Shakespeare's sonnets were composed between 1593 and 1601 but not published until 1609 in a collection of 154 poems addressing themes of love, beauty, and the inevitability of time. The sonnets are divided into two sections, with the first 126 addressing a young man and the final 26 addressing a "Dark Lady"; through their exploration of themes like decay and immortalization in poetry, the sonnets seek to preserve beauty beyond the constraints of mortality.
