prayed to zeus
Polyphemus the Cyclops prayed to Poseidon rather than Zeus because Poseidon was the father of the cyclops.
He prayed to Athena
The Cyclops prays to Poseidon, the god of the sea, when he asks that Odysseus lose all his men and have a rough journey home. Poseidon holds a grudge against Odysseus for blinding the Cyclops, who is his son.
Polyphemus blames his death on "Nobody" and his friends. "Nobody" is what Odysseus tells him his name is. When Polyphemus tells his friend that Nobody is killing him they don't believe him. They take it as no one is killing him. They say Poseidon (their father) has sent the plague to him. His friends tell him to pray to their father!
To be correct what did Odyessus do to the cyclops. He poked the cyclops in the eye.

cyclops
1. When the Cyclops Polyphemus asks Odysseus where his ship is, Odysseus lies and says it was destroyed upon the rocks of the shore. 2. Odysseus told the cyclops that his name was "Nobody". When Odysseus and his men blind the cyclops (neither Odysseus nor the Cyclops dies), he yells to his friends for help. They ask him what is wrong and he answers saying, "Nobody's killing me now by fraud and not by force!" (Fagles' translation 9.455). They respond by saying that it must be the plague killing him and they can't help. They advise him to pray.
