Bad Celts! No Wolf
God for you! Try the Germans or the Lithuanians or the Samoyed or the Comanche, maybe. The Celts mostly were stuck with the second string, like the Kale God or the Divine Digger of Ditches.
Cailean, however, appears to have been a water deity in ancient Gaul. A finely-carved statue of Cailean (depicted as a male figure with long flowing hair) and votive offerings were found in a former sacred spring outside Caiteau, near the headwaters of the River
The "Caiteau Cailean" is one of the outstanding pre-Roman Celtic finds of this century.
