To a Lady who Presented to the Author a Lock of Hair Braided with His Own And Appointed At a Night In December to meet him in The Garden -- Lord Byron
These locks, which fondly thus entwine,
In firmer chains our hearts confine,
Than all th' unmeaning protestations
Which swell with nonsense, love orations.
Our love is fix'd, I think we've prov'd it;
Nor time, nor place, nor art have mov'd it;
Then wherefore should we sigh and whine,
With groundless jealousy repine;
With silly whims, and fancies frantic,
Merely to make our love romantic?
Why should you weep, like Lydia Languish,
And fret with self-created anguish?
Or doom the lover you have chosen,
On winter nights to sigh half frozen;
In leafless shades, to sue for pardon,
Only because the scene's a garden?
For gardens seem, by one consent,
(Since Shakespeare set the precedent;
Since Juliet first declar'd her passion)
To form the place of assignation.
Oh! would some modern muse inspire,
And seat her by a sea-coal fire;
Or had the bard at Christmas written,
And laid the scene of love in Britain;
He surely, in commiseration,
Had chang'd the place of declaration.
In Italy, I've no objection,
Warm nights are proper for reflection;
But here our climate is so rigid,
That love itself, is rather frigid:
Think on our chilly situation,
And curb this rage for imitation.
Then let us meet, as oft we've done,
Beneath the influence of the sun;
Or, if at midnight I must meet you,
Within your mansion let me greet you:
'There', we can love for hours together,
Much better, in such snowy weather,
Than plac'd in all th' Arcadian groves,
That ever witness'd rural loves;
'Then', if my passion fail to please,
Next night I'll be content to freeze;
No more I'll give a loose to laughter,
But curse my fate, for ever after.
Romeo from Romeo Juliet, the balcony scene:
But soft! What light through yonder window breaks?
It is the East, and Juliet is the sun!
Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief(5)
That thou her maid art far more fair than she.
Be not her maid, since she is envious.
Her vestal livery is but sick and green,
And none but fools do wear it. Cast it off.
It is my lady; O, it is my love!(10)
O that she knew she were!
She speaks, yet she says nothing. What of that?
Her eye discourses; I will answer it.
I am too bold; 'tis not to me she speaks.
Two of the fairest stars in all the heaven,(15)
Having some business, do entreat her eyes
To twinkle in their spheres till they return.
What if her eyes were there, they in her head?
The brightness of her cheek would shame those stars
As daylight doth a lamp; her eyes in heaven(20)
Would through the airy region stream so bright
That birds would sing and think it were not night.
See how she leans her cheek upon her hand!
O that I were a glove upon that hand,/That I might touch that cheek
