What allowed oratorios to become popular?

The popularity of oratorios can be attributed significantly to the success of opera. As opera gained traction as an influential art form in the late Renaissance and Baroque periods, it fostered a broader appreciation for musical drama and storytelling. This cultural shift led to a growing audience that was receptive to other similarly structured musical genres, such as oratorios.

Oratorios emerged as compelling alternatives to operas, often featuring religious themes and narratives without the theatrical staging associated with opera. They could be performed in church settings or concert halls, allowing them to reach audiences beyond the confines of theatrical productions. The rise of oratorios was thus closely aligned with the established prominence of opera, as the public's newfound appreciation for dramatic composition and vocal performance created an environment where oratorios could thrive.

While factors such as increased public interest, government support, and religious endorsements all played roles in the broader context of the arts during this time, the direct influence of opera's success was a significant driving force behind the rise of oratorios.
