Portret van Justus Lipsius, humanist en hoogleraar te Leiden en Leuven BN 861b

The scholar is depicted in a half-length view, wearing a formal pleated ruff and a heavy fur-trimmed coat. He holds a small book in his left hand while resting his right hand on the head of a small dog. The composition is framed by a Latin motto at the top and the artist's monogram on the right.

Justus Lipsius was the founder of Neo-Stoicism, a philosophical movement that sought to synthesize ancient Stoic ethics with Christian theology. His work was foundational to the intellectual landscape of the late Renaissance, influencing early modern natural philosophy and the development of political theory across Europe.
