What are examples of cosmic irony in Oedipus Rex?
Oedipus's downfall is directly related to his inability to comprehend the role of fate in mortals's lives and how it is manipulated by the gods for their own ends. Oedipus acts as if he can defy fate, even after he's been explicitly warned of the consequences of his actions by the blind seer, Tiresias. Of course, he can't outsmart fate, and the end result of his stubborn defiance is the exact opposite of what he'd expected; this is what makes it ironic. Every step that Oedipus takes to try to avoid his fate—such as attempting to get to the bottom of how his father was killed—only brings him nearer to his eventual doom.
