Portrait of Augustijn van Teylingen

Jacob Cornelisz van Oostsanen painted this portrait of Augustijn van Teylingen in 1511, documenting a member of one of Amsterdam's prominent families. As the city's leading portraitist, Jacob Cornelisz captured Amsterdam's mercantile elite during a period of rapid commercial growth as the city rose to challenge Bruges and Antwerp. The oil medium allowed for rich tonal transitions and glazed layers of color that created luminous depth impossible with the older tempera technique. Portraiture in this period served multiple functions: documenting individual appearance, commemorating social status, and demonstrating the patron's wealth through the quality of the commissioned work.

The portrait displays Jacob Cornelisz's careful observation of physiognomy combined with decorative richness in costume details, set against a characteristic dark background.
