Simile is used in Shakespeare's Romeo and Juliet at the beginning of Act 1.4.
Romeo, Mercutio, Benvolio (of the house of Montague) and others are in the process of entering the house of Capulet to join a party. The boys, who are "crashing" the party, are joking about whether they should be announced or should just enter without apology.
We'll have no Cupid hoodwinked with a scarf [no blind Cupid introducing them--the presenter at events like this would sometimes be dressed as Cupid],
Bearing a Tartar's painted bow of lath [a bow shorter than the traditional English long bow],
Scaring the ladies like a crowkeeper,...
Crowkeeper is simply a scarecrow. Thus, Benvolio says that the boys will not be introduced at the party by a presenter dressed like Cupid, carrying a small bow, who will scare the ladies like a scarecrow scares crows. That is a simile.
The presenter scaring the ladies is compared by the use of the word, like, to a scarecrow scaring crows.
One of my favorite similes in Romeo and Juliet occurs in the balcony scene: Act II, scene ii:
A thousand times the worse, to want thy light.
Love goes toward love, as schoolboys from
But love from love, toward school with heavy looks.
The comparison occurring here states that two people in love with each other are drawn dramatically, just as dramatically as school children are drawn away from their studies. This occurs as the two are saying their goodbyes and begin to make plans for their next meeting. It is saying that their desire to return to each other will be significantly powerful, at least according to Romeo.
What makes this a simile is the comparison between the longing for love, and the not longing for school. It also uses the word, ;as;.
My favorite simile quote from the play "Romeo and Juliet" by William Shakespeare is when the author has Romeo compare her to something richly-cloured, sparkling, pricelessly valuable and ornamental:
'like a rich jewel in an Ethiop's ear'
The whole image is richly exotic, and underlines the glamourous surroundings of the play's setting (when compared to muddy, grey smelly old Shakesperean London!) The italian city night-time scene is wonderfully evoked by the image Romeo paints in our minds of a warm, scented dark evening, with sweet music, torchlights, dancing and everyone in their prettiest coloured clothes. And the central star (for Romeo) is Juliet. We can imagine the size and priceless value of the glittering stone (it must be quite long to hang down from ear to cheek) and can also imagine the softness of Juliet's cheek, as well.
As I am sure that you know, a simile is when someone compares one thing to another and does so directly. So it is like when someone says "my love is like a red, red, rose." They are comparing their love to a rose and they are clearly doing so, using the word "like."
Romeo uses a simile in Act I, Scene 4 when he is talking to Mercutio. He compares love to a thorn. He says
Is love a tender thing? it is too rough,
Too rude, too boisterous, and it pricks like thorn.
Then, when he sees Juliet at the feast at her house, Romeo starts to talk about how beautiful she is. He uses another simile.
It seems she hangs upon the cheek of night
Like a rich jewel in an Ethiope's ear
Some similes from Romeo and Juliet include:
My bounty is as boundless as the sea,
My love as deep. (Act 2 Scene 2)
The brightness of her cheek would shame those stars
As daylight doth a lamp (Act 2 Scene 2)
Begot of nothing but vain fantasy
Which is as thin of a substance as the air (Act 1 Scene 4)
'So tedious is this day/As is the night before some festival.' Act 3 Scene 2 (Line 28-29)
"Juliet is the sun"
"But love from love, toward school with heavy looks"
"It is too rash, too unadvised, too sudden;/ Too like the lightning, which doth cease to be/ Ere one can say it lightens."
