An example of an historical analogy:
"By the sixteenth century, the church had drawn up a document establishing correspondences between the various alchemical processes and church sacraments. Hence putrefaction was extreme unction; distillation, ordination; calcination, repentance; coagulation, marriage; solution, baptism; sublimation, confirmation; and of course, transmutation, the Mass."
Morris Berman (1981). The Reenchantment of the World. Cornell University Press.
