I have already written an article about this subject but I want to expand and share another spell from PGM VII 429-458 In that spell Osiris is called with voces magicae implying their secret names. The interesting thing is that the spell is short and quick but it also requires knot magick if you release the katadesmos in special places, using again the famous voces magicaes ASKEI KAI TASKEI (as the ancient text writes).
This binding spell is very powerful as the ancient text intones. It can cause illness, make enemies, destroy and alter a situation, so use it to promote good magick according to the wiccan rede. Take a lead tablet from a water pipe of cold water. Write with a headless needle made of bronze:
Katadesmoi in plural, katadesmos in singular are an ancient hellenic magickal technique. It requires a lead tablet and a nail. The desired purpose is simply written in the lead and then it is fold in half and with a nail on the center it is bound. The instructions of how to make a lead tablet efficently for magickal uses could be found in ancient papyri and ancient tablets.
