Step 1: Concept Identification: The query requires identifying the earliest among the three major Athenian tragedians whose plays have been preserved.
Step 2: Detailed Analysis: The 5th century BCE, considered the golden age of Greek tragedy, features three principal playwrights. Their chronological sequence is as follows:
1. Aeschylus (circa 525 – circa 456 BCE): Recognized as the progenitor of tragedy, he is the earliest of the three. His innovations include the introduction of a second actor, enabling dialogue distinct from the chorus.
2. Sophocles (circa 497 – circa 406 BCE): Succeeding Aeschylus, he is credited with incorporating a third actor and enhancing character depth.
3. Euripides (circa 480 – circa 406 BCE): The final prominent tragedian, noted for his psychological depth and critical examination of societal norms.
Aristophanes was a playwright of comedy, not tragedy.
Step 3: Conclusion: Aeschylus is acknowledged as the foremost of the great Greek tragedians.
