Shakespeare’s speaker adores a young man, yet an anxious urgency runs through these lines. He wishes the beloved could simply be “your self” forever, but the beauty he carries is only borrowed — a “lease” that will expire. To outrun death, the speaker insists, that sweet form must be passed on through a child, a “sweet issue” who would wear the beloved’s face and make him “Yourself again” after death. The voice is intimate and tender, but edged with fear. Images of a proud house crumbling under winter storms and the “barren rage of death’s eternal cold” make loss feel physical and stark. Then the final couplet lands like a quiet, personal nudge: “you had a father: let your son say so.” The beloved exists because someone once chose to create life; now he must do the same. The mood hovers between loving persuasion and the chill of time slipping away.
Sonnet 13: O! that you were your self; but, love you are — Summary
O! that you were your self; but, love you are No longer yours, than you your self here live: Against this coming end you should prepare, And your sweet semblance to some other give: So should that beauty which you hold in lease Find no determination; then you were Yourself again, after yourself's decease, When your sweet issue your sweet form should bear. Who lets so fair a house fall to decay, Which husbandry in honour might uphold, Against the stormy gusts of winter's day And barren rage of death's eternal cold? O! none but unthrifts. Dear my love, you know, You had a father: let your son say so.
