But if he knows beforehand that any one present will ask a question, he is better prepared for everything. And if he has learned the question beforehand he writes it out with the drug (aforesaid) and as being prepared is thought more adept for having skilfully written what was about to be asked. But if he does not know, he guesses at it, and exhibits some roundabout phrase of double and various meaning, so that the answer of the oracle being meaningless will do for many things at the beginning, but at the end of the events will be thought a prediction of what has happened. [Sidenote: p. 98.] Then having filled a bowl with water, he puts at the bottom of it the paper with apparently nothing written on it, but at the same time putting in the copperas. For thus there floats to the surface the paper bearing the answer which he has written. To the boy also there often come fearful fancies; for truly the magician strikes blows in abundance to terrify him. For, again casting incense into the fire, he acts in this fashion. Having covered a lump of the so-called quarried salts[120] with Tyrrhenian wax and cutting in halves the lump of incense, he puts between them a lump of the salt and again sticking them together throws them on the burning coals and so leaves them. But when the incense is burnt, the salts leaping up produce an illusion as if some strange and wonderful thing were happening. But indigo black[121] put in the incense produces a blood-red flame as we have before said.[122] And he makes a liquid like blood by mixing wax with rouge and as I have said, putting the wax in the incense. And he makes the coals to move by putting under them stypteria[123] cut in pieces, and when it melts and swells up like bubbles, the coals are moved. [Sidenote: p. 99.] 2. And they exhibit eggs different (from natural ones) in this way. Having bored a hole in the apex at each end and having extracted the white, and again plunged the egg in boiling water, put in either red earth from Sinope[124] or writing ink. But stop up the holes with pounded eggshell made into a paste with the juice of a fig. 3. This is the way they make sheep cut off their own heads. Secretly anointing the sheep’s throat with a caustic drug, he fixes near the beast a sword and leaves it there. But the sheep, being anxious to scratch himself, leans (heavily) on the knife, rubs himself along it, kills himself and must needs almost cut off his head. And the drug is bryony and marsh salt and squills in equal parts mixed together. So that he may not be seen to have the drug with him, he carries a horn box made double, the visible part of which holds frankincense and the invisible the drug. And he also puts quicksilver into the ears of the animal that is to die. But this is a death-dealing drug.
