The spell Marnie casts over Eric that causes his amnesia is Latin and comes from a conjuration from the Verus Jesuitarum Libellus (The True Petition of the Jesuits). The true Magical Work of the Jesuits;
containing most powerful charges and conjurations for all evil spirits of whatever state – condition or office they are.
Jam tibi impero et præcipio maligne spiritus! ut confestim hinc a me et summa illa pecuniarum allata et circulo discedas, absque omni strepito, terrore, clamore et foetore, asque sine omni damno mei tam animæ quam corporis, absque omni læsione cujuscunque creaturæ vel rei; et ad locum a justissimo Deo tibi deputatum in momento et ictu oculi abeas; et hinc proripias. Hoc tibi praecipio in nomine et virtute, potentia ac potestate sanctissimae Trinitatis, Patris +, et Filiis +, et Spiritus sancti +. Ecce crucem Domini! Fugite partes adversae!
Now I command and charge you, O evil spirit! that you immediately bring to me all that money, and then depart from the circle, abstaining from all noise, terror, tumult, and stench, and if you refuse I will damn you both in body and soul. And abstain from harming any creature or thing, and depart immediately to the place which God’s justice has appointed for you. Depart from my sight and flee from here. This I command in the name and virtue, potency and power, of the most Holy Trinity, the Father +, and the Son +, and the Holy Spirit +. Behold the cross of Lord! Fly away to other parts!
