What is often included in the scriptural narratives of an oratorio?

The correct choice focuses on historical events, which are a common feature in the scriptural narratives of an oratorio. An oratorio typically tells a story through music and includes a text that often draws on biblical stories or significant historical themes. These narratives are structured to convey moral or spiritual lessons and are usually told in a dramatic manner, much like an opera but performed without staging or costumes.

Understanding this context helps to appreciate how oratorios are designed to educate or inspire audiences about significant events or figures from history, often rooted in religious or cultural traditions. The focus on historical events distinguishes oratorios from other forms of music, as they emphasize storytelling through the lens of historical significance rather than character-driven drama or improvisational elements. This narrative approach is integral to the oratorio's ability to connect with audiences on a deeper emotional and intellectual level.
