How might "Moctezuma II" have been different if the author chose to write the story of Moctezuma's imprisonment as a poem?

If the author chose to write the story of imprisonment of "Moctezuma II" as a poem, then it would have been a very long poem without a specific theme and specific flow

Explanation:

The story of Moctezuma II as written by the author explains each and every bit of the history. If he chose to write it as a poem, then, it would have been a very long poem and he might have also struggled to find a perfect theme for it as well.

The story specifically explains Moctezuma II's life as a ruler and his death. And, moreover there have been many accounts of story related to his death. An account by Cortés suggests that Moctezuma II was stabbed to death, while another written account says that he was stoned to death. Now, to write a poem, one also must possess the details right in order to have an appropriate ending and a theme that justifies the life of the ruler from the very beginning of the poem till the end. The ruler had a long life and many amusing events that would have caught the attention of many readers. So, it would have been impossible to write his story of reign and death in a single poem.
