If you know any sources in which I can research Celtiberian pre-Christian religion, please share them with me.
For context, I've discovered that a large portion of my ancestors originate from central, north and western Iberia. DNA test points me to be mostly of Celtiberian/Cantabrian admixture.
I seek to better understand my ancestors so I can possibly emulate their religion and see where syncretism could work with my other ethnic ancestorial religions
