Here's why:
* Subject: "You" is the subject of the sentence.
* Verb: "Know" is the verb, indicating a state of being familiar with someone.
* Object: "Him" is the object of the verb "know".
* Prepositional Phrase: "Through his works" is a prepositional phrase that clarifies how you know him.
However, there might be a slight nuance depending on the context. If you're referring to someone's artistic works, "You know about him through his works" might be a more precise expression. This makes it clear that you know about the person because of their creations, not through personal interaction.
