A detailed sixteenth-century engraving by Nicolaus Häublin depicting the Lutheran theologian Matthias Flacius with a book.

This engraving by Nicolaus Häublin depicts the Lutheran theologian Matthias Flacius, also known as Flacius Illyricus. The portrait captures the subject in a formal, bust-length pose, characteristic of sixteenth-century scholarly iconography. Flacius is shown wearing a traditional academic cap and a dark, heavy robe with a simple collar. His hand rests upon a closed book, a common attribute in portraits of theologians and intellectuals of the period, signifying his dedication to study and religious discourse.

Häublin employs a precise engraving technique to define the textures of the subject's clothing and the subtle contours of his face. The cross-hatching and parallel lines create a sense of volume and shadow, giving the figure a grounded presence within the frame. The composition is contained within a rectangular border, which mimics the appearance of a window or a niche. This framing device adds a sense of depth to the print, drawing the viewer's focus directly to the subject's intense gaze.

At the base of the print, a cartouche contains the Latin inscription identifying the sitter as 'Mathias Flaccius Illyricus', along with details regarding his birth in Albona and his death in Frankfurt in 1575. The lettering is executed with clarity, maintaining the formal aesthetic of the era's printed portraiture. This work serves as a record of the appearance of a significant figure in the history of the Reformation. The print reflects the technical standards of German printmaking during the late sixteenth century, where the focus remained on the accurate representation of the individual through controlled line work and balanced composition. It is a piece that offers insight into the visual culture surrounding the intellectual leaders of the Reformation.
