More years passed before Calid’s trusty slave, Galip, learned the identity and whereabouts of Morienus from another hermit of Jerusalem and was despatched with a large retinue to bring him back. The king and the hermit at first engaged in a moral and religious discussion, and many days passed before Calid ventured to broach the subject of alchemy. He then put to Morienus a succession of questions, such as whether there is one fundamental substance, and concerning the nature and color of the philosopher’s stone, also its natural composition, weight and taste, cheapness or expensiveness, rarity or abundance, and whether there is any other stone like unto it or which has its effect. This last query Morienus answered in the negative, since in the philosopher’s stone are contained the four elements and it is like unto the universe and the composition of the universe. In the process of obtaining it decay must come first, then purification. As in human generation, there must first be _coitus_, then conception, then pregnancy, then birth, then nutrition. To such general observations and analogies, which are commonplaces of alchemy, are finally added several pages of specific directions as to alchemistic operations. Such enigmatic nomenclature is employed as “white smoke,” and “green lion,” but Morienus later explains to Calid the significance of most of these phrases. “Green lion” is glass; “impure body” is lead; “pure body” is tin, and so on.
