Why does the author have polyphemus stop the large ram Odysseus hides under ant talk to the sheep?

In Homer's "Odyssey," Polyphemus stops the ram that Odysseus is hiding under to question it, which emphasizes the Cyclops' ignorance and arrogance. This moment showcases his inability to see beyond his immediate surroundings and highlights Odysseus' cleverness in using the ram as a cover for his escape. The interaction also serves to build tension, as the audience anxiously anticipates whether Polyphemus will discover Odysseus’ ruse. Ultimately, it underscores the themes of cunning versus brute strength within the narrative.
