Key passages

  • Borrhomeo! Beware of covetousness which is idolatry. On this sordid pursuit which you call a science, have you wasted your days on earth and your peace hereafter.

    The young man warns Borrhomeo that his greed for alchemical wealth is a form of idolatry that has ruined his life and soul.
