This document provides a detailed summary and analysis of Shakespeare's sonnets. It discusses how the sonnets can be divided into two sections - sonnets 1-126 addressing a male friend, and sonnets 127-152 addressing a "dark mistress." The main themes are constancy versus inconstancy between the two subjects of the sonnets, and how Shakespeare uses them to represent non-physical and physical realities. The document analyzes metaphor usage and how Shakespeare portrays the two subjects in relation to themes of youth, beauty, fidelity and the test of time.
