Heart of Lead is an alchemical operation in which a heart of flesh passes through calcination, purification and fixation, the three conversions of metal, and re-emerges as the operator’s own cipher. Motto: “Plumbum in Argentum, Argentum in Aurum, Cor meum in Lumen.”

In the New World cycle, an operation in caves beneath Gary, Indiana, under Lake Michigan, was interrupted by three apprentices with a flashlight and a rifle, Ray among them. The lead stayed lead, and the operator’s heart was found turned to lead.
