"Arguments for a Celtic cult of the severed head include the many sculptured representations of severed heads in La Tène carvings, and the surviving Celtic mythology, which is full of stories of the severed heads of heroes and the saints who carry their own severed heads, right down to "Sir Gawain and the Green Knight", where the Green Knight picks up his own severed head after Gawain has struck it off, just as St. Denis carried his head to the top of Montmartre.Physical evidence exists for the ritual importance of the severed head at the religious centre at Roquepertuse (southern France), destroyed by the Romans in 124 BC, where stone pillars with prominent niches for displaying severed heads were found.
