From the non-word arthame from a French manuscript. Arthame is either from a misreading of handwritten Italianarctrave, which is a variant of architrave(“main beam”), or from corruptions of the the Medieval Latin word artavus(“quill-sharpening knife”). Artavus was also mistranslated into the non-word artauo in an Italian manuscript. The arthame was conflated with the cortel nero ("black knife") by the author Grillot de Givry in 1931, and that conflation was passed on to Gerald Gardner (the creator of Wicca).
