Here's why it's difficult to know:
* Limited historical records: While there are some accounts of Cortés's life, they primarily focus on his military campaigns and conquests. There's little information about his personal interests or reading habits.
* Literacy in the 16th century: Literacy was not widespread during Cortés's time. It's possible he could read, but even if he did, he might not have had access to a large library or collection of books.
* Focus on action: Cortés was a man of action, known for his ambition and ruthlessness in conquering the Aztecs. It's unlikely he would have spent much time reading for pleasure.
While we can't definitively say what book Cortés might have enjoyed, we can speculate based on his background and the era in which he lived. He might have been interested in books about:
* Military strategy: As a soldier, he likely would have appreciated works on military tactics and leadership.
* Religion: Cortés was a devout Catholic, so he might have read religious texts.
* Exploration and travel: Given his own adventures, he could have enjoyed books about past voyages and discoveries.
Ultimately, the question of Cortés's favorite book remains unanswered.
