A detailed ink study by Jac van Looij documenting the sixteenth-century keystone of Saint Ursula located in the Amsterdam Begijnhof.

This ink drawing by the Dutch artist and writer Jac van Looij depicts a specific architectural detail found within the Begijnhof in Amsterdam. The subject is a keystone, or sluitsteen, featuring a relief of Saint Ursula. The work captures the historical character of the site, focusing on the stone carving that dates back to 1574, as indicated by the inscription at the top of the composition.

Van Looij employs a precise, linear technique to document the texture of the masonry and the sculptural form of the saint. The drawing serves as a record of the urban heritage of Amsterdam, reflecting the artist's interest in the physical history of the city. The composition is structured around the vertical axis of the keystone, with the figure of Saint Ursula positioned centrally. Flanking her are smaller figures, while the surrounding archway provides context for the placement of the relief. The inclusion of a cherub motif at the base and the decorative cartouche above the date adds a sense of period-specific ornamentation to the sketch.

As a document of Dutch architectural history, the drawing provides a clear view of the craftsmanship present in the Begijnhof. The use of brown ink on paper gives the work a warm, archival quality, typical of late nineteenth-century topographical studies. Van Looij, who was also a significant literary figure in the Netherlands, brings a keen observational eye to this study, ensuring that the proportions and the relief work are rendered with clarity. This piece is suitable for those interested in the intersection of art, history, and the built environment of Amsterdam.
