In the Odyssey, Melantho is a foil to Eurynome and Eurykleia.
Melantho, the sibling of Melanthios, is a palace servant who is loyal to the suitors rather than the Queen. In order to die in the most humiliating way, she is hanged.
In literature, a foil character is a character that is opposite to the main character in personality, physical appearance, or both.
