as previously mentioned, Tiresias lived life both as a man initially, but he was transformed into a women for several years. He makes appearances in many Greek legends and stories, but the one that stands out to many is his role in Oedipus the King. He speaks truths that people often don't want to know (like when Oedipus asks who killed Laius). His prophesies always come true through the actions of others (even as they try to prevent it). Even in the afterlife, he advises Odysseus, which is what is alluded to in the following line: "bring the sailor home from sea." Tiresias experiences a doubleness which allows him to see more.
