So when Cerwyn Jones found himself being punished by a court for carrying a five-inch ceremonial knife in a pub he was quick to plead special Wiccan circumstances.
The 52-year-old was sentenced to four months of staying indoors between the hours of 7pm and 7am.
But magistrates agreed to suspend the order on four nights after hearing he needed to go out during a full moon to practise his Wicca faith.
Wicca – or white witchcraft – is a neo-pagan religion which saw a resurgence in popularity in the 20th century.
Its followers believe the whole cosmos is alive and as such the waxing, waning and full moon are extremely important.
