patroclus 

Esau (from the Bible's Book of Genesis) and Patroclus (from Homer's Iliad) are from entirely different literary and cultural traditions, but they share a prominent thematic parallel: both are the shadowed, loyal second-in-command figures who meet a tragic fate that alters the path of the primary protagonist. [1, 2, 3]


Specific parallels between the two figures include:

While Esau is the disinherited twin dealing with the fallout of a sibling rivalry, and Patroclus is the devoted friend dealing with a fated destiny in the Trojan War, both function as the tragic "other half" to the main patriarch or hero. [14, 15, 16]
