tabella defixionis (12. 386)

Popular and widely employed during Greco-Roman times well into the Christian era, curse tablets (κατάδεσμος—a binding spell) were often discretely or surreptitiously buried with the dead to settle a grudge with surviving competitors over business and romantic affairs and even among rival sports teams as a way to petition the chthonic gods or place spirits to compel malediction for the after life. Like the cache of twenty-two curses recently discovered in an ancient cemetery near Orleans, the most common media was thin lead scrolls as due to their malleability could be easily inscribed and were also an element associated with the underworld deities. What makes this particular discover unique is that one grave contained a curse written in Gaulish, the vulgar language of the region in common parlance (though really preserved in written form) for centuries after the Roman conquest. Because of the paucity of documentation for Gallo-Roman translating is a challenge but there is a another class of curse tablets called Voces mysticae (vox magica) which do not seem to be rendered in any known language and are a secret invocation that only demons can decipher—with scholars teasing out palindromes (previously here and here) and boustrophedon.
