The Cyclops gives Zeus thunder and lightning. They were given to Zeus as a gift for Zeus freeing the Cyclops.
He gave Zeus the thunderbolt, Hades the helmet of darkness and Poseidon the trident.
Zeus gave Apollo the power of the sun and poetry.
They expected to be given gifts...it was part of Ancient Greek culture to give gifts to your guests...I think.
Zeus
If I remember right, Odysseus insists that the men go in there so that the Cyclops would give them 'guest-gifts' .
No, Cyclops is not. Further, there were many "cyclops" in Greek myth.
From the Cyclops
According to Greek mythology, Zeus freed the cyclops from Tartarus and So, the cyclops felt grateful and started to help him create the weapons.
Prometheus stole fire from Zeus and gave it to mankind.
Polyphemus the Cyclops prayed to Poseidon rather than Zeus because Poseidon was the father of the cyclops.
Fearful.
