Everyone knows this but what a lot of people don’t is that these two epics share many of the same concepts. Such as the nostro (the Greek term for homecoming), xenis (guest/host relationship), oikos (household), and aganoriss (recognition). In both epics these themes are illustrated.
In The Odyssey the theme of nostro is very prevalent in this epic. Basically the whole story is based around this concept. The main character, Odysseus’ whole goal in the book is his homecoming. Along his journey he faces many challenges separating him from his home (Ithaca) and his family. The main thing that keeps Odysseus going is the thought of one day being home with his family, no matter how many setbacks he faces.
In The Epic of Gilgamesh the theme of nostro is more or less established - the only difference between the two epics is nostro is not the main focus in this one. The main character in this epic is the great and powerful King Gilgamesh. Gilgamesh is not affected by the theme of homecoming until the end of the book, after his best friend Enkidu is killed by the Bull of Heaven and he goes looking for eternal life.
