Answer:
It is ironic that Teiresias is characterized as a "great seer" because he is blind.
Explanation:
Teiresias is a prophet that became blind after he saw the goddess Athena bathing and she took his eyes as a punishment. Ironically, he is a great seer not because he has a great sight, but because Athena gave him foresight, turning him into an oracle. Teiresias can see the future and prophetized Oedipus demise.
