The texts on curse tablets are typically addressed to infernal or liminal gods such as Hermes, Charon, Hecate, and Persephone. Sometimes, a sometimes a dead person (probably the corpse in whose grave the tablet was placed) had to mediate. Some texts do not invoke the gods, but merely list the targets of the curse, the crimes or conditions when the curse is valid, and/or the intended ill to befall them. Some tablets are inscribed with nothing more than the names of the targets. Some people think that an oral spell may have accompanied the making of the curse.
