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.
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.
