A formal portrait of Thomas Hollis III by John Singleton Copley, depicting the benefactor in a scholarly setting with classical architectural elements.

John Singleton Copley painted this portrait of Thomas Hollis III in 1766. Hollis was a wealthy English merchant and a significant benefactor to Harvard College. The painting reflects the formal conventions of eighteenth-century portraiture, placing the subject in a setting that communicates his intellectual and philanthropic status. Hollis is depicted seated at a table, captured in the act of writing, which suggests his scholarly engagement and administrative duties.

The composition employs a balanced arrangement, with the subject positioned to the right of the centre. To his left, a large, ornate red vase stands against a classical architectural backdrop, providing a sense of scale and gravity. A heavy blue curtain drapes behind him, adding texture and depth to the interior space. Copley demonstrates his technical skill in the rendering of fabrics, from the sheen of the subject's coat to the delicate lace at his cuffs. The lighting is controlled, focusing attention on the face and the quill in his hand, while the surrounding environment remains somewhat subdued in tone.

Copley, who was born in Boston, became known for his ability to capture the likeness and social standing of his sitters with precision. This work is an example of his pre-London period, where he developed a style that combined colonial realism with the grand manner of British portraiture. The inclusion of the vase and the architectural elements serves to elevate the status of the sitter, aligning him with the traditions of European portraiture. The work remains a record of the transatlantic connections between colonial America and the intellectual circles of London during the mid-eighteenth century.
