Between 1802 and 1808 De Wint was apprenticed to the portrait painter and mezzotint engraver John Raphael Smith. Smith would take him on fishing expeditions by the Thames, during which De Wint would sketch in oils. De Wint gained an early release from his apprenticeship on condition that he paint eighteen landscapes of various sizes for Smith over a two year period. The river depicted in this study has not been identified but could well be the Thames.
