In Creon's metaphor about safety, what does he liken safety to?

In Creon's metaphor about safety, he likens safety to a ship. This metaphor illustrates the idea that safety is something that can be navigated and requires skill and experience to manage properly, much like sailing a ship. Just as a ship must be steered carefully through waters that may be unpredictable and turbulent, Creon suggests that safety in governance and statecraft must be actively maintained and navigated to avoid potential dangers or disasters. The imagery of a ship emphasizes the need for vigilance and adaptability in leadership, making it a fitting analogy in the context of his character's struggles and decisions throughout the play. This metaphor highlights Creon's belief in the necessity of strong leadership and control to ensure the stability and safety of Thebes.
