Thespis was an Ancient Greek poet. He was born in the ancient city of Icarius (present-day Dionysos, Greece). According to certain Ancient Greek sources and especially Aristotle, he was the first person ever to appear on stage as an actor playing a character in a play (instead of speaking as himself). In other sources, he is said to have introduced the first principal actor in addition to the chorus. He is often called the "Inventor of Tragedy". Wikipedia
