This is a spell for a love potion preserved in the Greek ritual manual PGM VII, 969-972.
The title of the ritual and the initial instructions are encrypted and followed by a tachygraphic key.
A good potion: Take a piece of hieratic papyrus and write on it:
iaôô estabisa sêtour eô san athiach iô ouê nouaachêmachou: Let her, NN, whom NN bore, love me, NN, when she has drunk the drink!
