“ TEIRESIAS, in Greek legend, a famous Theban seer, son of Eueres and Chariclo. He was a descendant of Udaeus, one of the men who had sprung up from the serpent’s teeth sown by Cadmus. He was blind from his seventh year, for which various causes were alleged. Some said that the gods had blinded him because he had revealed to men what they ought not to know. ”
