Sonnet 17

No poem can capture the young man's true beauty; any verse about him will seem impossible to future readers and will be dismissed as the poet's exaggeration, unless the young man has a child who proves the poetry was truthful.

Original
Modern
1 Who will believe my verse in time to come
Who will believe my poetry in times to come
2 If it were filled with your most high deserts?
If it were full of your greatest gifts?
'Deserts' = merits, worthiness; 'high' = lofty, supreme.
3 Though yet heaven knows it is but as a tomb
Though heaven knows it's only like a tomb
'Tomb' = grave; metaphor for how verse cannot preserve true beauty, only entomb it.
4 Which hides your life, and shows not half your parts:
Which hides your life, and doesn't even show half your qualities:
'Parts' = qualities, excellences.
5 If I could write the beauty of your eyes,
Had I the skill to paint your eyes in words,
6 And in fresh numbers number all your graces,
To catalog every quality that makes you remarkable,
'Numbers' = verses, poetry; 'graces' = virtues, excellences; punning on 'number.'
Wordplay: “And in fresh numbers number all your graces”
  • numbers = verses, poetry
  • number = to enumerate, to count
  • the pun creates a self-reflexive statement: poetry counts and enumerates beauty through verse itself
7 The age to come would say this poet lies,
Future generations would call this poet a liar,
8 Such heavenly touches ne’er touched earthly faces.
Such heavenly touches never touched earthly faces.
'Heavenly touches' = divine beauty; 'earthly faces' = mortal, human appearance.
9 So should my papers (yellowed with their age)
So my papers (yellowed with age)
10 Be scorned, like old men of less truth than tongue,
Would be mocked, like old men who talk more than they mean,
Comparison of outdated poems to garrulous old men full of false tales.
11 And your true rights be termed a poet’s rage,
And your real qualities called a poet's madness,
'True rights' = genuine merits; 'rage' = passionate exaggeration, madness.
12 And stretched metre of an antique song.
And the stretched meter of an old song.
'Stretched metre' = verse artificially extended to fit hyperbolic claims.
Volta The volta shifts from the hopelessness of poetry capturing truth to the redemptive solution: a child of the young man becomes the living validation of the poet's truthful verse.
13 But were some child of yours alive that time,
But if some child of yours was alive at that time,
14 You should live twice,—in it, and in my rhyme.
The resolution of the procreation sequence: the young man achieves double immortality through his child and the poet's verse.
You would live twice—in your child, and in my poetry.
Double immortality: biological (child) and literary (verse).
The Crisis of Poetic Credibility

Sonnet 17 grapples with a problem unique to love poetry: excess of truth. If the speaker praises the young man's beauty hyperbolically, future readers will think it's flattery. But if the beauty is genuinely transcendent, no poem can capture it. This creates a logical trap: either the poet lies (by praising beyond reality) or the poem fails (by understating reality). The resolution is ingenious—a child inheriting the young man's beauty becomes living proof that the poetry was truthful, not exaggeration.

Manuscript as Tomb: The Anxiety of Preservation

The image of yellowed papers mocked by future generations invokes the speaker's deep anxiety about time and memory. Verse, which claims to preserve, becomes itself a victim of time: papers yellow, ink fades, language becomes archaic. This terror of obsolescence propels the later argument (sonnets 18–28) that verse can indeed defeat time, but only if it's written with such clarity and power that it remains eternally readable and relevant. Immortality is not automatic; it must be earned through genius.

If this happened today

Imagine an artist painting their partner as impossibly perfect. Future viewers would say the painting is unrealistic flattery. But if the couple had children who inherited that beauty, those kids become living proof: 'Oh, the painting wasn't exaggerated after all.' The speaker is saying: your beauty is so great that no poem can make it believable without a child to corroborate it.
