Shakespeare’s “Sonnet 106” is one of the many sonnets he wrote about a “fair youth”—a certain young man who had quite captivated Shakespeare’s affections. In the sonnet, he addresses the unnamed youth while also addressing the concept of youth itself, personifying it while saying that this man embodied the concept perfectly.
It is unclear exactly about whom Shakespeare is speaking in these sonnets, but there are quite a few of them. Of the theories about the intended recipient of the sonnet, the most likely individual is a young man named Henry Wriothesley, the Earl of Southampton, who was known to spend a lot of time with Shakespeare. Regardless of who the “fair youth” was, he was clearly very close to Shakespeare and was held in high regard.
