reading oedipus rex

i never thought that reading a play will be very much interesting until the moment i started reading Oedipus Rex by Sophocles. lots of question aroused in me when i read the play but i still tried to get the meaning or message that the dramatist tried to bring out in this play.

Oedipus Rex is a story of a king who was born with a curse that he will marry his own mother and have kids with her. he was also destined to kill his father and claim his throne of Thebes and the queen. Oedipus, without his knowledge, fulfills the oracle.

while reading this play, i had a very hard time in understanding the dialogues as it was constructed and re-written to fit 425 BC. i had to read the whole play two times in order to get the main idea of the play and i guess i have to read it again and again in order to understand the whole idea of the play is being given by the dramatist.

the questions that i keep on asking myself after reading the play are ; why Jocasta did not tell the truth to Oedipus after she realised the truth? how come Oedipus did not realise the truth when Jocasta talks about the curse her first son bore? how did Sophocles get the idea to have such an issue in his play? how did Oedipus get the idea that Creon is the one who killed King Laios, while Teiresias almost openly blamed him for the murder.

i am hoping to get to class and discuss the play there. i will be very much interested to know more about the play.
