A speaker pleads with her beloved, Phaon, demanding an explanation for his sudden coldness. She aches with the memory of a day they lay together on a shady bank, lost in whispered conversation and loving sighs, his eyes so captivating they seemed to dim the stars. That radiant warmth has vanished, replaced by rejection, and she can't understand why. Even as she confesses that her whole body is flooded with feeling—heated by his affection, frozen by his scorn—she finds no joy. The sonnet’s urgent, repeated question, “Why art thou chang’d?,” captures the bewilderment of someone whose passion meets only indifference. The mood is intimate and raw, balancing nostalgia for ecstasy against the sharp sting of loss. The closing line, wondering why rapture and pain are so close, leaves the reader with the ache of a love that thrives only in memory.
Sonnet XVIII: Why Art Thou Chang'd? — Summary
Why art thou chang'd? O Phaon! tell me why? Love flies reproach, when passion feels decay; Or, I would paint the raptures of that day, When, in sweet converse, mingling sigh with sigh, I mark'd the graceful languor of thine eye As on a shady bank entranc'd we lay: O! Eyes! whose beamy radiance stole away As stars fade trembling from the burning sky! Why art thou chang'd? dear source of all my woes! Though dark my bosom's tint, through ev'ry vein A ruby tide of purest lustre flows, Warm'd by thy love, or chill'd by thy disdain; And yet no bliss this sensate Being knows; Ah! why is rapture so allied to pain?
