A detailed engraved portrait depicts Michael Maier, a German physician and alchemist, at age 49 in 1617. He is shown from the waist up, wearing a formal ruff and a patterned doublet with a chain and medallion, symbols of his status. He holds a small book in his hand. To his right is a heraldic coat of arms topped with a bird, and to his left is a vase containing flowers. The portrait is framed by a draped curtain. Below the image is a Latin inscription containing his motto and professional titles.
