IN the name of the blessed and Holy Trinity, I do desire thee, strong, and mighty angels (here name the spirits you would have appear) that if it be the divine will of him who is called Tetragrammaton, &c. the holy God, the Father, that thou take upon thee some shape as best becometh thy celestial nature, and appear to us visibly here in this place, and answer our demands, in as far as we shall not transgress the bounds of the divine mercy and goodness,
