One of the things I love about the Iliad and the Odyssey is that I always notice new things when I re-read them.
During my last read-through, the importance of baths in both Homeric works stuck out to me.
In Homer, the bath serves as a ritual in several ways. In both the Iliad and the Odyssey, warriors returning from the battlefield take baths to wash the gore and grime of battle off themselves physically and spiritually. In this instance, the bath serves as a purification ritual.
