What did Ariadne give Theseus and why?

Ariadne gave Theseus a ball of thread, often referred to as "Ariadne's thread," to help him navigate the labyrinth and find his way out after he killed the Minotaur. This clever gift allowed him to trace his path back, ensuring he wouldn't get lost in the intricate maze. Her assistance was crucial for Theseus's successful escape, and it symbolized her love and loyalty to him. Ultimately, Ariadne's gift enabled the hero to conquer the monster and return safely.
