Willem Jacobsz Baert (1636-84). Mayor of Alkmaar and Amsterdam

Van Everdingen renders the fabrics and accessories with meticulous brushwork, capturing the texture of the robe and the sheen of the gloves. Subtle chiaroscuro models the figure, creating a three‑dimensional presence against an unadorned backdrop, while the restrained palette emphasizes the sitter’s dignified bearing.

The portrait was produced during the later phase of van Everdingen’s career, when he was known for both portraiture and historical compositions. The painting entered the Rijksmuseum’s holdings as part of its Dutch Golden Age collection, where it remains on display as a representative example of 17th‑century civic portraiture.
