Portret van Johann Georg Mertz op 38-jarige leeftijd 1698

This engraving by Leonhard Heckenauer from 1698, titled "Portret van Johann Georg Mertz op 38-jarige leeftijd," portrays the subject in a three-quarter length pose, holding a book in his left hand. He is dressed in a black robe with a large, white ruff collar, a common fashion in 17th-century Europe. The work is a fine example of Baroque portraiture, with its emphasis on realism, detail, and the use of chiaroscuro (the contrast of light and dark). The setting is a simple interior with a shelf of books and a small crucifix visible in the background, hinting at the subject's religious vocation and intellectual pursuits. This work is currently on display at the Rijksmuseum.
