I know! I read Greek, and even occasionally understand it. The word I would
have used, if I had thought it was commonly known, is "ephemeral". Something
which comes and then passes again. This describes the temporary nature of
a comic book, whereas a 'periodical' indeed suggests something which repeats
over and over and over...

December 5.th is a periodical occurrence, but yesterday will never be back.
