Ancient Greek tragedies were often performed in trilogies, which were three plays that were related in some way. The first two plays of the trilogy would typically set up the conflict, and the third play would resolve it. This structure allowed Sophocles to explore a wide range of themes and characters in depth.
As a Trilogy
In addition to writing trilogies, Sophocles also wrote many individual plays. These plays were often inspired by Greek mythology, but he also wrote about contemporary issues. Sophocles' plays were known for their realism, their exploration of human nature, and their beautiful language.
By writing at and as a trilogy, Sophocles was able to create some of the most powerful and enduring works of literature in the Western tradition. His plays continue to be performed and enjoyed by audiences around the world.
