[Sidenote: p. 95.] And if one writes with copperas and fumigates it with a powdered gall-nut, the hidden letters will become clear. Also if one writes (with milk) and the paper is burned and the ash sprinkled on the letters written with the milk, they will be manifest.[113] And urine and garum[114] also and juice of the spurge and of the fig will have the same effect.
But when he has thus learned the enquiry, he thinks beforehand in what fashion he need reply. Then he bids the spectators come inside bearing laurel-branches and shaking them[115] and crying aloud invocations to the dæmon Phrēn. For truly it is fitting that he should be invoked by them and worthy that they should demand from dæmons what they do not wish to provide on their own account, seeing that they have lost their brains.[116] But the confusion of the noise and the riot prevents them following what the magician is thought to do in secret. What this is, it is time to say.
Now it is very dark at this point. For he says that it is impossible for mortal nature to behold the things of the gods, for it is enough to talk with them. But having made the boy lie down on his face, with two of those little writing tablets on which are written in Hebrew letters [Sidenote: p. 96.] forsooth[117] such things as names of dæmons, on each side of him, he says (the god) will convey the rest into the boy’s ears. But this is necessary to him, in order that he may apply to the boy’s ears a certain implement whereby he can signify to him all that he wishes. And first he rings[118] (a gong) so that the boy may be frightened, and secondly he makes a humming noise, and then thirdly he speaks through the implement what he wishes the boy to say, and watches carefully the effect of the act. Thereafter he makes the spectators keep silence, but bids the boy repeat what he has heard from the dæmons. But the implement which is applied to the ears is a natural one, to wit, the wind-pipe of the long-necked cranes or storks or swans. If none of these is at hand, the art has other means at its disposal. [Sidenote: p. 97.] For certain brass pipes, fitting one into the other and ending in a point are well suited to the purpose through which anything the magician wishes may be spoken into the ears. And these things the boy hearing utters when bidden in a fearful way, as if they were spoken by dæmons. And if one wraps a wet hide round a rod and having dried it and bringing the edges together fastens them closely, and then taking out the rod, makes the hide into the form of a pipe, it has the same effect. And if none of these things is at hand, he takes a book and, drawing out from the inside as much as he requires, pulls it out lengthways and acts in the same way.[119]
