olympian, adj.  relating to a mountain in thessaly, once inhabited by
gods, now a repository of yellowing newspapers, beer bottles and
mutilated sardine cans, attesting the presence of the tourist and his
appetite.

    his name the smirking tourist scrawls
    upon minerva's temple walls,
    where thundered once olympian zeus,
    and marks his appetite's abuse.
