Homer's The Odyssey has been popular for centuries, at one point it was used primarily to instruct students who were expected to learn Greek as part of their education, but nowadays, most young readers are introduced to this epic through their language arts curriculum.

You could say that this epic has become a curriculum staple for high school language arts classics, but that doesn't mean it should be.

Furthermore, the information on Greek and Roman gods would be far more relevant. When Language Arts teachers are limited with the amount of time they have to teach a subject, using a substantial amount of it teaching what is considered background information to a regular high school student, is an inefficient use of that time.
Where as in a classics curriculum, information about Greek and Roman gods would not be considered background information, rather the reason that the epic is read in class. Throughout The Odyssey gods intervene, almost constantly, with demonstrations of their powers. For example, one such goddess, Athena, goddess of wisdom, gives "girth and stature to the old field captain", when the situation calls for him to look impressive, and she is always ready to help.
