The first time we know an actor worked was in 534 B.C. The changes in calendar between then and now make the year uncertain. This actor was called Thespis and he was Greek. The place where the play happened was called the "Theatre Dionysus" in Athens, and he won a competition. He was the first person to speak words as a character. This was a big change in storytelling. Before then, people sang and danced stories, but no one had been a person in the story. Today we call actors "thespians" because of Thespis.
