Mythology, a highly relevant topic in most aspects, if not all.
Thomas C. Foster gives a few examples of literature influenced by mythology, such as Percy Jackson and The Olympians by Rick Riordan, The Iliad, Daedalus and Icarus, and a few more. He even talks about how there were school teams in his state named after Romulus, Remus, Rome, The Spartans, The Trojans, and more. All of those influenced by a story that was influenced by mythology.
Mythology from every religion has affected the world to this very day. We have towns and cities named from mythology. Athens, for example, was named after Athena; the Greek goddess of war, handicraft, and practical reason. High school students read books based off of mythology, mainly Greek or Roman mythology. We have fantasy series based off of mythology, think Magnus Chase and the Gods of Asgard, or The Kane Chronicles both by Rick Riordan.
