Turba Philosophorum
The Thirtieth Dictum
Bacsen saith: Thou hast spoken well, O Diomedes, but I do not see that thou hast demonstrated the disposition of Corsufle* to posterity! Of this same Corsufle the envious have spoken in many ways, and have confused it with all manner of names. Then he:

Bacsen saith: I give notice, therefore, to future seekers after this Art, that Corsufle is a composite, and that it must be roasted seven times, because when it arrives at perfection it tinges the whole body.
The Turba answereth:—Thou hast spoken the truth, O Bacsen!
