What are some college majors/jobs that involve learning ancient cultures, languages, and religion?

Seems to me like your interests are very academic in nature. Most of the things you listed could be studied in one way or another by majoring in History with a specific concentration in ancient/nordic culture or clic civilizations. Be careful though, getting a job in such a field requires advanced degrees and years of research. Most of the time you will need a Phd in order to be able to directly work, and make a living of, such material. Museums are a good option if you want a more professional and less academic route. They only require a masters degree in Museum Studies or History/Art History, depending on what kind of institution they are. The work will be less hands-on with regards to the material you listed and will be more administrative in nature however.
