A study by Denman Waldo Ross after the seventeenth-century portrait of Infante Don Carlos by Diego Velázquez, focusing on tonal composition and form.

This work is a study by the American painter and art theorist Denman Waldo Ross, based on the portrait of Infante Don Carlos by Diego Velázquez. Ross, a figure associated with the Museum of Fine Arts, Boston, produced this copy as part of his rigorous engagement with the techniques of the Old Masters. The original seventeenth-century portrait by Velázquez is noted for its sombre palette and the psychological depth of the sitter, qualities that Ross attempts to capture through his own painterly approach.

In this version, the figure of the Infante is rendered in a dark, monochromatic costume that blends into the murky background. The composition relies on the contrast between the pale, illuminated face and the deep shadows of the clothing. Ross employs a loose, gestural brushwork that differs from the precise finish of the Spanish master, reflecting his interest in the mechanics of colour theory and tonal balance. The subject holds a hat in one hand, a detail that maintains the formal posture of the original court portrait. The focus remains on the structural arrangement of light and dark, which was a primary concern for Ross throughout his career as an educator and collector. This print offers a view into the practice of copying as a pedagogical tool, allowing the viewer to observe how an artist of the late nineteenth century interpreted the methods of the Spanish Golden Age. The muted tones and the focus on form over fine detail make this a study in tonal composition, suitable for those interested in the history of art education and the reception of Velázquez in American collections.
