A 1767 portrait by John Singleton Copley depicting Boston merchant Nicholas Boylston in a silk banyan, reflecting the status and trade of the colonial era.

John Singleton Copley painted this portrait of the Boston merchant Nicholas Boylston in 1767. The work captures the subject in a moment of relaxed authority, seated in a study environment that reflects his status as a successful trader. Boylston wears a banyan, a loose-fitting dressing gown often associated with the Enlightenment era, which suggests a man of leisure and intellectual pursuit. The garment, rendered in a deep green with subtle damask patterns, contrasts with the crimson drapery behind him and the pink cap upon his head. Copley demonstrates his technical skill in the rendering of textures. The sheen of the silk banyan, the crisp white ruffles at the cuffs, and the heavy leather bindings of the books under Boylston's hand are depicted with precision. In the background, a small window reveals a maritime scene featuring a ship, a direct reference to the source of the sitter's wealth. The composition follows the conventions of eighteenth-century portraiture, placing the subject in a controlled, interior space that communicates his professional identity and social standing. This painting is part of a series of portraits Copley produced for the Boylston family. It remains a representative example of his pre-revolutionary American period, during which he became the most sought-after portraitist in the colonies. His ability to balance the material reality of his subjects with a sense of psychological presence defined his career before he moved to London in 1774. The work is currently held in the collection of the Harvard Art Museums, reflecting the historical connection between the Boylston family and the university.
