How are prose and verse combined in early Irish epics?

In early Irish epics, such as those found in the Ulster cycle, the narrative is primarily composed of prose, with verse passages interspersed throughout the text.12

These verse sections typically serve specific functions within the storytelling:
* Dialogue: Verse is frequently used for exchanges between characters.3
* Heightened Emotion: Poetic passages are employed to convey intense feelings or dramatic moments.2
* Description: Verse is used to provide descriptive detail within the narrative.2

Because these verse sections are often older than the surrounding prose, scholars suggest that these stories may have evolved from an earlier, lost body of heroic poetry. This structure of combining prose narrative with non-narrative poetic passages is a characteristic feature of early Irish heroic literature, showing a resemblance to traditions found in early Sanskrit literature.13
