shakespeare continues the ‘Youth vs. summer’ motif, arguing that the young man’s ‘eternal summer’, or prime, will not fade; nor will the Youth’s ‘eternal summer’ lose its hold on the beauty the young man owns (‘ow’st’). Nor will Death, the Grim Reaper, be able to boast that the young man walks in the shadow of death, not when the youth grows, not towards death (like a growing or lengthening shadow) but towards immortality, thanks to the ‘eternal lines’ of Shakespeare’s verse which will guarantee that he will live forever.
In his concluding couplet, Shakespeare states that as long as the human race continues to exist, and read poetry, Shakespeare’s poem (‘this’) survives, and continues to ‘give life’ to the young man through keeping his memory alive.
Sonnet 18 is a curious poem to analyse when it’s set in the context of the previous sonnets. It’s the first poem that doesn’t exhort the Fair Youth to marry and have children: we’ve left the ‘Procreation Sonnets’ behind. In the last few sonnets, Shakespeare has begun to introduce the idea that his poetry might provide an alternative ‘immortality’ for the young man, though in those earlier sonnets Shakespeare’s verse has been deemed an inferior way of securing the young man’s immortality when placed next to the idea of leaving offspring. In Sonnet 18, right from the confident strut of ‘Shall I compare thee to a summer’s day?’ onwards, Shakespeare is sure that his poetry will guarantee the young man his immortality after all.
There is an easy music to the poem, set up by that opening line: look at repetition of ‘summer’ and ‘some’, which strikes us as natural and not contrived, unlike some of the effects Shakespeare had created in the earlier sonnets: ‘summer’s day’, ‘summer’s lease’, ‘Sometime too hot’, ‘sometime declines’, ‘eternal summer’. This reinforces the inferiority of the summer with its changeability but also its brevity (‘sometime’ in Shakespeare’s time meant not only ‘sometimes’, suggesting variability and inconstancy, but also ‘once’ or ‘formerly’, suggesting something that is over). In terms of imagery, the reference to Death bragging ‘thou wander’st in his shade’, as well as calling up the words from the 23rd Psalm (‘Yea, though I walk through the valley of the shadow of death’), also fits neatly into the poem’s broader use of summer/sun imagery. As Stephen Booth points out in the detailed notes to this sonnet in his indispensable edition Shakespeare’s Sonnets (Yale Nota Bene), the brightness of that all-too-fleeting summer’s day has been declining ever since the poem’s opening line: ‘dimmed’, ‘declines’, ‘fade’, ‘shade’.
Sonnet 18 has undoubtedly become a favourite love poem in the language because its message and meaning are relatively easy to decipher and analyse. Its opening line has perhaps eclipsed the rest of the poem to the degree that we have lost sight of the precise argument Shakespeare is making in seeking to compare the Youth to a summer’s day, as well as the broader context of the rest of the Sonnets and the implications this has for our interpretation of Sonnet 18. The poem reveals a new confidence in Shakespeare’s approach to the Sonnets, and in the ensuing sonnets he will take this even further.
