In William Shakespeare's "Romeo and Juliet," the line "One fairer than my love? The all-seeing sun ne'er saw her match since first the world begun" expresses Romeo's deep admiration and passion for Juliet. He believes that no one in the world is as beautiful or extraordinary as she is. This declaration emphasizes the intensity of his feelings and sets the tone for their tragic love story.

Shakespeare uses vivid imagery to convey Romeo’s perception of beauty, suggesting that even the sun, which sees everything, has never witnessed anyone as enchanting as Juliet. This moment underscores the theme of idealized love throughout the play, illustrating how love can elevate one person above all others in the eyes of a lover.
