Athanor
This occult hill is surrounded by mist excepting the southern side, which is clear. It has a well, which is four paces in breadth, from which an azure vapour ascends, which is drawn up by the warm sun. The bottom of the well is covered with red arsenic. Near it is a basin filled with fire from which rises a livid flame odourless and smokeless, and never higher or lower than the edge of the basin. Also there are two black stone reservoirs, in one of which the wind is kept, and in the other the rain. In extreme drought the rain-cistern is opened and clouds escape, which water the whole country. The term is also employed to denote moral and philosophical alchemy.
