What is the theme of a Elizabethan sonnet?

Elizabethan sonnets typically explore themes of love, beauty, and mortality. They often express the poet's admiration for a beautiful young man or woman, and they may also lament the passage of time and the inevitability of death. Other common themes in Elizabethan sonnets include the power of poetry to immortalize the beloved and the conflict between the poet's desire for the beloved and his or her sense of duty or obligation.
