An engraved portrait shows Johann Weyer at age 60. He is depicted with a balding head and a short beard. He wears a ruff collar and a buttoned doublet. His right hand rests upon a human skull, a traditional "memento mori" symbol used to reflect on mortality. His left hand holds a rolled document or baton, signifying his authority. In the upper left background, a framed plaque contains the motto "Conquer Thyself" original Latin: "VINCE TE IPSVM". The engraver Pieter Holsteyn signed the bottom left of the image frame.

JOHANN WEYER.

IN THE 60TH YEAR OF HIS AGE, IN THE YEAR OF SALVATION 1576.

Weyer was truly a great healer of life,
A physician who brings health to the sick and suffering.
He gives life-sustaining medicines for health to the ill,
And gentle remedies for all against soul-destroying anger.
The poet plays on the similarity between Weyer’s name in Greek, "Bieros," and the word for life, "Bios." The mention of "anger" refers to Weyer’s treatise "On the Disease of Anger" included in this volume.

You know the healing of the human body, not only as others do,
But you also know the cure for the soul.
Therefore, you are as much superior to others,
As the soul is superior to the body.
