Why is the authorship of Prometheus Bound debated by scholars?

While Prometheus Bound is traditionally attributed to the Greek dramatist Aeschylus, its authorship remains a subject of scholarly debate.12

The uncertainty stems primarily from the play's unique characteristics and the lack of a definitive date for its composition. Scholars have noted that the play's depiction of Zeus as a tyrant is particularly striking and controversial, leading some to question whether the style and thematic treatment align with the known works of Aeschylus. Although many experts continue to regard the tragedy as a product of the playwright's final years, the absence of conclusive evidence regarding its origin ensures that the question of its authorship persists in academic discourse.12
