I just posted a question over in the Mythology SE and used this sentence:
I'm tagging Greek and Roman mythology, but open to other mythologies as well.
I wanted to say:
I'm tagging Greek and Roman mythology, but open to other ____ of mythology as well.
I couldn't think of the proper word to go in the blank. 'Branches' didn't seem to fit because the different world mythologies don't really branch from each other. 'Types' didn't feel right either--there really aren't types of mythology. Same problem with 'varieties' and 'variations'.
What word would fit in that blank?
