In Gallo-Roman religion, Smertrios or Smertrius was a god worshipped in Gaul and Noricum.
Smertrius is one of the Gaulish gods depicted on the Pillar of the Boatmen, discovered in Paris.
Here is depicted as a well-muscled bearded man confronting a snake which rears up in front of him.
The god brandishes an object which has usually been interpreted as a club but which rather resembles a torch or firebrand.
The normal interpretation of the god's attribute as a club has led to the identification, by modern scholars, of Smertrius and Hercules.
