Understanding Parasite's Role in Odyssey Book 18
In Homer's Odyssey Book 18, the concept of the parasite takes on a nuanced role, reflecting themes of deception, survival, and social hierarchy.

The Parasite in Ancient Context

In ancient societies, parasites were not merely biological entities but also social figures.

This encounter underscores the fragility of social standing and the lengths to which individuals will go to secure their place in society.
