Religio Romana is the religion that probably about 1/5 to 1/4 of Martians subscribe to. It is, simply described, a polytheistic pantheon hearkening back to the days of Rome, much like many other aspects of Martian culture; gods such as Jupiter, Mars, Juno, Janus etc.. are worshiped. Since it is non-dogmatic, there are many different beliefs contained under this particular name, and the religion itself is very ritualistic, having specific formulae for such things as sacrifice and festivals. It has of course been updated to be more 'current' with the modern age while retaining its classical flavour and charm. Mars's capital Hesperia and the city of Hellas are considered the two places with the highest proportion of Religio practitioners.
