In Greek Mythology, Tiresias (also transliterated as Teiresias) was the most famous soothsayer of Greece, was born at Thebes. He was the son of Eueres and Chariclo, and the descendant of Udaeus of Sparti. He was blinded for his seventh year but lived up to a very old age. There were many versions of stories and beliefs to how Teiresias was blinded.
Firstly, Teiresias was believed to be born with the gift of foretelling. The gods feared that Teiresias would see too much that the gods wished to keep conceal. So the gods took his eyesight, depriving the soothsayer of physical vision.
Secondly, according to the poem Bath of Pallas by Callimachus, Teiresias was believed to have been blinded by Goddess Athene because Teiresias saw her bathing. She could not remove her curse so she in return gave Teiresias a seven generation long life, the power to understand the voices of the birds, and gave him a staff, with the help of which he could walk as safely as if he had his eyesight.
Thirdly, Teiresias was believed to be blinded by Hera because Teiresias did not side on her but on Zeus. The issue was that whether male had the most pleasure in sex or a female. As Teiresias had both the experience of being a male and female, so he was questioned. Teiresias agreed that female had the most pleasure and it was believed to have offended Hera and so Teiresias was blinded but given the gift of seven long generation of life.
Teiresias had a daughter named Manto, who was also a gifted seeress.
Teiresias died after he was struck by an arrow of Apollo after he drank the water from the spring Tilphussa.
