Why did tiresias get summoned?

Tiresias, the blind prophet of Thebes, was summoned primarily for his wisdom and insight into the future. In Greek mythology, he was often called upon to provide guidance in times of crisis, particularly when characters faced moral dilemmas or needed clarity about their destinies. In works like Sophocles' "Oedipus Rex," he is summoned to reveal the truth about Oedipus's fate and the plague afflicting Thebes. His unique ability to see beyond the physical world made him a crucial figure in understanding the complexities of human actions and their consequences.
