* "Beowulf" is a poem, not a person. It's a famous Old English epic poem telling the story of a hero named Beowulf.
* "Peon" isn't a relevant term here. "Peon" usually refers to a laborer, and has no connection to the poem Beowulf.
Here's what we can address about the poem Beowulf:
* Changes: Beowulf has been subject to changes over time, but not in the sense of being rewritten. The poem exists in a single manuscript, but even that has been subject to changes due to:
* Scribal errors: The original scribe making the copy could have made mistakes.
* Later additions: Some scholars believe there might be additions to the original poem by later scribes.
* Interpretations: How the poem is interpreted and translated also shapes our understanding of it.
* Why it changed: The changes mentioned above are primarily due to human error and the natural process of transmission of text through copying.
* When it was written down: The Beowulf manuscript is believed to have been written down around the 10th century AD, although the story itself likely predates that by several centuries.
In summary: The poem Beowulf was not "written down" as a complete piece until the 10th century, and there have been some minor changes in the text over time due to copying errors and possible later additions. However, the core narrative remains consistent and continues to be studied and enjoyed today.
