teiresias

i have always been fond of greek mythology for it's wide range of characters. it is somewhat fascinating to learn about the different Gods and their roles, though i have to say i never really heard of Teiresias. as i read Oedipus Rex, i never really expected the characters to be based on the greek mythology. as i searched the web on Teiresias, i was surprised to find out that Cadmus really existed and it was just not a name i stumbled on in Oedipus Rex. Tales about Teiresias seem to vary but i really like the one about Hera cursing him to be a woman for 7 years just because he disturbed mating snakes. but about him being blind, i am really not sure as he being cursed by Athena for watching her bathe and Hera cursed him for agreeing with Zeus seem to relevant and his foresight was given by Zeus as well as his ability of augury seem consistent. which one could it be? i have no idea but i really like his tale and i think that it tallies with his role in Oedipus Rex as a blind seer who has visions but tries his best not to reveal them. Teiresias must have been cursed really badly,i mean seven generations is a really long time even if you are physically blind.
