"Odysseus can be characterized as courageous because he has the idea to use beeswax to protect his crew from the Sirens’ song."
This statement highlights not only Odysseus's bravery but also his cleverness and foresight in protecting his men from a significant danger. It reflects his proactive approach to leadership and his willingness to take initiative in perilous situations, showcasing his courage in a way that emphasizes both mental and physical strength.
