Hippolytus

“ Chalky earth is fashioned into the shape of a pyramid, but its colour is that of a milk-white stone, and it is prepared after this fashion. Having anointed the piece of clay with plenty of oil, and put it upon coals, and baked it, by smearing it afresh, and scorching it a second and third time, and frequently, (the sorcerer) contrives that it can be burned, even though he should plunge it in water; for it contains in itself abundance of oil. ”

“ The (sorcerer) , however, previously washes his hands frequently in brine; the consequence being, that the contents of the cauldron do not in any wise, though in reality boiling, burn him very much. But if, having smeared his hands with a tincture of myrtle [3] and nitre and myrrh, along with vinegar, he wash them in brine frequently, he is not scorched: and he does not burn his feet, provided he smear them with isinglass and a salamander. ”
