A formal portrait of Dutch historian Casparus Commelin, painted by David van der Plas in 1693, featuring the subject with his seminal work on Amsterdam.

This portrait by David van der Plas depicts Casparus Commelin, a notable Dutch bookseller, journalist, and city historian. Painted in 1693, the work captures the subject alongside his significant publication, 'Beschrijvinghe van Amsterdam'. The composition follows the conventions of late seventeenth-century Dutch portraiture, placing the sitter in a dignified, scholarly setting. Commelin is shown in a relaxed yet formal pose, wearing a loose-fitting banyan, a garment often associated with intellectuals and men of letters during this period. His long, dark periwig frames a face rendered with careful attention to naturalistic detail, reflecting the artist's skill in capturing individual character.

The inclusion of the book serves as a clear indicator of Commelin's professional identity and his contribution to the documentation of Amsterdam's history. The background features a subtle, somewhat allegorical element, with a small figure visible in the shadows, adding a layer of classical allusion common in the portraiture of the era. The lighting is focused on the sitter's face and the open pages of the book, creating a sense of depth and directing the viewer's attention to the primary subject matter. The palette is dominated by warm, earthy tones, typical of the period's preference for subdued colour schemes that convey a sense of gravity and tradition.

David van der Plas was active in Amsterdam and known for his portrait work. This piece provides a glimpse into the social and intellectual life of the city at the end of the seventeenth century. The texture of the fabric and the precision of the facial features demonstrate the technical proficiency expected of a painter in the Dutch tradition. This print offers a clear reproduction of the original oil painting, preserving the tonal balance and the atmospheric quality of the interior space.
