>> In a poem of Taliessin, translated by Davies, in his Appendix No. 6, is the following enumeration of a Druid's titles:---
"I am a Druid; I am an architect; I am a prophet; I am a serpent" (Gnadr).From the word "Gnadr" is derived "adder," the name of a species of snake. Gnadr was probably pronounced like "adder" with a nasal aspirate.<< Ref 2
