I have spoken with some, however, knights and men of this world, who deemed that he did but beguile our eyes by craft and sleight-of-hand.
This other hellish art he had, by direct inspiration, as I hold, of his master Behemoth, that he could throw his voice whither he would, so that, in all seeming, it came from above, or from below, or from a corner of a room, fashioning it to resemble the voice of whom he would, yet none might see his lips move.

With this craft he would affray the peasants about the fire in the little inns where we sometimes rested, when he would be telling tales of bogles and eldritch fantasies, and of fiends that rout and rap, and make the tables and firkins dance.

Such art of speech, I am advised, is spoken of by St.Jerome, in his comment on the holy prophet the saint Isaiah, and they that use it he calls "ventriloqui," in the Latin, or "belly-speakers," and he takes an unfavourable sense of them and their doings.

So much I have from the learned William de Boyis, Prior of Pluscarden, where now I write; with whom I have conversed of these matters privately, and he thinks this art a thing that men may learn by practice, without dealing in nigromancy and the black magic.

This question I am content to leave, as is fitting, to the judgment of my superiors.
