C. J. S. Thompson,
The Mystery and Romance of Alchemy and Pharmacy
“ Moreover, I protest, be it man, woman, or servant who is my patient, to cure them of all things, that I may see or hear either in mind or manner, and I shall not betray that which should be concealed or hidden, but keep inviolable with silence; neither reveal any creature under pain of death. And therefore I beseech our gods that observing this protestation, promise, and vow entirely and inviolably, all things in my life, in my art, and science, may succeed securely, healthfully, and prosperously to me, and in the end eternal glory. ”
