Analysis of Major Characters

Romeo

The name Romeo, in popular culture, has become nearly synonymous with “lover.” Romeo, in Romeo and Juliet, does indeed experience a love of such purity and passion that he kills himself when he believes that the object of his love, Juliet, has died. The power of Romeo’s love, however, often obscures a clear vision of Romeo’s character, which is far more complex.

Even Romeo’s relation to love is not so simple. At the beginning of the play, Romeo pines for Rosaline, proclaiming her the paragon of women and despairing at her indifference toward him. Taken together, Romeo’s Rosaline-induced histrionics seem rather juvenile. Romeo is a great reader of love poetry, and the portrayal of his love for Rosaline suggests he is trying to re-create the feelings that he has read about. After first kissing Juliet, she tells him “you kiss by th’ book,” meaning that he kisses according to the rules, and implying that while proficient, his kissing lacks originality (1.5.107). In reference to Rosaline, it seems, Romeo loves by the book. Rosaline, of course, slips from Romeo’s mind at first sight of Juliet. But Juliet is no mere replacement. The love she shares with Romeo is far deeper, more authentic and unique than the clichéd puppy love Romeo felt for Rosaline. Romeo’s love matures over the course of the play from the shallow desire to be in love to a profound and intense passion. One must ascribe Romeo’s development at least in part to Juliet. Her level-headed observations, such as the one about Romeo’s kissing, seem just the thing to snap Romeo from his superficial idea of love and to inspire him to begin to speak some of the most beautiful and intense love poetry ever written.

Yet Romeo’s deep capacity for love is merely a part of his larger capacity for intense feeling of all kinds. Put another way, it is possible to describe Romeo as lacking the capacity for moderation. Love compels him to sneak into the garden of his enemy’s daughter, risking death simply to catch a glimpse of her. Anger compels him to kill his wife’s cousin in a reckless duel to avenge the death of his friend. Despair compels him to suicide upon hearing of Juliet’s death. Such extreme behavior dominates Romeo’s character throughout the play and contributes to the ultimate tragedy that befalls the lovers. Had Romeo restrained himself from killing Tybalt, or waited even one day before killing himself after hearing the news of Juliet’s death, matters might have ended happily. Of course, though, had Romeo not had such depths of feeling, the love he shared with Juliet would never have existed in the first place.

Among his friends, especially while bantering with Mercutio, Romeo shows glimpses of his social persona. He is intelligent, quick-witted, fond of verbal jousting (particularly about sex), loyal, and unafraid of danger.

Juliet

Having not quite reached her fourteenth birthday, Juliet is of an age that stands on the border between immaturity and maturity. At the play’s beginning however she seems merely an obedient, sheltered, naïve child. Though many girls her age—including her mother—get married, Juliet has not given the subject any thought. When Lady Capulet mentions Paris’s interest in marrying Juliet, Juliet dutifully responds that she will try to see if she can love him, a response that seems childish in its obedience and in its immature conception of love. Juliet seems to have no friends her own age, and she is not comfortable talking about sex (as seen in her discomfort when the Nurse goes on and on about a sexual joke at Juliet’s expense in Act 1, scene 3).

Juliet gives glimpses of her determination, strength, and sober-mindedness, in her earliest scenes, and offers a preview of the woman she will become during the four-day span of Romeo and Juliet. While Lady Capulet proves unable to quiet the Nurse, Juliet succeeds with one word (also in Act 1, scene 3). In addition, even in Juliet’s dutiful acquiescence to try to love Paris, there is some seed of steely determination. Juliet promises to consider Paris as a possible husband to the precise degree her mother desires. While an outward show of obedience, such a statement can also be read as a refusal through passivity. Juliet will accede to her mother’s wishes, but she will not go out of her way to fall in love with Paris.

Juliet’s first meeting with Romeo propels her full-force toward adulthood. Though profoundly in love with him, Juliet is able to see and criticize Romeo’s rash decisions and his tendency to romanticize things. After Romeo kills Tybalt and is banished, Juliet does not follow him blindly. She makes a logical and heartfelt decision that her loyalty and love for Romeo must be her guiding priorities. Essentially, Juliet cuts herself loose from her prior social moorings—her nurse, her parents, and her social position in Verona—in order to try to reunite with Romeo. When she wakes in the tomb to find Romeo dead, she does not kill herself out of feminine weakness, but rather out of an intensity of love, just as Romeo did. Juliet’s suicide actually requires more nerve than Romeo’s: while he swallows poison, she stabs herself through the heart with a dagger.

Juliet’s development from a wide-eyed girl into a self-assured, loyal, and capable woman is one of Shakespeare’s early triumphs of characterization. It also marks one of his most confident and rounded treatments of a female character.

Friar Lawrence

Friar Lawrence occupies a strange position in Romeo and Juliet. He is a kindhearted cleric who helps Romeo and Juliet throughout the play. He performs their marriage and gives generally good advice, especially in regard to the need for moderation. He is the sole figure of religion in the play. But Friar Lawrence is also the most scheming and political of characters in the play: he marries Romeo and Juliet as part of a plan to end the civil strife in Verona; he spirits Romeo into Juliet’s room and then out of Verona; he devises the plan to reunite Romeo and Juliet through the deceptive ruse of a sleeping potion that seems to arise from almost mystic knowledge. This mystical knowledge seems out of place for a Catholic friar; why does he have such knowledge, and what could such knowledge mean? The answers are not clear. In addition, though Friar Lawrence’s plans all seem well conceived and well intentioned, they serve as the main mechanisms through which the fated tragedy of the play occurs. Readers should recognize that the Friar is not only subject to the fate that dominates the play—in many ways he brings that fate about.

Mercutio

With a lightning-quick wit and a clever mind, Mercutio is a scene stealer and one of the most memorable characters in all of Shakespeare’s works. Though he constantly puns, jokes, and teases—sometimes in fun, sometimes with bitterness—Mercutio is not a mere jester or prankster. With his wild words, Mercutio punctures the romantic sentiments and blind self-love that exist within the play. He mocks Romeos self-indulgence just as he ridicules Tybalt’s hauteur and adherence to fashion. The critic Stephen Greenblatt describes Mercutio as a force within the play that functions to deflate the possibility of romantic love and the power of tragic fate. Unlike the other characters who blame their deaths on fate, Mercutio dies cursing all Montagues and Capulets. Mercutio believes that specific people are responsible for his death rather than some external impersonal force.
