Excellent. The movie “Excalibur” is my only other reference for the charm.
It was created for the movie. As far as I know it has no real historical connotation.
The translation is: “Serpent’s breath, charm of death and life, thy omen of making.” from http://dandalf.com/charm.html Really its an interesting look at the origins of the language the filmmaker used.
Ah... I love that movie, I am gonna have to go dig it out of the CD archive (cardboard box in garage LOL).
