The part in question 'I. Basilii Valentini, benedictini ordinis monachi, Germani, practica una cum 12. clavibus et appendice, ex germanico;' or 'Basil Valentine, a German monk of the Benedictine order, one study with the twelve keys and the appendix, [translated] from the German.'

In a walled enclosure, two seated men with crossbows aim at a square target with a circular bulls-eye, and a key atop it. Seven arrows have hit the target. Between these two men are four small roofed crosses and an open grave in which a man or resurrected corpse is standing with his hands uplifted. On the left of the grave, corn is sprouting. In the foreground a corpse lies in a ploughed field. On the left, a man is scattering grain. Behind the man four birds are eating the grain. Below the corpse is a cross. To the right stands a winged angel holding a scepter in its left hand, and blowing a trumpet held in its right hand.

In the eighth key, neither human nor animal bodies can be multiplied or propagated without decomposition; the grain and all vegetable seed, when cast into the ground, must decay before it can spring up again; moreover, putrefaction imparts life to many worms and other animalculae.
