Conceived as a pair, these portraits of a Creole Woman from Guadalajara and a Creole Man from Mexico City are among the earliest known precursors to the Casta painting genre. By depicting his sitters in fictive oval frames, a format traditionally reserved for distinguished figures, de Arellano seeks to redefine and elevate the position of Creole families within Mexican society at a time of political upheaval. As the genera developed throughout the 18th century, Castas portraits became depictions not of actual individuals but of different racial types in the pluralistic colonial society. Their bold naturalism, sumptuous attire, and groundbreaking format tell a powerful story of social hierarchy, aspiration, and cultural hybridity in viceregal Mexico.
