what is in the contex in the first pharagraph in antigone

This really depends on what version of the story you have. Generally, we see the meeting of two sisters. Antigone and Ismene are the sisters of the dead brothers, and they are now the last children of the ill-fated Oedipus. In the opening of the play, Antigone brings Ismene outside the city gates late at night for a secret meeting: Antigone wants to bury Polyneices' body, in defiance of Creon's edict. Ismene refuses to help her, fearing the death penalty, but she is unable to dissuade Antigone from going to do the deed by herself.
