Music goes back to our beginnings as various finds of 40,000 year old flutes show. Music and healing are often paired and music was sometimes used as a form of healing. Many of the Gaulish deities mixed and matched roles, attributes and even names with other cultures. The ancient Celts traveled so far they couldn’t help but run into other Gods and see similarities to their own. Meanwhile, the Romans were quite prone to creating Roman names for local deities and pairing them up with a Roman God, just to make everything seem Roman to them. All this makes it quite likely that there was a local deity connected to healing or music or both who was simply renamed.
Ianuaria’s roots are long gone but close your eyes and listen for the sound of flute music drifting over the hills on a chilly day and you just might catch glimpse of where she went.
