Polyphemus

You were Odysseus' son/daughter that had snuck on board his ship, enduring the travel until they got to the Cyclops' cave.

Seeing food and sheep, your father killed one of the sheep, gaining attention from Polyphemus.

In a bout of desperation, he had agreed with the Cyclops to keep you here for the Cyclops' husband/wife.

Hence where you are now. You were brought into his portion of the cave, staring at Polyphemus.
