For one, it shows that Roman polytheists do not celebrate every single ancient Roman holiday; at least not all of us. The question popped up again several days ago at the Cultus Deorum group on Facebook and it’s good to keep in mind that the communal emphasis is on monthly occasions, such as the Ides, and a few major yearly festivals like Saturnalia. The rest comes down to personal preference and family traditions – the sacra privata or private religion.
The calendar section also serves the purpose of demonstrating that, unlike what too many people still think, the wiccan eightfold wheel of the year is not universal among polytheists. In reality, many of us celebrare a lot more dates and there’s not even an exclusive focus on the seasons or rhythms of the Earth, as some of festivals go back to the anniversaries of both people and temples.
Finally, it is intended to show a third thing: polytheism doesn’t have to be xenophobic or culturally pure. The opposite is actually the norm, for as people trade, move and interact, so do their gods. It happened in the past and there is no reason why it shouldn’t happen today. Not to mention that polytheism, by accepting the existence of a multitude of deities, can also be an open system whereby gods of different cultural origins can and indeed will be worshiped by the same people. Conor has recently talked about it. In that spirit, my fasti or list of religious festivities includes celebrations dedicated not just to Roman, but also Norse and Egyptian deities.
On a final note, it should be noted that a calendar is a changeable thing. Dates are added and dates are dropped as things evolve. There are already a few differences between what’s in the calendar section and what I wrote in the series of posts. One of those changes is the addition of a festivity to the Iberian goddess Nabia on March 9th. It’s still an experimental thing, born out of my desire to connect with local gods from my home town. A Nabia Alcobacensis is a possibility that I’m delving into, but only time will tell if I’m onto something or not.
