Who was known for his tragic mistake of forgetting to change sails?

Theseus is the figure known for the tragic mistake of forgetting to change the sails. In Greek mythology, after slaying the Minotaur in the labyrinth of Crete, Theseus was supposed to signal to his father, Aegeus, on the journey back to Athens. He had promised to change his ship's sails from black to white as a sign of his safe return. However, he forgot to change the sails, leading Aegeus to believe that Theseus had died. In his despair, Aegeus threw himself into the sea, which gave its name to the Aegean Sea.

This event highlights the themes of miscommunication and the tragic consequences that can arise from a single oversight. Theseus's mistake not only affected his life but also had dire implications for his father's fate. This story serves as a poignant reminder of the importance of promises and the impact of our actions on others.
