A portrait of the watercolourist Samuel Prout by the British painter John Jackson, executed in the early nineteenth century.

This portrait by John Jackson depicts the watercolourist Samuel Prout. Jackson, a contemporary of Prout, was a member of the Royal Academy and gained recognition for his ability to capture the likeness of his peers. The painting follows the conventions of early nineteenth-century British portraiture, focusing on the sitter against a dark, atmospheric background that directs attention to the facial features and expression.

Prout is shown in a three-quarter view, wearing a dark coat and a white cravat. The lighting is focused, creating a contrast between the illuminated face and the shadowed surroundings. Jackson employs a restrained palette, typical of his work, which allows for a focus on the texture of the clothing and the subtle modelling of the sitter's face. The brushwork is controlled, reflecting the academic training of the period.

Samuel Prout was a significant figure in the development of British watercolour painting, particularly known for his architectural studies of European cities. This portrait provides a record of the artist during his active years. Jackson's approach to portraiture often involved a directness that avoided excessive ornamentation, preferring to convey the character of the subject through careful observation. The work remains a representative example of the portraiture produced by the Royal Academy circle during the Regency era, documenting the professional connections between artists of the time.
